Buying Guide


Allowing divers to monitor their time and safety while in the water, the best rated scuba diving computer is an indispensable device that both novice and seasoned divers should have. When used with diving tables, the most reliable scuba diving computer will allow you to stay longer in the water and to undergo shorter safety stops.



If you go for console-mounted types among the top ten scuba diving computers on the market, take note that such units connect with the rest of your diving gear through a hose. With such a configuration, console mounted models will not be easily misplaced or lost. This type of device requires battery power to run. It is not an air integrated unit, however. This means your console’s pressure gauge will need to be connected to your tank in order to display a pressure reading but the diving computer is not linked to the air source. Models that are wrist- or forearm-mounted can be used for free-diving as well. No matter what type you choose, the device should be able to calculate your max dive time based on the actual dive. This will enable you to carry out multilevel diving. Basing its calculations on your current depth, the device should be able to update you constantly on how much time you have left.


Navigation and Display

The highest rated scuba diving computer has a screen design that makes reading underwater, where visibility and lighting is poor, easier. The positioning and size of the critical data digits should be at optimal level at all times. A simple menu layout is preferred as the diver has to devote time underwater to maintaining buoyancy, swimming and fighting against undercurrents. A set of intuitive buttons can help immensely, so you can effectively use the diving computer without having to learn the content of the owner’s manual by heart. Dark underwater conditions should not deter you from viewing the interface, which should be easy to read.  The device should have programmable alarms and include low-battery alert capability.


Air compatibility

A scuba diving computer with air integration capability lets you calculate your respiration rate. It tells you how much safe dive time you still have left based on your current consumption of air. Using a scuba diving computer under water should enable you to get both desaturation data and pounds-per-square-inch data. A hose-free model employs a transmitter interlinked with a first-stage HP port. An air integration feature allows the device to monitor and learn the diver’s respiration rates. This helps the computer provide accurate calculations especially when you absorb less nitrogen, which can occur in instances where your breathing slows because the current is behind you. This facility lets you stay in the dive longer.


What is the best scuba diving computer? It’s the type that displays accurate readings and will not fail under extreme conditions in the water. Although you should still stick to your diving table, having a diving computer can encourage you to follow safety guidelines for a great diving experience and responsible diving.
