Choosing Your First Regulator

Posted by Featured Author on Tue, Aug 02, 2016 @ 02:08 PM

By Andy Phillips

Once you’ve decided to invest in your own regulator, the number of options out there can be intimidating. Here are a few helpful tips to help you choose your first one.

Choosing your first regulator is almost as much fun as choosing your first car (in our opinion). But with the plethora of options out there — DIN or yoke, balanced or unbalanced, black or color, your instructor’s recommendation, etc. — how do you know what’s right for you?

Your regulator is one of the most important investments you’ll make. You’ll rely on it for life support, and any problems/failures with your regulator are obviously more immediately concerning. Poorly maintained rental regulators tend to leak more, which depletes your air supply and can raise anxiety. They’re generally harder to breathe from as well, and may not be the most hygienic.

In short, if I could travel with only two pieces of dive equipment, I’d choose my regulator and dive computer. Drawing on my 20 years as a dive professional, as well as advice from two well-seasoned colleagues, we’ve put together a few tips for you to consider when it comes to choosing your first regulator.

DIN or yoke

Depending on where you’re purchasing and whether you ask, you may not have a choice. In North America, most retailers will offer yoke/A-clamp by default. In Europe or the U.K., you’ll most likely have the option to purchase a DIN. For more on the difference between a yoke and DIN configuration, check here. If you intend to do lots of deep or technical dives, or ones in overhead environments, we recommend DIN regulators. This connection tends to be stronger and is preferred for that type of diving. DIN regulators can easily be converted to yoke/A-clamp configurations with an adaptor (usually an additional purchase), or by removing a donut fitting from the valve face. That said, most first-time regulator purchases, at least in the U.S. and tropics, will be yoke-style, and these can be converted to DIN as well.

Budget or premium (often known as unbalanced or balanced)

While price shouldn’t be the only deciding factor on such a crucial piece of equipment, economics of course play a part in the decision-making process. Unbalanced regulators are at the lower end of the price spectrum. With both piston and diaphragm designs, these typically breathe a little harder as the tank pressure drops, when you’re breathing at deeper depths, or when two divers breathe at the same time. Balanced regulators tend to breathe evenly across the dive, both at depth and when your tank pressure drops. If money is no object, many are available in titanium or colored finishes. If you regularly dive at deeper depths, beyond 80 feet (24 m) or in challenging conditions, such as cold water or strong currents, then a balanced reg is the way to go.

Ease of service/parts

Frequent divers, especially those who travel a lot or aspire to a career as a dive professional, may want to choose a well-known brand such as Scubapro or Aqua Lung. These will be easier to find service or parts for those in remote locations. Your choice when it comes to unbalanced vs. balanced may also depend on how much you travel. On small islands and in remote locations you can usually get parts and service for an unbalanced regulator.

environmentally sealed regulator

Environmentally sealed

If you’ll be diving in cold water, an environmentally sealed regulator prevents potential freezing, which could result in a free-flow. In Europe, regulations require an environmentally sealed regulator for diving in waters as cold as 35 to 39 F (2 to 4 C). It’s also wise to purchase a sealed regulator to prevent debris build-up if you’re diving in waters that are high in silt, sand or other particulates. This type of regulator tends to be more expensive. If you cannot afford this feature when you buy it, you may be able to adapt or upgrade the regulator at a later date.

Additional features to consider

Venturi/inhalation assist: these valves make breathing from the second-stage diaphragm easier at depth and, when in the “off” setting, help avoid free-flows at the surface.

Miflex/length of hoses: While you can change hoses, they should configured in such a way that they’re comfortable for each diver to breathe from. If you’re using an alternate rather than an Air2 setup, it should be on a slightly longer hose (6 to 8 inches).Miflex hoses are popular with some divers due to their flexibility and versatility. If you pack your regulator in your carry-on luggage when flying, these hoses also make it easier to stow.

Number of ports: Ideally, you’ll have two high-pressure ports so that you’ve got the option to add an air-integrated transmitter as well as your submersible pressure gauge. The first stage should also have four low-pressure ports so that you can connect your primary air source, alternate air source, a low-pressure BCD inflator and a drysuit inflator hose.

Weight: As airlines get stricter and stricter on travel allowances, every bit of extra weight makes a difference. Many manufacturers have taken this into account and have made lighter or smaller first stages, but you should make sure this doesn’t affect performance or limit the features listed above. Many divers will travel with their regulator in their carry-on baggage to protect it, as well as reduce the weight of checked baggage.

The World’s Best Lake Dives

Posted by Featured Author on Tue, Aug 02, 2016 @ 02:00 PM

By Trevor Sanford

Although scuba diving is most frequently associated with the ocean, there are many amazing landlocked sites as well. Here are 10 of the world’s best lake dives.

Although people most often associate scuba diving and the ocean, there are plenty of amazing freshwater dives as well. There are roughly 42,320 square miles of lakes in the world — a tiny drop when compared to the ocean — but still a massive volume of water. Here are our picks for the world’s best lake dives, in no particular order, to get you started on your freshwater diving adventure.

best lakes for diving

Grüner See

Weissensee, Austria

Landlocked Austria features many lakes — you may be familiar with the crystal-clear water of the Grüner See (Green Lake, which unfortunately is no longer open to divers. Fear not, as the Weissensee (White Lake) also has amazing vis. The lake is around seven miles (11 km) long and 318 feet deep (97 m) at the deepest point. The water quality is purportedly nearly good enough to drink right out of the lake. During the summer, the surface temps can reach 75 F (24 C).  The lake is also famous for its ice diving, so it’s well worth a visit in the winter months.

Dolomitovy Pit, Russia

It may be off-the-beaten-scuba track, but Russia offers adventure aplenty. though the country’s vast size means travel planning is often quite complicated. We’ve chosen this former quarry lake, as it’s relatively easy to get to at only 14 miles (22 km) from Moscow. Created to mine dolomite, as well as minerals, the quarry is now home to trout, carp, pike and catfish that can reach up to eight feet (2.5 m) long. It’s no deeper than 46 feet (14 m), but the vis can be up to 66 feet (20 m) and in summer, water temps can reach nearly 79 F (26 C).

best lakes for diving

Yellowstone Lake

Yellowstone Lake, United States

Yellowstone Lake, the largest single body of water in the famous Yellowstone National Park, is located 7,733 feet (2,316 m) above sea level and covers 125 square miles (324 square kilometers). The lake spends much of the winter under ice, but even during the summer the water is cold, between 40 and 60 F (4.4 to 16 C). There are five sites in the lake, and one in the Firehole River. The main draw here are the same thermal features that are so famous on land, creating steady streams of bubbles venting all around you. You can get near the vents in some cases; in some you should maintain your distance.

Lake Huron, Canada

The Great Lakes offer some stellar wreck diving. One of the best spots is Tobermory, on Lake Huron. The self-proclaimed “freshwater scuba capital of the world” is situated on a peninsula and, in the 1800s and early 1900s, was a busy port surrounded by treacherous waters, which means today’s scuba divers are spoiled with over 20 wrecks. Many of the ships are still well preserved due to the cold water, the most famous perhaps being the Caroline Rose schooner, seen in many photos lying in crystal-clear water just offshore.

 

best lakes for diving

Þingvallavatn Lake

Þingvallavatn Lake, Iceland

Bucket-list alert! You’ve probably heard of this spot because of the stunning dive site that is the Silfra Fissure. Silfra is probably on every cold-water diver’s list — and should be on everyone’s list — with good reason. The fissure’s location means you can dive between the North American and European tectonic plates on the same dive — two continents literally a fin-kick away. There are three main dive sites, know as Silfra Hall, Silfra Cathedral and Silfra Lagoon. The deepest point is 206 feet (63 m) and water temperatures rarely go above 39 F (4 C). The most spectacular of the dives is at the Silfra Cathedral, a 328-foot-long (100 m) fissure, with sparkling visibility from end-to-end in the glass-clear water. You will need a permit.

Pet Cemetery Cenote, Mexico

This is definitely not your normal lake dive. When limestone bedrock collapses, it can form cenotes, or underground lakes, which draw from divers around the world. There are many intriguing cenotes out there, but for this list we’ve chosen Pet Cemetery south of Playa Del Carmen, on Mexico’s Riviera Maya. Part of the world’s second-largest underwater cave system, you can dive this cenote without full cave training. This makes it accessible to many more divers. It’s not very deep, only 10 feet (3 m) on average, but it’s stunning, featuring stalactites, stalagmites and the bones of long-gone animals (from whence it got its name). Buoyancy is key here, as the formations are delicate and you will ruin the vis by kicking up the sediment. So best practice your trim before you go.

best lakes for diving

Piccaninnie Ponds

Piccaninnie Ponds, Australia

Located near Mt. Gambier, South Australia, this site is a coastal spring that filters through limestone, making for crystal-clear waters. It’s said to be one of the most beautiful freshwater locations in Australia. There are two main features to draw divers — the Chasm, which has a depth of 328 feet (100 m), and a chamber know as the Cathedral. Properly qualified cave divers can check out the caves, though you can also snorkel here.  Both divers and snorkelers need a permit and a time-slot allocation; check here for more information.

Capo D’Acqua, Italy

To the east of Rome, in Central Italy, lies a manmade lake. Created in the 1950s to act as irrigation reservoir for the surrounding land, Capo D’Acqua contains the ruins of two old mills and a partially submerged factory that date back to the Middle Ages. The waters are very clear and temps vary between 59 F and 79 F (15 to 26 C) over the year. Note that before you head to this site you’ll need a permit, which you can get from the local dive center, as the lake is on private land.

best lakes for diving

Lake Baikal

Lake Baikal, Russia

Earlier we highlighted an “easy” entry into Russian dive sites — now we’ll get a bit more adventurous and head to Lake Baikal in southeastern Siberia. The massive lake, about the size of Belgium, is the oldest, deepest and largest lake in the world by volume, containing around 20 percent of all the fresh water on the planet. At its deepest, the lake is 5,387 feet (1,642 m), and is home to more than 2,000 species of plants and animals, many of them endemic, including the nerpa, one of the world’s only freshwater seals.

There are diving possibilities year-round, but Baikal is perhaps most spectacular in the winter, when the lake freezes over and creates amazing vis on ice dives due to the purity of the water. Note that topside temps in winter are between -13 and 41 F (-25 to 5 C) and under the ice, the water is just above the freezing point. Summer water temps vary from 39 to 64 F (4 to 18 C).

Vättern, Sweden

Vättern is one of the deepest and largest lakes in Europe, with a maximum depth of 420 feet (128 m), but with an average depth of 135 feet (41 m). South of Stockholm roughly three hours by car, Vättern is famous for the excellent quality of its water, with many local communities using it for drinking water. The lake holds plenty of life, with over 30 species of fish, including a supposed “lake monster.” There are also a number of wrecks in the lake, at varying depths from recreational to tec-diving only.

Making a Proper Scuba Descent

Posted by Featured Author on Tue, Aug 02, 2016 @ 01:55 PM

By Thomas Gronfeldt

When it comes to safety, starting your dive properly sets the tone for the entire experience.

Making a proper ascent gets much of the attention when it comes to safety and scuba diving. From safety stops, to ascent rate, to avoiding traffic on the surface, a lot of training involves rising from the bottom. But descending for your dive is equally important, although course work does not emphasize it as much. Read on for tips on the best procedure for making a proper scuba descent.

Preparation for a proper scuba descent

Before you even start your descent, complete a few steps to ensure that you’re ready to descend at all. Preparing at the outset of a dive means that you won’t waste time remedying a situation once you’ve already begun.

1.     Check your gear.

Before getting in the water, make sure you have everything you need for the dive. Make sure that everything is in its place and secured. There’s nothing worse than trying to descend, only to find that you’ve forgotten your weights.

2.     Check the current.

Again before jumping into the water, check the current, both direction and strength. Knowing which way the water is moving will help you decide where to descend, or even if you should consider pushing the dive to a later time or date.

3.     Check that you’re at the right location.

Once you’re in the water and just before you’re ready to descend, look down to make sure you’re above your intended start point. Confirm the direction you’ll be heading in once you’re at depth.

4.     Check your brain.

You should already have checked in with yourself to make sure that you’re physically and mentally ready to dive, and that you simply feel good about the dive. But just as you’re about to descend, take a few seconds and a few deep, calm breaths to center yourself. Become present for the dive. Focus your mind on the activity at hand.

5.     Make eye contact.

Finally, find your buddy and make sure you’re both ready to dive, and are within a reasonable distance of each other before you begin your descent.

The descent

Now that you’re prepared, you can begin your actual descent.

1.     Let air out of your BCD and start the descent.

Start by letting all the air out of your BCD. You’ll float at about eye level in the water if you’re properly weighted. Exhale, pushing a bit more air out than you would during a normal exhalation, and feel yourself starting to sink. Once you’re a few feet below the surface, begin breathing normally again, but don’t take overly deep breaths, as these will make you buoyant enough to bring you back to the surface. This is probably the most common reason that new divers struggle to descend, a problem they often address with additional, and unnecessary, weight.

2.     Equalize your ears.

As the saying goes, equalize your ears “early and often.” Start your equalization as soon as your head goes below the surface, and continue to do so in frequent intervals as you descend. The more often you equalize, the less force you need to apply, and you may find you need only to wiggle your jaw a bit if you get it right.

3.     Keep an eye on the dive site and your buddy.

As you start to sink, keep an eye on your dive site, make adjustments for any current, and stay in touch with your buddy. Depending on the current or how far you are from your dive location, you can start slowly finning in the appropriate direction once you’re about 10 feet below the surface. Until then, you should be vertical in the water. This will not only help with your descent, but will also keep your sinuses above your lungs, which helps with equalization.

4.     Add air to your BCD.

As you descend, the inherent buoyancy from your exposure suit, the air in your tank, and whatever else is giving you buoyancy decreases, so you’ll start sinking faster and faster. To avoid descending too fast, add small amounts of air to your BCD to slow your descent. While we always talk about safe ascension rates, we should also make sure we don’t descend too fast. The deeper you go; the more air you’ll need to add.

5.     Come to a hover.

As you reach the bottom or your intended depth, add a bit more air to your BCD to achieve a complete hover. Stop here for a breath or two to ensure that you’re actually correctly buoyant. You should neither sink nor float up, and only change depth minimally when you inhale or exhale. Movement, such as finning, creates buoyancy, so taking a moment to hover without movement helps ensure that you are neutrally buoyant before venturing off.

6.     Make like Tom Cruise.

Whenever I have new divers on a course, I challenge them to do a Mission Impossible dive. I ask them to descend vertically until they’re almost at the bottom, and then assume a horizontal position. Whoever can come closest to the bottom without touching it wins. My students practice this challenge on every descent as long as the bottom surface is suitable, i.e., a sandy bottom without any coral or anything else that can be damaged.

With just a bit of forethought, training, and a few good procedures, a proper descent can help kick your dive off right.

Court Rules in Favor of Marine Mammals in U.S. Navy Sonar Debate

Posted by Featured Author on Tue, Aug 02, 2016 @ 01:50 PM

By Jessica Macdonald

After a protracted legal battle, a federal appeals court in San Francisco has ruled that the low-frequency active sonar used by the U.S. Navy constitutes a violation of the Marine Mammal Protection Act.

In 2012, the National Marine Fisheries Service (NMFS) granted permission for the Navy to use low-frequency active sonar as part of its peacetime training and testing activities. The approval was valid for a period of five years, and applied to exercises in the Indian, Pacific and Atlantic Oceans as well as the Mediterranean Sea. In the same year, environmental groups led by the Natural Resources Defense Council (NRDC) filed a counter-suit, claiming that the approval put vulnerable cetacean and pinniped species at risk and did not fulfil the terms of the Marine Mammal Protection Act.

Whales_on_beach,_Farewell_Split,_South_Island,_New_Zealand

On July 15th, California’s Ninth U.S. Circuit Court of Appeals ruled in favor of the environmentalists. The Marine Mammal Protection Act states that peacetime oceanic programs must have “the least practicable adverse impact on marine mammals,” a stipulation that the court unanimously agreed the approval had failed to uphold. The court did not place the blame on the U.S. Navy, however, which it stated “has been deliberate and thoughtful in its plans to follow NMFS guidelines and limit unnecessary harassment and harm to marine mammals.” Instead, the court pointed the finger at NMFS.

The terms of the original approval required the Navy to shut down or delay sonar use when a marine mammal was detected near the ships, and also banned sonar pulses near coastlines and in protected waters. However, the court ruled that the areas classified as “protected” by the NMFS were inadequate, in reality doing very little to shield vulnerable marine mammals from sonar-generated sound waves capable of reaching 235 decibels. To put that into perspective, the sound of a 12-gauge shotgun being fired is 165 decibels, while the average rock concert reaches just 115 decibels.

Underwater, sonar sound waves can travel for hundreds of miles. They are found in approximately 70 percent of the world’s oceans, and can measure up to 140 decibels at a distance of 300 miles from their original source. Scientists believe that this noise pollution causes severe stress for marine mammals by interfering with their echolocation and communication systems, and forcing them to alter their feeding and mating behavior. According to NRDC’s Marine Mammal Protection Project Director Michael Jasny, “marine mammal species perceive these [sonar] sounds as a threat and react accordingly.”

Navy sonar exercises have been linked to several mass strandings, including the 2002 stranding of 14 whales in the Canary Islands. Autopsies showed that the whales had gas bubbles in their tissues, leading some to hypothesize that sonar may cause decompression sickness in cetaceans. At this point, it is not clear what the court’s ruling means for the future of U.S. Navy low-frequency active sonar. The case has been returned to the district court for further consideration, but it is hoped that scientists will eventually find a way for marine-mammal conservation and national defense to co-exist.

Becoming a Drysuit Diver

Posted by Featured Author on Tue, Aug 02, 2016 @ 01:42 PM

Open up your underwater world by becoming a drysuit diver.


Although so much of the ocean qualifies as cold water, the majority of divers learn the basics of scuba diving in tropical waters, and remain there for their entire dive careers. But there’s no need to restrict your diving horizons: it’s time to try a drysuit.

If someone asked me if I’d like to visit the Alps in winter to ski I wouldn’t say no because “the snow looks a bit cold.” I’ve always held the same philosophy when it comes to diving: You just need the correct clothing and equipment. A drysuit opens doors to explore everything from winter diving in the Mediterranean, to Scotland’s Scapa Flow wrecks, to ice diving.

A drysuit can be worn anywhere but is typically used in water that’s colder than 59 to 68 F (15 to 20 C). According to several diving historians, the first drysuit was introduced by George Edwards in 1838. It’s evolved over the decades but does essentially the same job. Where a wetsuit lets in a small amount of water that is subsequently warmed against the body, the drysuit is water and air-tight. Zipped into your trusty drysuit, you’re sealed at the neck and wrists to keep the water out and a layer of air inside, which is used to maintain body temperature and help control your buoyancy and positioning while in the water.

What’s the first step?

If you’re ready to take the plunge into drysuit diving, there are a few considerations and a slightly amended diving style you’ll need to become familiar with. Although there’s nothing preventing you from simply buying a drysuit and jumping in, you’ll do well to first contact your local dive center and enroll in a drysuit specialty training course. Most major training agencies such as PADI offer such courses. The training allows you to become accustomed to drysuit diving under the guidance of a diving professional, as well as to learn about the suits themselves, their valves, undergarments and accessories. You’ll also learn basic repair and maintenance of drysuits. In addition to the classroom sessions, there’s also some practical assessment. PADI and SSI, for example, include two open-water dives in their training program, during which you’ll practice new techniques. For example, a large part of your buoyancy control comes via air you’ll add to the suit, usually through an “Iron Man”-style inflator button on your chest. Gas is then vented via dump valves, usually located on your left shoulder or wrist.  This new skill takes a little practice and is best done with the advice and supervision of an instructor.

What type of drysuit should I get? 

Once you’ve taken the class and decided you like drysuit diving, you’ll most likely want to invest in one of your own, if you’ve got the financial means. First, make sure you purchase the correct type of drysuit for your environment and undergarments. Most major manufacturers sell off-the-shelf suits in standard sizes, but a made-to-measure suit is the way to go for the best fit and comfort.

Drysuits come in a range of materials, but most divers opt for neoprene or trilaminate. The foam neoprene or crushed-neoprene suits tend to be slightly thicker; on first wearing one, people often report that they feel bulky. However, the additional thickness makes the suits tougher and slightly hardier than their trilaminate cousins, which can be important if you’re wreck diving or working in a tougher environment. In addition, in the unlikely event that a neoprene suit floods, it will retain some basic thermal protection — not much, but some.

Under a neoprene drysuit you’ll typically wear thermal base-layers; many manufacturers offer their own bespoke base-layers. The number of layers you wear will depend on your own thermal characteristics, the length of your dive and, of course, the water temperature. Be aware that the more layers you wear, the more weight you’ll need to carry.

Trilaminate or ‘shell’ suits are thinner and more flexible than neoprene, which makes them easier to transport and, usually, to get on and off. They’re not quite as hard-wearing as neoprene suits, however, and being thinner means they’re slightly more prone to puncture either in transport, storage or if you’re a little careless on a wreck. Typically, these are worn worn with a thick under-suit that resembles a sleeping bag.

Whichever construction you choose, fit is most important. Consider the following:

  • Is the construction right for the environment, both in terms of temperature and activity?
  • What undergarments do I need to wear underneath to stay warm? Will they fit comfortably and still allow the suit to vent air safely?
  • Do the neck and wrist seal fit snugly, but not so snugly that restrict blood flow?
  • Are the boots sufficiently large enough to wear the booties or thick socks I’ll be wearing underneath?
  • Are the arms long enough to allow me to make adjustments to my mask, BCD and hoses?
  • Will my computer fit comfortably over my wrist?
  • Will my fins fit?

Once you’ve decided on the suit’s construction, you’ve got a few other decisions to make — Front entry or rear entry? Shoulder or cuff dump valve? Neoprene or latex wrist and neck seals? Dry or wet gloves? Pee valve or no pee valve? Boots included or rock boots?

The drysuit is an amazing invention, and when you master its use, you’ll realize you no longer need to feel intimidated by either its operation or cold-water diving. With the correct training and experience, drysuit diving opens up a brand new world of water.

Cebu is World's Best Island

Posted by Ericka Villa on Mon, Aug 01, 2016 @ 12:48 PM

Three Philippine islands made it to the rundown this year in New York-based magazine Travel + Leisure's World's Best Islands list. 

Cebu is World's 6th Best Island.


Palawan, Boracay and Cebu arrived in the worldwide travel magazine's rundown, with Palawan securing the top rank in the wake of getting the most astounding score among readers at 93.71. This is the second time that Palawan was named the "world's ideal" in the rundown. It initially achieved the top spot in 2013.

T+L writer Melani Lieberman was astonished by Palawan's rebound as she depicted the spot where “visitors are greeted with mountains rising out of impossibly turquoise waters, where shipwrecks and reefs make for prime scuba diving and snorkeling. Palawan is known for its five-mile-long underground river regarded as one of the world’s wonders of nature.

“Palawan is every beach lover’s dream destination,” said one voter, who regarded it as a “wonderful and magical place.”

As Palawan ruled the worldwide travel magazine's rundown, Boracay caught the second spot and Cebu made it to the main 6 with 90.47 and 88.65 scores among readers, separately. Boracay additionally used to beat the "World's best Islands" list.

A reader said Cebu is the island “perfect for travelers who don't want to spend a lot of money on recreational activities.” The reader added that “there is never a dull moment in Cebu” as Lieberman cited that among the activities to be tries are hiking through canyons, swimming with whale sharks, and diving from the top of a waterfall.

“The Philippines’ predominance shows that discerning travelers are willing to travel great distances for the rewards of clear waters and sugary white beaches,” Lieberman said.

This is such great news for locals like me.  What a great delight it is to be in the same island where hiking through the canyons, swimming with whale sharks, and diving from the top of a waterfall is made possible by traveling only for a few hours. 

But of course, foreigners and tourists are more than welcome to visit our beloved island to enjoy, relax and witness how beautiful the Philippines is. Turtle Bay Dive Resort can assist and offer you a quality accomodation and the best deals that will take you to these places. 

Now, I'd like to share a glimpse of what T+L writer have mentioned. Enjoy these breathtaking photos! :)

DIN Versus Yoke Valves

Posted by Featured Author on Wed, Jul 27, 2016 @ 11:58 AM

By Thomas Gronfeldt 

Increasingly, manufacturers are producing tank valves with the newer DIN valve, and debates on scuba diving forums around the web are brimming with discussions as to which one you should use. Let’s try to clear that up.

As a scuba diver, you’re probably quite comfortable with the yoke valve. It’s been standard almost since scuba was invented. Increasingly, however, manufacturers are producing tank valves and regulators with the newer DIN valve. Scuba-diving forum debates brim on the web with discussions as to which one you should use. Let’s try to clear up the pros and cons when it comes to DIN versus yoke valves.

Yoke

Yoke

First, what is the difference between them? The yoke is a clamp-type mounting, which is placed over the tank valve and then tightened into place. The DIN is a threaded valve, wherein you screw the regulator into the tank valve. On the yoke valve, the main O-ring that seals the tank valve to the regulator first stage is placed on the tank valve. On the DIN, it is placed on the regulator first stage.

The name “DIN” is an acronym for Deutsche Industrie Norm, an industrial testing and approval agency based in Berlin, Germany. The agency standardizes a range of products, about 30,000 at present, within the fields of mechanics, engineering and technology. However, the DIN valve was actually invented in the U.S. In the late 1950s, American diving manufacturer Poseidon launched what they named their “⅝-inch Threaded Connection.” But it didn’t enjoy much public support and the yoke valve became the standard for scuba diving. When DIN tested valves on pressure tanks for industry use, including commercial diving, they made the ⅝-threaded their standard, and it thus inherited the name of the organization.

DIN Valve

DIN

Why DIN?

The German agency chose DIN for its higher pressure capacity, which comes in handy for industrial use and commercial diving. Whereas a yoke valve is generally only approved to a maximum working capacity of 200 bars, a DIN valve can be set up to handle up to 300 bars.

The first recreational divers to use the DIN were technical divers, not only because the extra capacity of 300 bars may come in handy, but also because of the increased safety that the DIN claims. The safety issue has long been a point of discussion among divers; some claim that anything but DIN is downright lethal, while others claim that the DIN isn’t really safer than a yoke at all.

Theoretically, the DIN does have safety advantages. The greater pressure capacity can reduce the risk of a rupture in case of overfilling when the tanks are attached to a compressor. Sine the O-ring in a DIN is in the regulator, rather than on the exterior of the valve as in the yoke, it’s less likely to be lost or damaged during transport. Tests have also shown the DIN to be more resilient to impact compared to a yoke, which can be knocked off — an unlikely, but not impossible, scenario.

Why yoke?

However, don’t jump to any conclusions about the yoke valve. Millions of dives have been conducted with yoke valves since scuba diving became popular, and it’s been proven to be plenty safe. It’s similar to debating whether the new Airbus 380 is safer than the old Boeing 737. On paper, the 380 has more safety features, but the 737 has millions of air miles to its name, with minimal accidents. It is also worth noting that DAN and other dive-safety organizations do not have policies against yoke valves. Technical diving, as a different discipline, may call for different tools. Tec divers do sometimes use higher working pressures in their tanks, up to 300 bars. When diving inside wrecks and caves, the increased protection against catastrophic impact damage, however marginal that risk, is worthwhile.

The tanks you rent on vacation typically feature yoke valves, so most traveling divers choose a yoke to ensure compatibility. If you prefer DIN, but still want to rent tanks, it’s usually a matter of removing a small insert from the yoke valve so that it will accept the DIN reg. If this doesn’t work, there are also DIN/yoke converters that will fix the problem.

A personal choice

Price-wise, the playing field has leveled in recent years, too. In the past, DIN was only available for high-end or tech-specific dive gear. Today, many entry-level regulators offer either a yoke or DIN, depending on the customer’s preference.

So, if you’re primarily a tec diver, you’ll probably want to go with DIN. If you’re not a tech diver, it’s a personal choice. The cost is about the same, and you can easily remedy the problems of traveling and renting gear. Considering the DIN’s advantages, however small, even for recreational divers, I dive with a DIN. But again, it’s a purely personal dive choice.

Improve Strength and Breathing for Diving

Posted by Featured Author on Wed, Jul 27, 2016 @ 11:54 AM

By Gretchen M. Ashton

Performed on an exercise ball, the pike abdominal and push up target the chest and abdominals, and have many benefits for divers.

To improve your strength and breathing for diving, it’s best to target a group of muscles. The pike abdominal and push up is a complex exercise set that targets the chest and abdominals, but has many additional benefits for both the assisting muscles, such as the shoulders, and antagonist muscles such as the triceps, involved in the movements. Performed on an exercise ball, the sequence is broken down into several separate moves to allow easy transitions in strength and confidence.

Some positions help strengthen the shoulders and back while also acting as safe alternatives for divers with shoulder or back injuries, so find the combination that works best for you. One of the biggest advantages of this exercise, when it comes to diving, is that while you’re strengthening your upper body and torso, you’re simultaneously training your body to support deep, relaxed, and controlled breathing for diving. Believe it or not, better breathing when it comes to diving is attainable by strengthening the muscles of the chest and torso.

Better Breathing, Better Diving

It’s important to integrate deep breathing into all exercise programs. Especially for divers, practicing deep breathing during abdominal exercises is an excellent opportunity to focus on recruiting the diaphragm muscle, which is responsible for 75 percent of respiratory air flow, and the intercostal muscles, which move the ribs, resulting in 25 percent of respiratory effort. The most recognized chest muscles, pectoralis major and pectoralis minor, often called simply the “pecs” are located in front of the ribcage. They add another layer of protection to the chest when it comes to diving. Studies indicate that the pectoralis major is active during both inhalation and exhalation. The more stable the chest, acting along with the diaphragm, the greater potential for increased lung capacity and oxygenation of the tissue, making the difference between fatigue and endurance. Conversely, tight chest muscles may inhibit breathing capacity and can limit range of motion in the shoulders. When performed properly, strength exercises actually help to actively stretch and expand the chest.

Walk Out on Exercise Ball

Ball Walk Outs: A great way to develop upper body and torso (abs and low back) strength is to support the body on an exercise ball while walking out with the hands. Set up as shown above with the ball under the hips or thighs. With arms extended under the shoulders, walk forward with the hands, rolling the ball along the body until it reaches your shins. Reverse direction and repeat while maintaining balance and keeping the ball moving along the center line of the body. Focus on balance and breathe rhythmically throughout the exercise. This exercise is an excellent alternative to push-ups for divers with shoulder injuries.

Remember to warm up with 10 minutes of aerobic exercise. Begin with an abdominal contraction when walking out on the ball, and let strength and proper form dictate range of motion.

Push Ups with Feet on Exercise Ball

 

Push-ups on the exercise ball: Push-ups are one of many ways to develop upper-body strength for scuba diving. Divers working to master push-ups may find the exercise ball makes the movement easier. Ideal range of motion at the bottom is when the elbows are at just less than a right angle. Remember to fully extend the arms at the top, but do not lock out the elbows. A good beginning goal is to complete five to 15 push-ups. With practice, sets of 25 to 100 are possible. If divers feel pain or strain in the shoulders they should stop until shoulders are confirmed as healthy enough to perform push-ups.

Pike Abdominal

Pike crunch on ball: Divers may take the exercise up a notch by flexing the hips while rolling the ball toward the chest with the feet. This pike position requires a good foundation of overall body strength to perform. It’s a great way to increase strength in the upper body, abdominals and low back, and improves balance and coordination. Repeat the pike about 10 times or alternate with a push-up. When combining the pike with the push-up, make sure to return to a straight body position before performing the push-up.

We’ve managed, in this modern era, to explore much of the ocean’s surface and its shallower realms, but the deepest portions of the ocean remain nearly as mysterious as they were eons ago.

As most of us know, our planet is more than 70 percent water, the vast majority of it in the oceans. Human beings have always looked to the ocean’s horizon, wondering what lies beyond. We’ve managed, in this modern era, to explore much of the ocean’s surface and its shallower realms, but the deepest portions of the ocean remain nearly as mysterious as they were eons ago. Although we do have a map of the ocean floor to a resolution of around 3 miles (5 km), it’s less detailed than ones we have of the surface of the Moon and Mars.

How deep can we dive?

Exploring the ocean’s depths poses numerous obstacles, including the crushing pressure that increases rapidly the deeper you go. Nevertheless, we’ve pushed on, trying to break records by diving deeper and longer with each passing year. Current records for most of the diving categories are awe-inspiring and leave us wondering how in the world these freedivers manage to pull feats such as these.

In this spirit of discovery and always pushing the limits, check out this cool infographic about just how far we’ve explored — and how much more we’ve yet to explore.

5 Ways You Can Be A Better Dive Buddy

Posted by Ericka Villa on Tue, Jun 28, 2016 @ 11:51 AM

Better Dive Buddy

We all learn about the buddy system when we start diving but with increased experience and confidence it is easy to forget the essential basics. The buddy system is not just for beginners, it is important for the safety of all divers in a group.

Want to be a better dive buddy? Here are 5 essential tips you should never forget.

Always remember your buddy check

Just because your equipment worked fine yesterday doesn’t mean that you haven’t missed something today. If your Divemaster sees you running through the buddy check he will recognise that you are responsible divers before you even enter the water.

Use the BWRAF acronym to help remember the buddy check steps. Begin With Reviewing A Friend

Always maintain buddy contact and communicate often

This doesn’t mean that you need to swim on top of each other. As a general rule, try to be no more than 2 seconds apart. In an emergency you may need each other and it helps the Divemaster control the group if you are together. Don’t forget to ask your buddy if they are “okay” regularly. Diving really is more fun with a buddy and you’ll get to share some incredible moments together. If your Divemaster sees you communicating he’ll recognise your dedication to each other and to safety.

Remember that you are a buddy “team” and diving is not a competition

Be encouraging towards your buddy but never force them into a dive they don’t want to make. If you or your buddy are unsure about anything, ask your Divemaster together for advice and guidance.

Dive, dive, dive

The more you dive the better you get. By diving in a range of conditions and environments you’ll broaden your skill base and diving knowledge, increasing yours and your buddy’s dive safety.

Continue learning

If you have just passed your PADI Open Water Diver Course consider moving on to Advanced Open Water. You’ll learn new skills and try different types of diving. When you have completed your Advanced certification, you’ll be ready for the Rescue Diver Course which equips you with the skills and knowledge needed to be able to perform self-rescues, rescue other divers and recognise potential problems before they develop.

Following these 5 steps will help you become a better dive buddy.  Contact your local PADI Dive Center or Resort to find out course information or to find some more dive buddies of your own!
