A Little Background

Diving is a sport and a hobby that is popular for most young and old people. Diving involves using breathing apparatus in order to get into the bottom of the ocean, sea, lake or any kind of body of water for you to see all of the animals, plants and other underwater life that you might want to see. In fact, some people also find relics and sunken treasures when they perform diving as an activity for vacation.

There are many benefits to diving under the sea or in any body of water. First of all, it makes your heart stronger and it also gets you physically fit. It is good for your cardiovascular system and it is also a great way to help you relax your  mind. Once you perform diving into the ocean, you will find life much more meaningful because of the beauty of the underwater world, which can be breathtaking sights.

Diving requires a lot of skill and willpower for you to execute it properly. Most experts give you training first before you actually perform this kind of activity, as being under the water for too long can make it hard for you to resurface back to get some fresh air. It is important that you stay cautious, listen to and look for hand signals and cues and cooperate with others who are diving as well for you to stay safe.

A dive computer is a kind of clock or device that measures how much time you need to stay under the water to avoid getting decompression sickness, which can be bad for your health. Decompression sickness means that you have run out of oxygen to breathe underwater, and you did not make it in time to give you enough oxygen. This is why it is crucial to have the right gear and the right timing for your diving and resurfacing.

One of the many features of this kind of clock is the fact that it may have an audible alarm so you can get alerted as to when to arrive to the surface. This kind of clock can signal like an alarm clock to help you get notify when it is time to go and how much time you have spent underwater. This can also be a great way for those who do diving to measure time as a record.

They can be worn on your wrist, much like a wristwatch, or you can also attach them to your pressure gauge or diving console. They can be very easy to operate and may work like you regular digital watch or smart watch. Inside each of these clocks, they can have some complicated circuitry, and this is why they are protected by a completely waterproof and watertight housing to protect the electronics inside.

Remember that this kind of device is only a guide and you should not always depend upon it when making your dive. Solely relying on this kind of device is not always good because there are situations that machines can become faulty. Therefore, if you think that your device might fail anytime soon, make your way to the surface faster than you think you should to avoid decompression sickness altogether.

How We Picked

If you want to have the best dive computer for your needs, here are some criteria to look into:

Screen clarity: you should pick one that has a very clear screen for you to easily read the numbers and the text with great clarity. It is also important that you pick one that has a good backlighting, because it can be very dark and gloomy under the sea or body of water. You should consider the screen to be easy to read and also easy to operate overall.

Form of attachment: some of these diving gears don’t really get worn on your wrist – some of them need to be attached onto your diving gear, such as a diving console. If it is worn on your wrist, it should be easily worn and it should not give you hassle. For those that are attached to the diving console, they should not be a problem to put together so they won’t fail you when you are diving.

Ease of wearing: as to reattaching it when you need to adjust it, the ease of wearing should be consider if your diving gear is one that is worn on your wrist. It should be comfortable and not too restrictive and should have adjustability much like a wristwatch or a smart watch. It should be made of skin friendly material as well as waterproof material along with the watch itself.

Security of the wristband: you may need to consider one that is very secure so that it will not fall over or get lost in the bottom of the sea or ocean, or even a lake when you perform your diving activity. The security of  your diving watch is important at all times.

Audible alarms: the alarms of this device should be audible enough for you to hear in the bottom of the ocean or body of water, since sound travels much slower under the water as compared to when you are on the surface or in air. Consider a very audible device to alert you when to resurface based on your dive time and the amount of air that you have left.

Number of features: consider the features that you would want from a regular diving watch, depending on your skill level. Some advanced diving personnel may also want to have other features that are for professional level diving.

Q: What are the basic features that can be found on this kind of diving gear?

A: This diving gear has the following important features for you to use:

Feature

Definition

NDL or No Decompression Limit

This is described as the amount of time you should spend in the bottom of the water before you need to go back to the surface. To be safe, you should save at least 5 minutes before it completely goes to zero, especially if your swimming skills aren’t that good.

Current depth

This tells you how much deeper you have gone through with your diving activity. Most watches are like GPS devices that get updated automatically.

Total time

The total time tells you how long you have gone through your diving activity. This is important in creating personal records for most people as well as for professionals.

Loading Bar or Graph

This tells you how much nitrogen you still have in your diving apparatus. This is also called the tissue loading bar because it measures your body tissues in accordance with nitrogen.

Battery warning

This alerts you as to when the device is low on battery, by which you need to ascend right away because you don’t know what will happen next without your trusted diving watch to be your companion.

Ascent rate

This is the rate of how faster you have ascended. This is important so that you don’t get decompression sickness. You should ascend slower than 30 feet per minute for safety.

Previous dive information

This displays all of the information you have logged into the watch from your last diving activities which can be helpful for you to compare and beat your personal best.

No stop time remaining

In most watches, the NDL or no decompression limit can be accompanied with a countdown timer for you to easily know how much longer you need to stay at the bottom or resurface back as much as possible.

Q: Aside from the important features, what optional features can be available with this kind of diving gear?

A: There are also many other optional features that you may be able to find on it, such as the following:

Feature

Definition

Altitude adjustment

This can be done manually or automatically depending on the model of diving watch that you have.

Multiple gas computers

This is use for those who want to do technical diving or use a CCR or closed circuit re-breather function

Air levels

There are some dive gear that can display the amount of air in your tank precisely, in which you can connect your gear to your regulator using a hose.

PC connectivity

Some can connect to laptops so you can save your diving logs and study or analyze them for later.

Electronic compass

For when you want to find your way or if you are lost under the sea and don’t know which is north, south, east or west while at the bottom.

Thermometer

Some models also have a built-in thermometer so you can measure the temperature while you are at the bottom of the ocean or body of water.

Dot matrix games

These unique menu games can make you less bored when passing the time by to wait for the right time you should go back to the surface.

Replaceable batteries

There are units that come with batteries that can be replaced other than being recharged.

Q: How is recreational diving different from professional diving?

A: There are some differences between the two:

Recreational diving is done for mostly enjoyment, hence “recreation”, and can be short in their diving times, from 30 to 45 minutes, and usually involves very simple tasks.

Professional diving takes diving to a different level, usually as part of a job, such as for search and rescue operations, hence their diving times are longer.

Q: What is decompression sickness and how do I do something about it?

A: Decompression sickness is a common phenomenon and sickness that most people experience from diving. It is characterized by the following symptoms, which can appear from 15 minutes to 1 day depending on the person, right after the diving session:

·         Getting unconscious or falling into fatigue

·         Dizziness or vertigo

·         Joint pains

·         Forgetfulness

·         Getting a numb sensation

·         Becoming confused or having a change of personality

·         Skin rashes or itchiness

Here are the main reasons as to why you probably had decompression sickness:

Resurfacing too quickly: the most common reason as to why you got this kind of sickness is because you probably went up the surface too quickly. You should maintain at least 30 feet per minute of ascent rate so you don’t get this kind of decompression problem.

Cold water: sometimes, being in cold water for too long can make decompression sickness more possible to happen.

Strenuous physical activity: too much exercise and strain on your muscles can also make this kind of sickness more likely to occur.

Too much time diving: if you have been diving too much then this can also happen, so it’s best to take rests for a while if possible.

To treat decompression sickness properly, you need to be in a decompression chamber, also known as a hyperbaric chamber. Even if it is only a mild case, it should not be treated simply by going back to the water, which can mean more trouble later on.

If you want to stay away from decompression sickness, here is what you need to do:

·         Make sure you are fit to do the diving by getting a medical check-up first.

·         Don’t perform the diving with shorter surface times in between.

·         Get plenty of rest if you want to go diving on a really large site.

·         Take some safety stops for at least 3 minutes or so.

·         Don’t do a seesaw dive pattern, because that can be strenuous for your physical capabilities.

·         Avoid removing your weight belt right away before you go to the surface.

Q: What is the air to nitrox option?

A: The air to nitrox option is a kind of diving setting that is usually found on most diving gear for you to set the nitrox settings. The usual amount of nitrox on a single dive is from 32 to 36 percent and different diving requirements may be switched between nitrox and air, which is usually based on the situation and the level of skill of the person diving.

Q: What common misconceptions are there with diving?

A: Many people make several stereotypes and misconceptions with diving, such as the following:

Misconception

Truth

Diving is a sport for the oldies or the seniors.

It is most certainly not, since it is mostly done by those who are physically fit, mostly those in the young adult to late adulthood stage. Scuba is a sport and hobby that can be dangerous if you are not fit for the job, and hence it might not always appeal to seniors and the oldies.

Diving is only suitable for tropical areas.

There are actually some diving sites that exist in not-so tropical areas, and some are even on colder areas of the world, usually featuring shipwrecks.

Diving makes you prone to getting eaten by the sharks.

Not all sharks are harmful, and they are usually fish that only hunt other fish, not necessarily humans, unless they are threatened. Just steer clear out of their way and they won’t really bother you.

In fact, statistics show that shark fatalities are significantly lower than dog attack fatalities. Additionally, more and more industries kill sharks because of their “industry” use, compared to actual shark fatalities. Yes, Hollywood is just making things more exaggerated.

You need a lot of cash to buy the gear / it’s an expensive hobby.

Of course it can cost you some bucks, but the basics of diving is only carrying a snorkel, a mask and a pair of fins. If you want to be a professional diver, that is only where it gets costly.

Diving is for the boys only.

Most certainly not – many girls have been diving a lot lately and they can even be instructors, just as there are female swimming instructors in your local swimming club.

You need to be a professional swimmer to go diving.

If you can swim up to 200 yards without stopping, no matter what your swimming skills are and your fitness level is, as long as you put your mind to it, you can definitely go diving, even when you’re not super fast in swimming.

Getting scuba certified is a hassle and expensive.

The price range is usually $250 to $500, with ones that are cheaper, and the certification can also give you some other freebies that you won’t get elsewhere. Scuba certification is most certainly cheaper than your indoor exercise gear and perhaps a movie-dinner date.

Diving can be bad for your ears.

This is half truth and half myth, because there are ways to equalize your ear pressure properly using the basic Valsalva maneuver that they teach in most scuba lessons.

Those with medical conditions can’t go diving.

This depends on the medical condition. You can get a second opinion if you really want to go diving so badly, and who knows, maybe there are certain exceptions to the rule.

Scuba diving and snorkeling are the same thing.

No they’re not (explained later below), as scuba diving involves going into the surface of the ocean floor, whereas snorkeling is basically just floating above with your basic snorkel gear.

Q: Are swimming lessons required for diving?

A: There is no direct answer for that, but basically you need some basic floating and swimming skills, but you don’t have to be a professional in order to go diving. The basic requirements for diving are as follows:

·         You need to swim nonstop at a distance of 200 meters using any kind of stroke that you are comfortable with. There are no time limits on this one.

·         You should be able to float on or make your way on water for at least 10 minutes.

Regardless, swimming is still an essential skill that you need for diving. This is because if your BCD or buoyancy control device decides to fail, you have no other option but to swim using your legs. Having a lot of endurance while swimming is important so that you can save your life or you can also save someone else’s life.

Q: Is there a difference between snorkeling and scuba diving?

A: There are many differences to know between scuba diving and snorkeling, such as the following:

Criteria

Snorkeling

Scuba Diving

How to do it

Snorkeling involves simply keeping your head and nose under the water with your snorkel tube, reaching the surface once in awhile to breathe properly.

Scuba diving involves going into the water itself for longer periods of time, using a diving mask to breathe properly.

Purpose

Snorkeling is mostly done on shallow waters, coral reefs and for observing bodies of water and aquatic life.

Scuba diving is more than just observing aquatic life – some use it for engineering, military use, offshore construction, welding underwater and many more professional purposes. Some also use it for shipwreck diving and exploration.

Duration

Snorkeling usually takes time under the water as compared to scuba diving.

With scuba diving, you can stay under the water for longer periods of time.

Required equipment

You only need a snorkeling mask that has an L or J shaped tube for breathing, some swimming fins and you are ready to go.

You need a pressurized gas tank for breathing, a diving regulator with a hose, a mouthpiece, some swimming fins and a proper diving suit for you to go diving properly.

Training

You don’t really need to be trained with snorkeling because you don’t have to go into the water for longer periods of time.

Scuba diving requires training because it can be crucial to dive underwater for longer periods of time and conserve your breathing apparatus.

Concerns

You may get sunburn on the surface, get dehydrated, get stung by poisonous marine life or not being spotted by other boats passing by.

Decompression sickness, lack of underwater visibility, toxicity of oxygen, narcosis with nitrogen and other breathing problems with compressed air can arise.

Q: What are diving tables?

A: A diving table is what people used to rely on when the diving equipment weren’t yet invented. It simply shows how much time you need to spend under the water without resurfacing. It shows vital information such as the following:

·         The depth of your diving activity, usually measured in feet.

·         The pressure group, which is usually given in A-Z, is used for the secondary table, since there will be 2 tables for most diving planners (right and left side).

·         Residual nitrogen time, which is usually the white area in the chart or table.

·         No decompression limits, which are usually marked in a black box.

·         Safety stop requirements, which are limits that are usually in grey to indicate that you may need to take a safety stop for such.

·         The start of the surface interval, which is expressed in time records.

Q: What are some of the best diving sites for me to check out?

A: If you are new to diving and don’t know where to begin, there are many awesome diving sites that you can check out in the world, such as the following:

Navy Pier – located in Western Australia, they mostly have really cool marine life such as friendly white tipped sharks, scorpion fish, large rays, stargazers, lion fish, octopuses, flatworms and the like. You can also find some eels while you  go diving there.

Shark and Yolanda Reef – this diving site is located in the Egyptian Red Sea, and is famous for having the wreck of the Yolanda, which contains a lot of fish species for you to look at (and maybe take pictures of). The Shark Reef is also a good place to look at, as well as the Anemone City.

The Yongala – located in Australia, it is a wreck diving site in which the Yongala, a ship that sunk during a cyclone, unfortunately cast tragedy in 1911, by which weather alerts were nonexistent yet. In the shipwreck, there are many things you can find, such as tiger sharks, turtles, sea snakes, fish clouds, octopuses, bull sharks, manta rays and many more.

Barracuda Point – located in Malaysia, just right near Sipadan Island, this diving site is good for the rarest tropical species of barracuda as well as the bumphead parrotfish, groupers, white tips, jacks, turtles and other aquatic life. They could have some strong currents but the diving activity will be worth it due to the coral walls.

Thistlegorm – located in the Egyptian Red Sea, it is also a shipwreck diving site in which sunk in 1941 (the Thistlegorm) and had lots of cargo such as trucks, carriages, motorbikes, rifles and various war supplies during the war times.

Blue Corner Wall – if you want a diving site that has a lot of jacks, snappers, eagle rays and the like, you can go to Palau, Micronesia to look for them. You can also find some mantis shrimps, morays, barracuda, sharks, Napoleon wrasse and many more.

Manta Ray Night Dive – there’s nothing like Hawaii (Kailua Kona) when you want to find a good diving site, since it is, after all, a popular tropical destination in the world. The manta rays in this awesome diving site is one of the most beautiful things you can find underwater, which are also surrounded by plankton and natural ocean lights.

Richelieu Rock – this one is located in Thailand and you can find the unique ghost pipefish, some jacks, seahorses, frogfish, batfish, harlequin shrimp and many other pelagic fish. If your goal is underwater photography then this is the diving site for you.

Great Blue Hole – if you want a breathtaking view from up above then this location from Belize is a good itinerary. It mostly contains sharks and some cool coral reef. You can also find some tuna as well as pelagic fish. There are some nearby caverns as well that contain stalagmites and stalactites for you to look around after you go diving.

President Coolidge – if you want to find another shipwreck site then this is the one to go to – a WW2 luxury ship that sunk in the war. It was the SS President Coolidge and you will find this as a great marine reserve for you to explore, located in northern Vanuatu.

Q: What diving etiquette should I keep in mind?

A: As someone who goes on a diving activity, you should consider having a good diving etiquette with the following guidelines:

It is impolite to scatter your diving gear all over the boat. You should only put your diving gear where it is supposed to be, such as in a designated area. By doing so, you also put yourself at a less risk of losing or misplacing your diving gear.

Make sure you don’t pick up corals and other animals, especially in reserved marine sanctuaries. Marine life should not be disturbed because they can potentially attack you if they are poisonous, and aquatic life such as small fishes can also lose their home.

You should know your diving jargon. For instance, flippers can also mean children, goggles can also mean swimmers and your air cylinder is not an oxygen tank – oxygen is used only by professional diving groups and not by newcomers.

Much like in swimming, kicking your fins and feet too much creates a lot of bubbles and makes visibility for the other swimmer pretty bad, and it also looks impolite. You can practice your buoyancy skills with a little training for this.

Q: What are some of the most basic hand signals I should learn when diving?

A: Because you cannot communicate properly underwater, you should learn the basic diving hand signals in order to communicate with your partner properly. Here are some of the most common hand signals you can use:

Hand Signal

Purpose

How to do it

End the dive by ascending to the surface.

Do a thumbs up with your hand.

This is often mistaken for the “OK” signal by newcomers to diving.

Descend

Start the dive by descending to the water.

Do a thumbs down with your hand.

Stop

Tell your partner to stop for a while for something.

Use your whole hand as if stopping a vehicle or saying “wait”.

Eel – make a moving mouth gesture with your hand.

Ray – flap your arms.

Crab – make two moving mouth gestures.

Shark – place your hand on your head horizontally.

Turtle – place one hand over the other and wiggle your thumbs.

Q: What dangerous aquatic life can be a threat to diving?

A: You should watch for the following, as they can be a threat to your diving activity:

·         Jellyfish – they can sometimes sting and cause death

·         Coral – some are poisonous and fatal

·         Sharks – only dangerous when you feed them

·         Damselfish – can be aggressive but not fatal

·         Sea urchins – they’re spiky!

·         Titan Triggerfish – they can injure anyone

Q: What could happen if I touch marine life?

A: If you go diving and touch fish and corals, many bad things can happen, such as getting poison or causing panic to the fish. You might also get surprised at some fish that can be dangerous when they are disturbed.

Q: What things can I do underwater?

A: If you go diving then there are many other activities you can do, such as:

·         Play games such as hockey

·         Do some underwater CrossFit training

·         Stand along coral restoration projects

·         Go treasure hunting

·         Take underwater photography

·         Join the animals

Q: Is it possible to take underwater photos?

A: Yes, with today’s technology, underwater photography while diving is a breeze. All you need is a waterproof camera that is rated for the right depth of your diving activity. Just make sure you don’t touch anything when you take photos.
