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.

Why Touching Is Never Okay

Why Touching Is Never Okay

By Jessica Vyvyan-Robinson


Respecting the ocean is a huge part of being a responsible diver, as is the understanding that we are privileged visitors to the underwater world and should conduct ourselves accordingly.

Any good Divemaster’s briefing always includes a reminder not to touch, tease or take anything from the marine environment, and the mantra “take nothing but photos, leave nothing but bubbles” is one that every diver will have heard at some point. Respecting the ocean is a huge part of being a responsible diver, as is the understanding that we are privileged visitors to the underwater world and should conduct ourselves accordingly.

Touching underwater creatures and corals can not only harm them; doing so can harm us too. There are many animals in the ocean that can cause injury if alarmed, disturbed or aggravated, some of which we know about, and many more that we do not. From innocuous looking stinging hydroids to the beautiful but venomous lionfish, from shells equipped with deadly poison to all manner of stonefish, scorpionfish, sea snakes, urchins and jellyfish, marine inhabitants are better admired from a distance suitable for your health as well as theirs.
Contact with the reef itself can cause nasty wounds; many of us know from firsthand experience how long coral cuts take to heal, and how disproportionately painful even the slightest graze can be. The majority of shark bites among divers occur as a result of inappropriate behavior or reckless contact on the part of the diver. As divers, we are ambassadors for the ocean and all the creatures that live there. Particularly where threatened species like sharks are concerned, our ability to interact with them without incident is key in changing public perception of them and consequently promoting their conservation. If we follow the no-touching, -teasing or -taking rule, we can easily avoid most injuries caused by marine life.
As divers, we have the potential to do great good in the underwater world. Through our explorations, we raise awareness about the marine environment and the necessity to conserve it for future generations. Divers tend to be among the most committed and conscientious promoters for ocean preservation — it’s our dive sites that we’re fighting to protect. By refraining from touching the creatures and plants that make up that world, we ensure that our impact continues to be a positive one.

How To Make A Successful Shore Entry

How To Make A Successful Shore Entry

By Jessica Vyvyan-Robinson


Depending on where you live, or where you travel, you may find that the simplest way to dive is from the shore. There are excellent shore diving sites all over the world, and as well as saving you the cost and travel time of boat diving, shore diving offers the freedom to choose where and when you want to dive, how often and for how long. 

Pre-dive planning

The “plan your dive, dive your plan” mantra is one emphasized over and over again to all divers during entry-level training, and it’s particularly applicable to shore diving. Attempting a shore entry in a place that you’ve already dived a hundred times is one thing, but when visiting a site for the first time it’s imperative that you know what to expect. Researching a shore diving site means finding answers to a long list of questions, from dive conditions to the rules surrounding scuba diving in a particular area. You will need to know what to expect underfoot, as there is often very little visibility in the surf zone and your head will be above water for much of your entry. A beach may look sandy from the shore, but concealed hazards could include sharp coral, rocks and rubbish, unexpected gullies and potholes and sea urchin beds. You need to find out how quickly a dive site drops off into deeper water, whether you should expect current once you reach back line, and the optimum time to dive in terms of weather conditions and tide. The best way to find the answers to these questions is to seek the advice of local dive centers or fellow divers who have experienced the site before. Failing that, tide charts, weather forecast stations, maps and guidebooks are all useful sources of information. How you choose to research your dive site is up to you — what’s important is that you do so.

Equipment considerations

When planning for a shore entry, you need to make sure that you have all the equipment necessary to protect yourself, especially in those areas with more challenging conditions or terrain. If you are making a shore entry from a beach with uneven or sharp ground (for example, loose rocks or exposed reef), you may want to ditch your closed-heel fins in favor of open-heel fins with thick-soled booties that will protect your feet. Similarly, while a shorty wetsuit may provide adequate protection when diving from calm beaches in the tropics, you may want to cover up with a full suit and even gloves when facing rougher conditions. In the event that you do get knocked over by a wave when entering the water, you will be glad of the added layer of neoprene protection. You also need to consider what additional equipment you take with you — is a dynamic surf zone really the best place for expensive camera housings and torches? When shore diving, it is important to remain relatively unburdened, with your hands free during entry. Anything you do take needs to be securely attached, or confined to a BCD pocket.

Preparing for entry

No matter how thoroughly you have researched a dive site, it is important to take a moment to assess conditions on the dive day. You may have been told to expect moderate surf, but if you arrive after a big wind, that same surf will pose a much greater hazard. Observe the waves, and decide whether they are manageable or not. If you decide that they are, watch the sets until a pattern emerges and then time your entry to coincide with the smaller waves. Watch for rip currents or concealed rocks, the former of which is often denoted by a line of sea foam traveling towards the horizon, the latter of which will cause the incoming waves to break irregularly as they pass over the rocks. Armed with this information, you can decide your best entry point; once decided, try to find a static reference point on the shore that corresponds with your place of entry so that you can use it to exit as well. When you are ready, it’s time to don your gear, making certain that all trailing equipment (including your gauges, alternate air source and pressure inflator) is securely fastened or tucked away. When preparing to make your entry, you should have all equipment in place, with the possible exception of your fins.

Taking the plunge

After all your preparation, it’s finally time to get into the water. You should have your mask on, and your regulator in place, in case you find yourself submerged earlier than expected. If there is no surf or it’s relatively calm, you can enter the water with your fins under your arm. Wade in until the water reaches chest level, then put your fins on and swim backwards with your BCD inflated until the water is deep enough to make your descent. You can also enter the water with your fins already in place, making sure to walk backwards to maintain your balance — it’s up to you. In extreme surf, you will need to execute your shore entry slightly differently. It’s a good idea to enter the water with your fins already in place to reduce the risk of losing them should you become overpowered by the waves. Walk into the water sideways in order to minimize the impact of oncoming waves on your body. As soon as you’re deep enough, let all air out of your BCD and descend to the bottom; there, you can use your hands to pull yourself to deeper water in coordination with the pull and lull of the waves crashing above you. When making a simple shore entry, it’s usually possible to maintain contact with your buddy, but in rougher conditions, it’s easy to become separated in the surf zone. For this reason, you may want to agree to surface upon reaching calmer water so that you can reconnect and orient yourself with the shore.

The keys to a successful shore entry are planning and preparation. Before attempting an entry of this kind, make sure that you have all the information you need to remain safe. Never hesitate to cancel a dive if you feel insufficiently prepared or if the conditions seem too challenging on a given day — as with all kinds of diving, there’s always tomorrow. If the conditions are right, however, tailor the tips in this article to the specifics of your chosen site, and prepare to discover for yourself the unique freedom of diving from the shore.

10 Tips for Night Dives at Moalboal: Well known dive Spot in Cebu

Posted by Chris White on Tue, Mar 19, 2013 @ 12:01 PM



Adapted from an article by John Brumm of Sport Diver magazine

Underwater night dive



Night diving is special because even a familiar site looks different at night. When you make a day dive, you normally scan the entire dive site looking at your surroundings. At night, you see only the area of the dive site that is lit by your light. This forces you to slow down and concentrate on that one area.

Tip #1
Stay close and shallow. Night dives tend to be shallow, so you’ll have plenty of bottom time to go slow and take it all in. Colours, for example, are much more vivid on a night dive than they are during the day. It’s simple dive physics. If you’re making a daytime dive in 66 feet of water, sunlight gets absorbed, stealing away the colours. On a night dive, your light source is never more than five or 10 feet away, so the water doesn’t take away any of the light spectrum.

Tip #2
Redefine “night.” When the sun is low in the sky, very little light penetrates the surface, making it pretty dark underwater, even when there is still a fair amount of light above. Diving at dusk is a good way to start your night-diving career. You have the convenience of gearing up when it is relatively light, but get the full effect of making a night dive. On ocean dusk dives, you also have the added benefit of watching the reef creatures migrate through a kind of “shift change” as the day animals disappear and the night animals come out to play.

Tip #3
Get the right gear. You’ll need a primary dive light and a backup light. The primary light should be the larger and brighter of the two. How large and how bright? That’s up to you, and your choice may vary depending on the clarity of the water. When shopping for a light, try out several as some have different grips and handles to suit your personal preferences. Your backup – or pocket – light should be small enough to stow easily, yet bright enough to help you find your way back home. Most lights designed for this purpose are smaller and typically shaped more like a traditional flashlight. Remember, though, that if the primary light fails and you switch to your backup, it’s time to end the dive. We are reviewing dive lights later this year, but for our 2012 Editor’s Pick for Best Dive light, read about the Sola Dive 500 

Tip #4
Tie one on. Most dive lights come with a way to attach a lanyard or wrist strap. Get one. It’s cheap insurance against dropping and losing your primary source of illumination. Most dive lights are negatively buoyant; if you drop one in deep water it may be gone forever.

Tip #5
Know the signals. If there’s one aspect of night diving that is more complicated than day diving, it's communication. You and your buddy should review hand signals before entering the water and agree on the ones you'll use. You have two options: One is to shine the light on your hands so your buddy can see what you’re saying. The other is to make signals using your light. You can signal “OK” and “Yes” or “No” by moving your light in a circle, or up and down, or side to side. You can even get your buddy’s attention by circling or “lassoing” his light beam and then pulling it toward you. If you’ve practiced this beforehand, your buddy will know what you’re doing.

Should you become separated from your buddy, get vertical and shine your light outward while turning a full circle. Your buddy should do the same and chances are you’ll spot each other. If you surface far from the dive boat, point your light at the boat until you get the crew’s attention, then shine it down on your head so the crew can see you clearly.

Tip #6
Aim carefully. On any night dive, you should treat your light like a loaded gun. Never shine your light directly into another diver’s eyes — you can ruin his night vision.

Tip #7
Go easy on the light. First-time night divers tend to buy the biggest, brightest beam they can find and cling to it like a security blanket. As you gain experience diving at night and get comfortable, you’ll find smaller primary dive lights do just as well, particularly in clear water. On some night dives, lights of other divers, the boat and the moon can provide so much ambient light that you may leave your torch off for much of the dive.

If you do need a light, you may not need its full power. Some LEDs have a half-power setting you can use to dial back the brightness. Or try dimming your light by cupping your fingers over it. In any case, you’ll see more natural behaviours if you use the edge of the pool of light, not the hot spot, to pick out fish and critters.

One of the unique things about night diving in the ocean is bioluminescence. Some varieties of single-celled plankton give off light when they are disturbed underwater. Your fin kicks or a wave of your hand can create an explosion of undersea sparks, but you’ll miss the show in anything but dark conditions.

Tip #8
Do reconnaissance. Before you make your first night dive on a site, you should dive it during the day. This allows you to learn the layout of the site and get comfortable with it. 

Tip #9
Mark the way home. If you’re diving from shore, rather than from a boat, you should also place lights on the beach. It's a good idea to have two lights close together at your entry/exit point and then a third farther away. This gives you something to swim for after the dive when you're swimming back in.

Making a night dive from a boat brings with it a different set of concerns. The boat should be marked with a flashing strobe you can use to find your way back. When surfacing near the boat, shine your light toward the surface and watch carefully to avoid colliding with the hull.

Tip #10
Have fun! Most important, relax and enjoy the dive. It’s natural to be a little anxious before stepping in the dark void of an unlit ocean or lake, but it’s also exciting. When you overcome your anxieties about night diving, you get another eight hours of each precious dive day to explore and create new and lasting dive memories.

What happens if you get separated from your buddy or the boat after finishing a night dive? There’s a reason why we recommend carrying at least two safety signalling devices when you are diving at night.
