Before you make a decision about buying certain dive computer, let's answer some common questions about it. In this article you will find basic and general information about these devices and this will help you on the way of choosing the "right one".

Basically, dive computer is a device that monitors and shows you depth, Elapsed Dive Time, temperature, No-Decompression Dive Time Remaining, nitrogen and oxygen loading, and many other things, depending on the model you use, dive mode, and whether you are diving or on surface.

But the main task of the dive computer – is to calculate the nitrogen loading and oxygen toxicity levels and compute the most optimal and the safest surfacing procedure, manage decompression, and the surface interval between the dives. In shorter words – it helps us staying out from getting into the Decompression Sickness as long as we obey safety rules, warnings and alarms.

It simplifies our diving by replacing Dive Planners and Wheels (but it is still a good idea to keep RDP or Wheel as a backup)!

I can mention that all dive computers produced in following mounting options:

computer consoles (Aeris Atmos ai, Mares Puck Air, Suunto Cobra);
wrist dive computers (Oceanic OC1, Cressi Archimede 2, Tusa IQ-950 Zen Air);
wrist units (Mares Icon HD, Uwatec Galileo Sol, Tusa IQ-850 Sapience);
scuba masks (Aeris CompuMask, Oceanic DataMask)

When you dive and go deeper - your safe dive time is decreasing. And if you exceeded No-Decompression Limits (NDLs) – dive computer activates Decompression mode. At that moment you will see the nearest decompression stop depth and decompression time are displayed.

Dive computer constantly monitors our nitrogen loading and oxygen toxicity level and it may give us a warning or alarm if levels come close to certain maximum allowed.

And, as well, if our ascent rate is faster than it should be – dive computer will activate Ascent Rate alarm in order for us to slow the ascent.

When we are on surface, in order to make another dive, we have to calculate the nitrogen loading level of our organisms by using Recreational Dive Planner, but if we have a computer - we just need to follow its recommendations. It will help us to perform this task by counting Desaturation Time and No-Fly Time as well.

Many modern scuba dive computers have possibility of downloading your diving history into the computer, using USB or infrared interface and special software. And you may even download from your PC into the dive computer coloured or grey-scale bitmap pictures (Mares Icon HD, Uwatec Galileo Sol and Galileo Luna)!

Depending on the model of the dive computer, you may have following dive modes:

Air;
Nitrox:
Gauge;
FREEdive

Some of the scuba dive computers may be programmed for up to 3 gas mixes and with possibility of switching between them during a single dive, and dive computer HelO2 by Suunto, may be programmed for up to 8 gas mixes, and can be used for diving with Air, Nitrox, and Trimix.

Next feature is the air-integration. You will meet three options here:

hose air-integrated dive computer;
hoseless air-integrated dive computer;
dive computer without air integration

With hoseless (wireless) air integration you need to have a transmitter installed on the regulator. Many of hoseless air-integrated models have Buddy Pressure Check feature, which means that you may check air pressure of your 'buddy' using your own dive computer if your buddy's transmitter is correctly paired with your computer.

Another important feature is compensation for Altitude diving. Many dive computers these days automatically compensate for altitude diving and give you adjusted no-decompression times and depths, according to your current altitude. In some models you may set up manually altitude in certain ranges, like in Suunto and Mares brands.

It is worth to mention here Personal Conservative Factor adjustment. Just as an example – if Aeris dive computers allow us to set this factor just to ON/OFF state, Mares and Suunto models give us possibility to increase or decrease level of conservatism by choosing between highest and lowest levels. And this gives us possibility to set our computer for either liberal or conservative diving.

These days majority of dive computers are made with the diver replaceable battery option, and some of them have 'hot swap' feature, which means that you need to replace battery within 8 seconds in order to keep nitrogen and oxygen calculations for next dives and other data stored in dive computer, like some settings, for example.

When you will be doing research to get the dive computer that is the best for you – go for one, which has ‘diver replaceable battery' option. It will save you time and money, and also you will be able to continue your diving adventure without any interruptions.

Some of the models, like Oceanic OC1, Tusa IQ-900, Tusa IQ-950, UWATEC Galileo Luna, UWATEC Galileo SOL and few others have Data Retention function, which means that we may replace the battery at any time between the dives, without losing any nitrogen or oxygen calculations, because all data is stored indefinitely.

So, as a conclusion, all of those features, significant or not very, as you may think of them, have only one the most important benefit for us – keep us on the safe side and avoid Decompression Sickness (DCS).

Know How Your Dive Computer Works Inside Out

Scuba Diving in Thailand has many rewards for Recreational Scuba Divers, and world class dive sites in Phuket and the Similan/Surin islands are recognised for their vibrant marine life, nutrient-rich coral reefs and clear blue, warm water. Adventurous tourists flocked to Thailand in search of palm fringed golden sand beaches, luxurious beachside accommodation, endless watersports and countless family activities, value for money that few tourists to Asia could resist. Late December 2004 saw an event that would scar the lives of so many people and my account of this tragedy is based on what happened on the Andaman Coast of Thailand, though I fully appreciate that other countries and continents were also affected.

In Thailand, more than 8,000 people were killed in the disaster, or have never been reunited with their families. This also included over 2,000 foreign tourists, most of which were taking holidays in and around Phuket. This southern province contributed approximately 40 percent of Thailand's annual tourism income. The Indian Ocean tsunami was triggered by an undersea earthquake off the Indonesian island of Sumatra, and as the huge waves of tumbling water struck the Andaman shores, Phuket and its surrounding regions suffered raw nature at its worst. Phuket Scuba Divers who were actually under water at the time, recall a surge of water that pushed and pulled with all its might. Dive Boats were smashed, snorkelers were dragged along the beaches, and sunbathers were completely overwhelmed by a wall of water crashing overhead.

As you may expect, tourism in this region suffered tremendously, and has not yet fully recovered. Scuba Divers in Thailand are trying other diving destinations and during the last five years,  Scuba Diving in Pattaya  has seen a positive increase in the number of divers making a trip to dive in the Gulf of Thailand. The Pattaya Scuba Diving community are united in their efforts to attract more tourists and also to satisfy its expanding number of residing expats. The islands near to Pattaya offer divers and snorkelers a mixture of shallow calm bays sheltered from the strong currents, to deep dives around World War II US Landing Crafts that have been intentionally sunk by the Thai Navy, creating artificial reefs. Most of the Pattaya Dive Sites can be reached by a dive boat withing two hours and there are many PADI Dive Centers that offer daily Scuba Courses for beginners, Fun Diving Daytrips for certified divers and Snorkeling Tours for a relaxing day out to the Pattaya Islands.

Information, tips and advice for Scuba Diving in Pattaya

Most of the Pattaya dive sites have year-round diving and a good variety of diverse dive sites. From shallow coral dives to wreck diving, deep diving and drift diving, there are numerous scuba activities that can entertain beginners and even the most experienced scuba divers. The Pattaya Near Islands include Koh Sak, Koh Larn and Koh Khrok. Koh Larn means "Coral Island" in Thai, and the Thai's feel that Koh Sak and Koh Khrok resemble a mortar and pestle, so they named them after the kitchen tools that they use to crush peppers. The Pattaya Far Islands include Koh Rin, Koh Man Wichai and Koh Phai. Because these island dive sites are around 15 km from Pattaya, they tend to be less crowded by dive boats and water sport activities. The boat trip takes about 90 minutes to get there, but the clearer visibility and the vibrant marine life makes these Pattaya dive sites worth the trip.

Pattaya 'near' islands;
Koh Sak - A sheltered, shallow bay, which makes this dive site ideal for beginners, novice divers, and snorkeling in Pattaya. The maximium depth is around 11 meters, with lots of hard coral formations providing a home to Rabbitfish, Butterflyfish, Octopus, Morays, Stingrays, Wrasse, Angelfish and Damselfish.
Koh Larn - The Golden Bay on the western side of Koh Larn provides a variety of dive sites for divers of all levels. With hard and soft corals extending to 20 meters, this dive site is best known for spotting Tawny Nurse Sharks and blue spotted Rays.
Koh Khrok - A finger shaped island that is suitable for drift diving. Maximum depth reaches around 12 meters, with an abundance of sea anemones, clown fish, nudibranchs, and turtles.

Pattaya 'far' islands;
Koh Rin - Koh Rin has many diving areas, including two small satelite islands called North Rock and South Rock. With an abundance of hard and soft corals, coral whips and feather stars, divers will not be disappointed with the aquatic creatures on view around these dive sites. The dive needn't be deep here to see nudibranchs, sharks, razorfish, pipefish and morays.
Koh Man Wichai - Dives around this dive site in Pattaya can stretch down to 25 meters. There are two main dive sites, one being the 'Wall Dive' and the other being the 'Fingers'. Both areas provide a variety of corals including staghorn coral table corals, and here's where you're most likely to see larger fish such as Baraccuda, while you're in Pattaya diving.
Koh Phai - The beaches of this island are restricted because it is controlled by the Royal Thai Navy. The south of the island provides the best diving, with the small sheltered bay offering ideal conditions for beginner divers and those refreshing their dive skills. Close to Koh Phai is the wreck of the HTMS Khram, a WW II landing craft that was sunk in 2003 to create an artificial reef and a dive site for wreck diving.

Information about Wreck Diving in Pattaya

HTMS Khram Wreck - Early in 2003, the Thai Navy sank a decommissioned U.S. Warship between Koh Phai and Koh Larn island approx 15 km from Pattaya. The ship lies in 30 meters of water in the Gulf of Thailand, and was intentionally sunk to provide a breeding ground for fish, and a wreck dive for scuba divers. The Thai Navy prepared the ship as a dive site, and it is free from arms, oil and most of the other hazards to divers. The large holes that were made in many areas allow penetration dives through the ships passages whilst remaining in natural daylight. The wreck dive is a scuba diving gift for fish lovers', with Baraccuda, Trevallys, Jacks, Fuseliers, Batfish, Turtles, Stonefish, Porcupinefish, Unicorn fish and Sharks to name just a few.
HTMS Kood Wreck - Thailand dive sites are diving gifts for all divers, but wreck diving in Pattaya is 'nautical' miles ahead ! In September 2006, the Royal Thai Navy sunk the HTMS Kood a short 45 minute boat trip from Pattaya Beach. The Kood World War II US landing craft, became the nearest wreck to Pattaya, available for recreational divers with a diving certification above entry level. A sister ship of the HTMS Khram, the Kood is another fine example of a thriving artificial reef offering another great dive site in Pattaya. Just to the northeast of Koh Sak, the bottom of the wreck lies at 30 meters and the top of the tower at 12m.
Hardeep Wreck - Originally an Indonesian-registered freighter, the Hardeep sank in 1943. More than sixty years of growth has seen the soft coral formations and tube sponge gardens firmly establish themselves, and the wreck provides a safe home for older and larger fish families. The fish life on the Hardeep Wreck includes Baraccuda, Angelfish, Jacks, Trevellys, Batfish and Butterflyfish. Laying on its starboard side in 27 meters of depth, the wreck is only 42 meters in length and contains some very large openings to allow divers a view of the engine room and crankshaft.
Bremen Wreck - The Bremen is an 88 metre long Thai cargo ship that sank in the 1930's following an engine room explosion. The wreck now lies on the sandy bottom in 22 meters between Sattahip and Koh Khram. Though the wreck is badly broken, the bow and stern sections are still relatively intact, but the center part is mostly mangled steel. Wreck Penetration is generally not recommended on this dive. Though the currents can be strong here, if you plan your dive appropriately, the highlight of wreck diving the Bremen, is trying to spot the large Eagle Rays that thrive in these waters. The Bremen Wreck is situated in open water and experiences strong currents for much of the year. The optimum time to dive the Bremen is from December to March.

Pattaya, as a diving destination, cannot realistically compete with the natural underwater beauty of the pristine coral reefs of Phuket, but its aim for the near future is to attract scuba divers by hosting a special wreck diving region, having up to 5 new wrecks in the Pattaya diving area and helping to conserve and improve its marine environment. These artificial reefs provide a home for new coral formations and aquatic life, with the added bonus of being 'off limits' to the local fishermen which encourages larger fish to inhabit the wrecks. As Thailand continues to recover from the tragedy five years on, there's little physical evidence of one of history's worst natural disasters, other than an occasional Tsunami 'Hazard Zone' sign. Phuket remains one of Asia's premier holiday resort islands, and although tourism is down, few people blame the tsunami.

Tourism is down ..... but is it because of the global economy ?

If you're checking to see if it's legal, and how you plan to punish me, please allow me to explain. I'm a PADI Master Instructor of Scuba Diving, and I spend my working days teaching scuba in Thailand. One of the most rewarding experiences for my diving students' is shooting great photographs of aquatic marine life.

Making underwater photographs in Thailand has many advantages for divers searching for that 'perfect shot';

Clear blue water
Warm water averaging 28 degrees centigrade
Pristine Coral Reef formations
Established Diving Centers and Scuba Equipment Shops

 
The most popular tourist areas for scuba diving in Thailand are Pattaya, Phuket and Koh Samui. These resorts offer great fun and excitement for beginners and certified divers. Whether it's vibrant fish life, colourful corals or sunken ship wrecks, the camera won't stop clicking while you're scuba diving in Thailand. I've captured pictures of Seahorses and giant Gorgonian Sea Fans in Phuket, Black tip reef Sharks in Koh Samui, and World War 11 ship wrecks in Pattaya.

Todays modern camera equipment has changed the way that scuba divers 'shoot' fish underwater. The traditional film camera is still used by many diving professionals, but digital underwater cameras have made underwater photography both accessible and affordable to the majority of scuba divers. Learning to Scuba Dive is not difficult for most people who are comfortable in the water, but snapping great photos under water takes novices some time to learn. One of the most important attributes is good buoyancy control. Apart from all the obvious advantages that neutral, relaxed buoyancy has for scuba diving, if you're trying to compose that image of the tiny yellow blob, commonly known as a Frogfish, being able to hover almost motionless just centimetres away from your subject is what sets you apart from the norm. Also, as recreational scuba divers descend, water absorbs colour. Starting with Red, Orange and then Yellow, and as you dive deeper, you'll lose Green and Blue. Strobe lights help to restore some of the colour that's lost, which is how the professionals obtain fantastic vibrant colours from their images.

I fully appreciate that not every diver has a passion for taking pictures of the new world that they've discovered. Many divers are more fascinated by ship wrecks, perhaps diving deep or making dives using nitrox (an increased amount of oxygen) but most of my scuba buddies have admitted that they are very keen to share the wonders on the underwater world by shooting pictures of fish and other marine life. With modern technology as a friend, it's now possible to store and share underwater images with your family, friends and even the general public via social sites and the internet. The dive may have been the most amazing experience that you've had, but it's so much more powerful to share the adventures with those for whom it may not be possibly to try scuba diving. PADI scuba courses teach student divers how to capture and share underwater photographs, and the Digital Underwater Photography course is now available to all scuba divers from the age of ten.

Private scuba lessons are becoming more popular now, especially in Thailand. Taking a dive course with you own private scuba instructor offers exclusivity, the personal touch, and usually more flexibility. So to enrol in the shooting fish course, otherwise known as the PADI DUP (digital underwater photography) course, you do need to be a certified diver of at least ten years old. But be prepared for some underwater fun that diving in Pattaya has to offer. The coral reefs are shallower here than other dive sites in Thailand, and the other advantage is that scuba diving in Pattaya is available year round because the Gulf of Thailand tends to be sheltered from the southwest monsoons that arrive in Phuket from June until October. Pattaya is not a famous diving destination, but beginners and experienced divers will be rewarded with some of the best wreck diving in Thailand. So, clean up the lens, replace the batteries and make sure that you have a watertight seal, because when you dive in Pattaya the camera never lies. You really can see Turtles, Seahorses and Sharks, and the wreck dives will leave you breathless (pardon the pun) as you drift along US Landing Crafts from the Second World War that were intentionally sunk by the Thai Navy for the local Thai divers and tourists on a scuba diving holiday in Pattaya.

Mares Nemo Excel Dive Computer

Whether you are interested in technical diving or going pro some time in the future, you will need a dive log showing you have enough experience to move to the next level. Some resorts even insist on seeing dive logs before they will take you to some more advanced dive sites. In these days of increasing litigation it is good for them and for you to know that your fellow divers are experienced enough for the dive.
2. you can track how much you breathe and see it improve

We all want to spend as much time underwater as we can. Usually are limits are set by how fast we breathe our air. It is really nice to see how much we relax over time and our breathing slows to give us more time underwater.
3. its a journal of your diving adventures you can show and tell

You come back from your vacation buzzing with great stories of your dives. Pull out your dive log with your photos and you can answer all the ‘how deep/how long/how warm’ questions. When you get your buddy to sign your log book you can put names to faces on your group photos as well!
4. the quickest way to check the weights you need for different kit

If you dive throughout the year in different waters you will be snugged up on some and minimal on others. Why waste any time on your first day of your vacation testing for weight when you can look it up directly from last year?
5. its where you collect your shop chops

Some of them are funky, some plain. Shop chops (or stamps) are only available from the dive resort after a dive. How many do you have?
6. a great excuse to get that cute diving guide to share his/her email

No diver is going to refuse to sign your dive log and while you are standing there its easy to suggest you stay in contact. Need we say more?
7. your manta ray sighting is recorded for all time

You might want to frame it and put it on the wall (or record it on an online dive log for all to see) but you definitely want to record it for posterity!
8. helps you learn fish identification

Your dive log is the perfect place to keep notes and sketches of fish you could not identify underwater. It already contains information about the dive site and depth you were at, both of which help narrow down potential species. You never know when you will bump into a marine biologist and you can whip out your dive log and impress them with your drawing!

9. easy comparison of dive sites year on year

Do you have a favourite vacation destination? If you go back to the same dive sites often, just a few notes in your dive log will help you track changes in fish life and environmental changes.
10. its got all the stats of your favourite sport

How many? how deep? what countries? how often? Its all there with a dive log. With a paper log you have to add things up yourself but there are many software dive logs and online dive logs that will do it automatically for you. It’s not everyone’s bag, but well all love to compare and discuss so let some somewhere do it for you and you always have the information at hand.

Heard all the reasons for not keeping a dive log. Read the top 10 I have heard at top 10 reasons for not keeping a dive log
