Tips on Choosing a Dive Computer

Since their introduction, dive computers have really revolutionized the way we dive. Before, divers would calculate their dive time based upon the maximum depth they dived to. Dived computers significantly changed this because of their ability to calculate a diver’s maximum dive time based on actual dive, something that allowed multilevel diving. Today’s crop of dive computers even constantly updates you on the amount of time you have left.

Modern day dive computers have superseded dive watches as they are packed with so many features and configurations that it can be a problem choosing exactly which one is the best one for you. In this article, we tell you how to go about choosing the best scuba diving computer for your needs.

Which mount style do your prefer

Do you want it clipped to your BC or strapped on your wrist? These days, this is more than just a question of personal preference. Latest dive computers provide comparable capabilities, irrespective of whether you go for wrist-mount, wristwatch, or console style.

How often do you SCUBA dive?

Do you scuba-dive only occasionally or do you do it regularly? In case you are just an occasional diver, it is advisable to invest in an easy compact wrist computer for instance the Suunto Zoop Novo. Such a computer is great for your current pressure gauge.

On the other hand, if you are a frequent diver, you will be better off with something more intricate, for instance Suunto D4i series wrist computer. Such computers are not only air integrated and easy to use but also feature a Freedrive mode. Thanks to the air-integrated design, scuba divers have the option of getting rid of the gauge console to free up important luggage space.

Back Lighting

The latest scuba diving computers feature backlighting, which enables you to see the screen display of your computer without having to use a flashlight. This convenience feature is one that many enthusiastic divers will really appreciate.


Most diver computers feature a dive log function that enables a diver to review their completed dives. These computers tend to have different numbers of dive logged. Before you decide on a computer, it is important to ensure that it can record enough number of dives at a given time.

The older scuba diving computers are only able to show the latest dive. Today however, the newest models can retain data for more than 10 dives.

Screen display

Although the latest screen displays have greatly improved computer readability, some divers still believe that bigger is better. In addition, new multicolored displays also help highlight information. So if your eyes are not very good, you will want a computer with greatly improved readability.

Depth Gauge

Not only can dive computers replace your depth gauge but they can also supplement it. In addition, they can record your different depths more accurately. Chances are that you will guess at some depths encountered in the course of the dive, unless of course if you use every second of your dive checking at your depth gauge.

Scuba diving computers carefully tell the amount of time you spent on each dive, and at the same time allow you to savor the surrounding scenery.


Choosing a dive computer is not easy given the fact that the latest ones have many features. It helps to know what you want, based on your diving experience, and needs.
