Finding the best Scuba diving computers is not like the search for generic wrist-watches that you buy off the market with little or no knowledge about their technical features. Whether you will are buying your first or fourth diving computers, you can encounter a bit of a tough decision-making process. This indecisive encounter is largely underlined by the deep technical details that surround the judgment of purchasing one. There is the reliability issue, the ease-of-use, the technical capacity and many others.

The agitation usually felt in making this decision is usually well justified – if anyone was to decide on the purchase of a gadget that holds life-worthy decisions, they will be more careful too. To make things very easy for you, this article is set to review the very best of scuba diving computers available on the market. To further aid you in this search, we will first discuss some things that you should look out for in your preferred dive computer. Come along.


Best Options For Beginners / Pro Divers

There is no mincing word here, you cannot make purchasing decision of a dive computer based solely on the fact that you find it attractive and colorful or for any other casual reason at that. Frankly, making such choice should be hinged only on what is fitting for your diving need and that may not be the most fanciful dive gadget available.

If you are a new entrant or a beginner to scuba diving, the best recommendation is to go for a very simple and plain dive computer. Reason being that you will be better positioned to make the clearest decisions and get the important details you need more clearly.

You don’t want to be battling with how to maintain buoyancy, breathe properly and getting comfortable while still adding the mentally tasking feat of trying to decipher the information on your diving computer.

By any means, the advanced and professional divers can opt for computers with many side-features and technicalities. There is obviously no issue with this. For one, they know their way about scuba diving and underwater experiences already, so they only need to focus on the few necessary things and the dive computer’s monitor is one.

Simple Display or Complex Interface?

Don’t get this twisted, the underwater situation is a point where you are better off with the most simple and direct kit than having one that adds to your mental tasks – at least if you are a beginner. Most important here is the simplicity of the display so you can fetch information easily and quickly. This will aid you in making the most of your energy while diving.

However, if you are already well informed and experienced, you may not have much of an issue juggling this. Regardless, however, a dive computer that offers large displays and clear information is generally better than the one with a clumsy interface.


To be straight-to-the-point, some dive computers are more user-friendly than others. What this means is that they are more easily read and understood than others. I don’t think you will like to exert most of your energy trying to operate and manipulate your scuba diving computer.

Also important to user-friendliness is the ability to operate the computer without any hitch at all. By hitch, I mean to operate the buttons regardless of the water condition you are in.

Consider The Style

In scuba diving, there are two prevailing styles of computers: the wrist and console types.

In working, there is really no difference between the console and the wrist computer aside that one is worn on the wrist and the other is attached to some other dive gears – a compass or manometer.

Using the wrist type, you have more flexibility and freedom to maneuver while performing your scuba dives. The console, however, can have all of your gauges attached to one unit and accessible in an easier way. Which of the two that is best for you is dependent on your preference and choice.

Air Integration Feature

An air integrated computer has the ability to read the pressure in your scuba diving cylinder while giving you the needed report. Reporting it then take away the need for a pressure gauge.

Some dive computers give you more features by calculating the number of minutes of air remaining at the current depth and exertion level. It helps you to make the best scuba dive management decisions at any point in time.

Another of the good features of the Air Integration is that it can be synchronized with your PC or laptop creating an extensive report that shows the amount of air you were drawing from the cylinder at any time.
