What Does A Dive Computer Do?

While it is possible to use a dive watch while diving, a dive computer makes it so much simpler. According to PADI, a dive computer takes time and depth information during your dive and applies it to a decompression model.

The computer tells you exactly how long each safety stop must be during ascension. Using a dive computer is the safest way to calculate safety stops. More information is available at PADI's website.

Why Do You Need A Dive Computer?

A dive computer takes the guess work out of returning to the surface safely. Skin diver.com states the benefits of using a dive computer include tracking status of decompression state, accurate depth recordings, correct time recordings and indicators that record ascent.

Simply put, using a dive computer reduces mistakes that can be life-threatening. It can also give you more time underwater because it considers the depth of water as a factor.

Purchasing a dive computer is an important decision, so you need all the facts before buying. That is why we created this list.

Once you make a decision, you can look forward to more enjoyable and longer dives since the calculations are done for you. When looking at dive computers, it is important to consider many factors other than price. High quality equipment can be life-saving for scuba divers.

The best dive computer makes the whole process of scuba diving a lot more effortless. You can concentrate on the most important part of every dive: The underwater world.

The dive computer also is your personal logbook. It saves your past dives and makes it easy to transfer all the relevant data to your desktop device or share it with your friends.

How to choose the best dive computer?

Choosing the right dive computer for your needs is mainly about asking yourself what kind of diver you are. Here are some important points that you should take into consideration when you make your choice.

1. Consider your future diving career

It is important to have a clear vision of your future diving path before you invest any money. Just imagine buying an expensive gear and use it only once or twice a year isn’t that wasteful?

So think through your diving career and know your diving rate and your future goal.

As the Dive computer wizard suggest (Dive Computer Expert Reviews), decide whether you are a long time diver with many diving rates, and hence you require a durable computer with many features such as air-integration, digital compass, wireless air, and capabilities.

Or you are a recreational diver who just needs a computer with simple features.

2. Access and know your personal preferable mounting option

Today there are mounting options including computer consoles, wrist units, units embedded in a scuba mask, and dive watch computers to choose.

Therefore, you have to decide clearly what the best option for your diving style is. For quick decision you may consider convenience, the activities you will be doing for instance if you are an underwater photographer, you may select Aeris CompuMask HUD or the Oceanic DataMask HUD (Dive Computer Expert Reviews).

Again you can imagine how you feel when you wear certain model. However, this is a personal choice you have to make.

But you may go to dive shopping and try out different models to feel how easy using the model will be when you wear it.

3. Know your desired specifications and functions of a dive computer

Know which features will best suit you in a dive computer. Modern dive computers come with features such as PC interface, color display, wireless air-integration, digital compass, Dual algorithm, drive mode options, dive simulator among other features.

According to Sarah (Choosing the right dive computer for you), you should know your preferred feature that will improve your diving career.

You need to look for a dive gear that will exactly perform according to your desires.

More important you may want a gear with adjustable settings of Personal Conservative Factor, Deep Sea safe stop mode, Altitude, and user replaceable batteries.

But keep in mind that a dive gear with additional features may cost you extra money. Therefore just go for features that are useful.

4. What is your personal preference?

What preferences and personalized settings are you looking for in a dive computer? Your choice should be one that has your preference settings needs. According to Roger Roy (How

To Choose Your Next Dive Computer), the preference setting modes can include meter setting, feet setting, adjustable safety factors, audio and visual alarms, deep sea stops, and depth warnings.

Choose a dive that comes with the right type of settings according to your diving level, style, and your dive skills.

5. What is the standard of simplicity of use of the computer?

Before buying a dive computer, ask yourself, do I know how to use the gear? Or will I need to read the manual before I start using the dive computer?

These questions are important since they help you buy that equipment which is not a challenge to use. Besides, some computers are intuitive that will get you tempted to dive them without reading their manual, yet others need you to spend the time to master how to operate them (ROGER ROY).

Therefore, it is imperative you understand the model you want to buy.

Try to avoid getting one dive computer that you will not be able to operate at worst, or that will take a long time to master its operation at best.

6. What are your eyesight capabilities?

How easy do you see things? If you have sight problems, buy dive computer that has screen displays with an improved readability of the computer.

Many divers find bigger dive gears to be better. Besides, you can choose a gear that has bright displays to help highlight information to you.

7. What is your budget?

Budget is a more important aspect that you must give enough consideration. By saying this, I imagine that you do not want to reduce your family expenditure because you are buying the dive computer.

Therefore, you need to choose your equipment wisely and economically. After considering the above factors, you should make a selection of two to three computers that meet those factors and your need.At this point, you will have dive computer with probably same feature but with different prices.

As we have discussed earlier, models with the sophisticated feature are more expensive than those with few and simple model. So chose your option the dive computer which suits your pocket.

If you are working on a tight budget, you may get a simple model dive computer without some features such as wireless air integration, free dive mode, inbuilt digital compass.

However, if you have enough funds, you want to get yourself a sophisticated dive computer that will accelerate your diving career. In such case, you can select expensive dive computer.

These dive computers come with more capabilities such as wireless air-integration, multi-gas, heart rate monitoring, picture upload, and digital camera.

The last bonus factor is the color, but on this, you are alone. Choose the color that suits you.

The best way to understand the dive computer is to watch the below YouTube video by Dive computer wizard to help you make an informed choice: 

The video will explain to you step by step selection of best dive computer and will cover many other aspects that are not discussed in the article. So take your time and watch it!

You should focus on dive computers that match your dive style and the equipment you already have.

Do you want to read the display as easy as possible? Pick a computer with a primary screen that shows less info but big numbers.

Do you love graphics? Pick a more professional device that has a colored display to suit your needs.

However, the standard features that the best dive computer for your needs should have are measuring depth, timekeeping, display of ascent rate, emergency decompression, dive log and previous dive info.

It should also warn you when your battery level is low and work with nitrox enriched air.

You should also pay close attention to the menu structure. Some like to operate with a single button and others prefer 2 or 3 of them.

Either way, you will definitely find out what is best for you by reading the infos below.

A few more things you need to know for the time AFTER you made your decision:

  • Always read the instruction booklet. A dive computer can be a complex device.
  • Rinse your computer with fresh water everytime you used it. That is important for all your dive gear by the way, saltwater can be very aggressive.
  • Take good care of it while travelling.
  • Keep it cool and out of the sun when you don't need it.
