40 Insider Tips For Dive Travel
Part 2 of 2
Experience is expensive, which goes along with the old adage that an expert is just a person who's made every mistake possible in a very narrow field. Whether you're approaching expert status in the world of dive travel, or you're just hoping to lessen the cost, we offer these tips on getting the most out of your diving vacation. 21. Wear sunscreen beginning on the first day. A sunburn in paradise is no fun. 22. If the divemaster sets up your gear, check it before the dive. 23. Stash a pen in your carryon for filling out immigration forms. 24. If you're traveling with new dive gear, give it a test run in a swimming pool or watering hole before the trip. 25. Dive suits have a way of shrinking, especially over the holidays. Make sure yours still fits. 26. Keep a protein bar and bottle of water in your carryon to stave off hunger pangs. 27. Flying to the other side of the world? Stay up as late as possible the night before leaving to lessen jet lag. 28. Baby powder. You'll know what it's for when you need it. 29. Keep a firm grip on your luggage upon arrival, not because of crime, but because island cab drivers can be very aggressive in soliciting your business. 30. Get some cash changed into the local currency at the beginning of your trip, even if credit cards and gringo bills are widely accepted. It's great for tipping and light souvenir shopping. 31. A bottle of the pink stuff can be worth its weight in gold. 32. Forget to log a dive? Check with your boat crew or dive shop, they can verify site names, dive depths and the name of that funny little fish with the thingy on its head. 33. Full-foot fins, even ones that fit like a glove, can cause blisters after several days of hard diving. A simple pair of socks will help. 34. If you rent a car, first find out what the terms of the agreement are and what the local regulations are (do you need a special driver's license? is the driving on the opposite side of the road? do you need to return the car with a full tank of gas?) 35. Stay healthy by washing your hands the same way you clear your ears on a dive: early and often. 36. If you have a sensitive tummy, beware of ice cubes made from the local water supply. 37. Smile. You're on vacation! 38. Slip-on deck shoes or Teva-style sandals are better than flip-flops for a week on a liveaboard. 39. Sometimes a bad movie is better than a boring flight.40. Hardworking dive crews appreciate verbal praise, but a good tip is worth a thousand words.

Whether you're approaching expert status in the world of dive travel, or you're just hoping to lessen the cost, we offer these tips on getting the most out of your diving vacation. 1. Don't overstuff your bags — you'll need room for souvenirs.
2. Place fins along the edges or top of your dive bag's main compartment to protect your other
3. Koozies rule! Foam drink holders make great protective sleeves for dive computers.
4. Protect your mask by storing it in an open-heel fin pocket. 5. For added cusion, pack wetsuits around regulators and other sensitive equipment.
6. Don't forget to pack a few save-a-dive tools, like a crescent wrench and Allen keys.
7. WD-40 or similar lubricant is great for cleaning up bag wheels, dive knives and other items that corrode.
8. Backup gear is great, but do you really need an extra set of booties? 9. A new mask will only work if you remember to clean it thoroughly before the trip. 10. Avoid checking luggage with huge dive flags and other obvious diver insignia emblazoned on it. There's no need to advertise. 11. Get insurance.
12. Answer the airline staff's questions patiently and with a smile — they just want to make sure your pony bottle isn't an incendiary device.
13. Weight limits are stricter than ever. Take the time to weigh your bags before you go.
14. Keep a few heavier items (like dive lights) easily accessible so you can move them from one bag to another if you don't make weight.
15. Dive bags are heavy, so tip the sky cap well.
16. A smile goes a long way with customs and immigration officials.
17. Liveaboard divers often take two wetsuits so they always have a dry one to slip into.18. Batteries, batteries, batteries. 19. Sudafed or another decongestant can help you on the flight home if your sinuses act up. 20. Dress in layers and keep it cool. Island airports and other facilities are not always air-conditioned.
GoPro Underwater Photography Guide
Article by Thomas Gronfeldt
Housing, Filters and Hardware
The wildly popular GoPro camera seems ubiquitous these days, having made its way into most active sports from surfing to mountain biking to rock climbing, and, of course, to scuba diving. And for good reason: the small cameras deliver high quality, full-HD footage in a travel-friendly, fairly inexpensive package.
However, as most people who’ve bought one have discovered, buying the camera is only half the battle. Learning to use it, along with purchasing a range of extra accessories, will help you get the best footage possible during your sport of choice. In this article series, we’ll cover all you need to know to make your GoPro into a lean, mean, dive footage-creating machine.
First and foremost we must look at the housing. The original GoPros came with a durable housing, rated to 60 meters (197 feet). It was somewhat large and cumbersome, though, and had a few diving-related problems, such as a moderate wide-angle effect intended for land-based shooting. GoPro subsequently redesigned their housing and camera to be smaller, lighter and more suited to diving. The current version, the GoPro Hero3+, features a much slimmer housing, but it’s only rated for 40 meters (131 feet). GoPro has also produced a separate, dive-specific housing, rated to 60 meters. Although recreational dive limits top out at 40 meters, because of the difference in dynamic and static pressure, it’s recommended that if you routinely dive to 60 feet or deeper (18 meters+), you get the dive-specific housing to reduce the risk of flooding. The good news about the new version is that the wide-angle capabilities are much better than on previous versions, allowing divers to move very close to the motif of the photo, while still capturing all of, say, a reef shark. We’ll get into shooting practices in a later article.
Light starts to fade away as we descend, but we don’t lose light equally across the spectrum. Normal light contains all the primary colors, which fade away one by one as we get deeper. The first to go is red; the last is blue. Because of this, underwater photography and film footage often seems blue, a tendency that increases the deeper we go. To remedy this effect, a red filter is a highly useful for underwater photography. There are filters for all types of cameras, including the GoPro. Some filters simply click on over the lens; other, multiple filters allow divers to switch between them on a multilevel dive. The latter configuration makes it possible to account for the lighting conditions at any given depth, but these filters are typically more expensive and bulkier, and determining which filter goes with which depth takes some training. Other filters are made for specific lighting conditions, such as the greenish hue of freshwater, or for night diving. In any case, a red filter will greatly enhance your photos, and along with a photo light, make the colors and details pop, ending the age of blue or green dive photos.
Photo and video lights
Which brings us to lights. Again, light disappears as we descend, and while compensating for this with a filter is important, so too can be compensating for the general loss of light. Powerful photo and/or video lights can help. Think of photo lights as underwater flashes that shoot off a burst of light as you take a picture, helping to illuminate the scene. Video lights are more like flashlights or dive torches that shine continuously, illuminating the scene as you film. When using either, instead of being directly beneath or directly above the lens — as in a traditional camera flash — it helps to put the light at an angle to help reduce backscatter. Our next article will cover more on light placement and mounting options.
In its most basic configuration, the GoPro works pretty well as an underwater camera, in particular for snorkeling and shallow dives. But to take it up a notch, requires a little more of an investment, including lights, filters, and possibly a dedicated dive housing. With these, you’re ready to take your underwater photo and video to the next level.
The Philippines – a photographer’s dream
Posted by Andrew Jenkins
The Philippines is a photographer’s dream. The astounding landscape both topside and underwater glistens with colour and is calling out to be explored.
Start your adventure by passing through Manila, Philippines manic capital, perhaps stopping to take a ride on a rainbow coloured Jeepney – a kitsch vehicle that is one of the most popular forms of transport in this busy city. Once out of the city hub the variety that exudes within this tropical archipelago is hard to look past.
A perfect destination for scuba divers of all experience levels, the Philippines is in the heart of the coral triangle and is world renowned for nutrient rich currents and consequently some of the world’s most fascinating marine life.
Below are some fantastic diving locations to visit when traveling the Philippines:
- Cebu: placed neatly in the centre of the Visayan Archipelago, Cebu is a great place to learn to dive. With the second largest airport in the Philippines, it is easy to access and has a great range of dive sites. It is not uncommon to spot green turtles, giant frogfish and banded sea krait.
- Bohol: growing increasingly popular with backpackers visiting Panglao Island, Bohol is about an hour plane ride from Manila and usually offers a divers the opportunity of spotting huge schools of jacks. Colourful coral of hard and soft varieties make diving off Bohol a rainbow adventure you’re sure to love. The topside is also well known for the Chocolate Hills and the tiny Tarsier monkeys.
- Malapascua: this is an island that cannot be missed. Malapascua is one of the only places in the world where you’re almost guaranteed daily sightings of the rare and fascinating Thresher shark.
- Boracay: it is here that you’re likely to see grey reef sharks, manta rays and a plethora of tropical fish that inhabit the large assortment of corals. This is the most popular holiday destination.
- Subic Bay: this world renowned wreck diving destination is home to a plethora of historical stories that even the most advanced divers are sure to be impressed by.
- Tubbataha Reef: Although this reef is only accessible for three months of the year (March- June), this World Heritage Marine Park is well worth the visit. Accessing this area by liveaboard is the only option but the pristine corals which are populated with intriguing macro life, turtles and a wealth of tropical fish make this location a real gem.
- Puerto Galera: Ideal for those interested in drift diving, these current rich waters are imbued with snapper, barracudas and smaller tropical fish. There is the opportunity to do a night dive and potentially see the gorgeous Mandarin fish. Puerto Galera is based at the Verde Strait, which has the some of the world’s greatest biodiversity.
- Dumaguete: here you can experience the magnificent beach dives that macro enthusiasts are sure to love. In the deeper waters, the strong current often brings large schools of big-eye trevally and Spanish mackerel.
- El Nido and Coron in Palawan: There is no denying that Palawan is a picturesque tropical paradise. The topside is decorated with the most magnificent lime stone cliffs, and below the crystal clear horizon is the awe-inspiring wrecks in Coron and a range of tropic fish off El Nido.
What You Should Never Do on a Dive
The golden rules of what NOT to do while scuba diving. Use common sense & scuba training to have fun and stay safe.
Never Not Have A Plan
Do your research. Plan your dive & dive your plan. Agree with your buddy on depth, time, safety stops & minimum air before you head to the exit point. Check your equipment! Don't Be Sick
Including hangovers. You'll want as much energy as possible to dive & you'll want to stay hydrated. Eat at least 2 hours before hand & drink plenty of water. Take sea sickness pills to build immunity. Do Not Go Outside Your Comfort Level
This isn't some reverse psychology ploy. If you feel uncomfortable diving that deep, DON'T DO IT. Stay within your comfort level, skill & training. Otherwise, you could panic and get hurt. Never Hold Your Breath
When you descend the pressure on your lungs increases & your lung volume decreases, it's the opposite for ascending. A diver who holds his breath underwater seals off his lungs, severely hurting them. Never Go Alone
Use the buddy system; one person below, one above and yourself. It can be incredibly dangerous (and difficult) to dive by yourself. If you are certified, bring another certified friend. Don't Buddy Breath
Unless you and a buddy have practiced breathing from a single regulator, do not do it. Typically, one of you will forget to control your buoyancy. Proceed with Bad Weather
Ask around about weather & conditions the morning of. Err on the side of caution: if it's too rough and it could lead to a dangerous situation, don't go.
Nitrox For Beginners
By Jessica Vyvyan-Robinson
Although nitrox has been used for recreational diving for almost 25 years, it is still often misunderstood. As an instructor, I’ve found myself correcting countless students who are under the impression that nitrox enables a person to dive deeper than normal air — just one of the common misconceptions about nitrox diving. Although specific training is required before diving nitrox for the first time, these basic facts will help to make more sense of what it is and what it can do for you.
What Is It?
Quite literally, nitrox refers to a mix of nitrogen and oxygen, regardless of the percentage of each in the mix. The nitrox we use while diving is more properly called enriched-air nitrox, and refers to any blend of nitrogen and oxygen in which the oxygen concentration is greater than that of normal air. This means an oxygen level of 22 percent or higher, although the most common enriched-air nitrox blend is 32 percent. The recreational diving limit is 40 percent oxygen.
What Does It Do?
As every entry-level diver knows, increased pressure at depth causes the nitrogen in the air we breathe to be dissolved into the bloodstream. The time that we can spend underwater is limited by this nitrogen absorption — as we dive deeper and for longer, we absorb more nitrogen at a greater rate. Our no-decompression limit correlates to the amount of nitrogen our bodies can absorb before we must perform compulsory decompression stops or suffer the consequences of decompression sickness.
Enriched-air nitrox slows down the rate at which nitrogen dissolves into our bloodstream, because there is less nitrogen available to be absorbed from the mix that we’re breathing. The higher the percentage of your enriched-air blend, the more nitrogen is replaced with extra oxygen.
There are several reasons divers use enriched-air nitrox. One of its biggest benefits is an increased no-decompression limit, which means longer bottom time. The lower percentage of nitrogen in the nitrox you’re breathing means your bloodstream is also absorbing nitrogen more slowly. For example, on normal air a diver has a no-decompression limit of 50 minutes at 60 feet; using a 36 percent enriched-air mix at the same depth will extend this limit to 130 minutes. In terms of increasing bottom time, enriched air is most useful for depths between 50 and 100 feet; any shallower and no-decompression limits are already so long that divers usually have no need to extend them.
Surface intervals are usually shorter on nitrox as well. Since there is less nitrogen to off-gas, a diver on enriched air will be able to re-enter the water sooner than a diver using normal air after completing the same profile. This also means that divers using enriched air typically have longer maximum bottom times on repetitive dives, and less off-gassing means that enriched air divers are often less tired at the end of the day than divers using normal air. Enriched air can be a valuable safety buffer for divers who choose to use it while following normal air tables, computers, profiles and procedures. Doing so creates a considerable conservative margin that further reduces the risk of decompression sickness, and may be advisable for anyone who may be susceptible to it, such as those who are tired, overweight, older, have suffered decompression sickness before, or are diving with injuries.
Myths, Considerations and Dangers
Although the benefits of diving with enriched air are significant, doing so also involves certain risks. One of the most common misconceptions about enriched air nitrox is that users can dive deeper than with normal air; in fact the opposite is true. Under pressure, oxygen becomes toxic. The percentage of oxygen in normal air (21 percent) only becomes toxic at depths greater than the recreational limit, but the increased percentages of oxygen in enriched air mean that toxicity can become a problem at much shallower depths. Toxicity causes convulsions that put a diver at risk of losing his regulator and subsequently drowning. However, enriched-air courses teach divers how to work out their maximum operating depth using the percentage and partial pressure of the oxygen in their mix. As long as the maximum operating depth is adhered to, oxygen toxicity should not be a problem.
Oxygen also requires caution in the sense that it is an exceptionally flammable gas. Although standard scuba equipment is safe to use with air blends containing up to 40 percent oxygen, the process by which an enriched-air cylinder is filled often involves much higher concentrations. Partial-pressure blending exposes the cylinder to pure oxygen that is later diluted with normal air, and cylinders that are not treated for exposure to such high levels of oxygen can explode. Therefore, any part of the cylinder that comes in to contact with pure oxygen needs to be “oxygen clean,” and cylinders used for enriched air and normal air are not interchangeable. Enriched-air cylinders require decals or stickers to differentiate them from normal ones; they should be serviced annually.
There are a few other equipment considerations to bear in mind when considering enriched-air diving. Before each dive, you are personally responsible for checking the percentage of oxygen in your cylinder. If it is even slightly off, your maximum-operating depth calculations will be too. To check, you will need an analyzer, and although you can usually borrow one from your dive center, it’s a good idea to have your own if you intend to dive nitrox regularly. If you dive with a computer, you need to make sure that yours has enriched-air settings and correlates to the details of your mix before beginning each dive. Remember that enriched air does not improve air consumption, and neither does it give immunity to decompression sickness. Continue to check your gauges, depth and time limits as often as you would when diving on normal air.
With these precautions and the necessary training, enriched-air diving is a fantastic way to get the most out of your diving experience. You’ll spend more time in the water, and less time waiting to get back in.
8 Ways to Increase Your Diving Confidence.
By Polly Philipson
Many people feel anxious before a dive when they are starting out on their scuba diving journey. It is completely understandable as it is a new realm that is being explored. Beginners don’t know what it is going to feel like underwater or if they will enjoy it. It feels like there are so many things to think about to start with. These tips help build confidence that will assist you prepare for your amazing underwater experiences
1 – Professional Training Builds Your Diving Confidence
Years of research and tried and tested techniques have gone into formulating today’s scuba diving courses. Modern scuba diving training has been specifically designed to alleviate stress and slowly build on skills to a point where divers are ready to go out into open water. Organizations, such as PADI, have skills and procedures that divers must learn in sequence – these standards are adhered to by PADI Instructors worldwide. Studying theory, watching videos and learning skills in the pool is followed by practicing in the sea with your instructor. This allows you to slowly develop at your own pace – only progressing when you are comfortable with each section.
2 – Knowing Your Equipment Increases Diving Confidence
During your scuba diving training, you will learn how to set up, adjust, check, and don your equipment. Understanding how your equipment works will give you added confidence and alleviate stress. Making sure everything is fitted correctly and securely, with the help of your instructor or buddy, is very important.
3 – Confined Water Practice Raises Diving Confidence
As mentioned earlier, your training is performance-based, and you will have ample time to learn and practice scuba diving skills in the pool before heading out to the open water. Your instructor will assess your capabilities and allow extra time for practice if needed. Likewise, if you haven’t dived for a while then it’s a great idea to jump back into the pool for a Scuba Review.
4 – Correct Weighting and Buoyancy Assist Diving Confidence
Divers perform weight checks on the surface before a dive to determine that they have the correct amount of weight. You will be taught this during your training. If you are worried when you start your open water dive that you may be under weighted, then ask the instructor to carry spares or have spare weights available at the end of the dive on a descent line. It is a mistake to overweight yourself, as this will make you consume air faster and alter your buoyancy and trim when underwater.
5 – Breathing Techniques Help Diving Confidence
Begin your dive relaxed and calm – give yourself time at the start of the dive to become relaxed with slow, deep breathing. Allow yourself to orientate to being underwater by pausing after your descent. Take time to regulate your breathing, check your equipment and computer, and to signal to your buddy that everything is OK. Then you can focus on having fun and discovering the amazing marine life!
6 – Discuss Diving Confidence
Build your confidence by talking to your instructor and other divers about their experiences. You will find people’s passion and love for the sport is infectious; divers love to share their underwater adventures and knowledge. If you feel nervous before a dive then talk to your instructor or buddy. They will assist you in identifying what is causing your nerves and help you to solve any issues.
7 – Watching Videos
Training agencies such as PADI have videos that complement their courses. They are a great way to see what it is like underwater before you go! Watching videos will prepare you for your first experience by visually demonstrating the theory you have learned. Popular online sites such as YouTube are a good resource for finding footage of various dive sites and marine life.
8 – Relax and Enjoy!
The final piece of advice is to relax, take your time and enjoy. Don’t rush to set up your equipment and work at your own pace when getting ready for your dive. When you rush, you create stress and may not follow the procedures you have been taught. Similarly, don’t rush around underwater – take time to appreciate what nature has created and enjoy the full experience of breathing underwater.
Can Scuba Be a Good Workout?
By Jessica Vyvyan-Robinson
Although scuba is technically a sport, for most of us, diving is more about calm than cardio. One of scuba’s biggest attractions is the relaxation it offers, as well as the chance to escape from the frenetic pace of life on land. Most dives require very little physical work once underwater, and so it’s hard to think of scuba as part of a fitness regime. But a day of diving always leads to a good night’s sleep and a disproportionately large appetite, so perhaps we’re expending more energy underwater than we realize. Although diving requires a relatively low level of physical activity, other factors combine to make it effective exercise, which is good news for those of us who would rather spend our time beneath the waves than in the gym.
The conditions of the underwater environment are a considerable factor in scuba’s value as a fitness tool. Although you may not feel as though you’re exercising while diving, the water around you is conducting heat from your body 20 times faster than air, so you must work hard to maintain its core temperature. Even in tropical climates, metabolic activity increases significantly in order to combat heat loss; in cooler parts of the world, the body must expend even more energy to counteract frigid temperatures at depth. Some dives require more physical activity than others — anyone who’s ever had to contend with strong current knows just how tiring swimming against the flow can be. Similarly, keeping up with marine life, attempting to stay in one place for photography purposes, or any kind of underwater activity that involves hard finning results in additional calorie expenditure.
The technique used to fin properly, i.e. from the hip rather than from the knee, is key to strengthening core muscles as well as glute and back muscles, according to PADI’s director of communications Theresa Kaplan. She attributes diving’s toning and strengthening properties to the fact that water is a medium “hundreds of times more dense than air.” Water resistance is instrumental in defining scuba as a valuable form of low-impact exercise. Diving’s low impact also makes it a good alternative to conventional exercise for those with weak or injured joints, as it puts considerably less strain on the body than most land-based physical activities. Diving is therefore not only a good workout for healthy individuals, but also a great form of physical therapy for those recovering from injury. Some scientists even believe that scuba may decrease the time it takes for wounds to heal, thanks to the body’s consumption of concentrated levels of oxygen at depth.
Diving can also aid long-term fitness, as breathing techniques used to improve air consumption teach the body to absorb more oxygen for every inhale. Normally, the body uses only a quarter of the oxygen it inhales, but diving can increase lung efficiency over time. And the dive itself isn’t the only part of the sport that offers a workout. The routine of kitting up, carrying gear to the point of entry, getting in and out of the water and de-kitting also contributes to scuba’s overall fitness value. A dive cylinder weighs between 30 and 50 pounds; carrying a full scuba unit strengthens core muscles, particularly during shore entries. Lifting cylinders, weights and other equipment often involves actions comparable to weight-lifting exercises used in the gym. Diving is therefore not only a cardiovascular workout but a muscular one as well. According to the American College of Sports Medicine, the physical demands of diving are significant enough to be treated with caution; those suffer from significant health conditions or obesity should seek medical advice before attempting to dive.
The benefits of scuba to general physical fitness were acknowledged by the 2011 Compendium of Physical Activities, which compared it in terms of metabolic activity with ice-skating, power-walking and casual soccer. On average, a man weighing 180 pounds can expect to burn as many as 600 calories during an hour dive, and many more if swimming in strong currents or particularly cold water. Several online calculators can work out the calories burned during a specific dive, based on weight and the time spent underwater.
Scuba is beneficial not only as a viable form of physical exercise, but also for mental and emotional wellbeing. The peace, serenity and beauty of the underwater world encourage positivity and give real joy to those who experience them. Diving is a great way to tone and strengthen your body, burn calories and boost your serotonin levels, ultimately making it both a rewarding and enjoyable way to keep fit.
