With the understanding you now have about the importance of dive computers and their different types, there are some questions you need to answer before choosing the dive computer that’d best suit your needs.

The display of a dive computer is the first thing that strikes one about it. That’s why the size of the display is of such importance. Some have a dot matrix display which use dots and lines for the letters and figures displayed while others have OLED display where the letters displayed are lighted in themselves. The third type of display is the LCD, which is full color and emits light that makes the letters and figures visible. If you’re buying a dot matrix, look out for backlight features because you may be using them in depths where visibility is really low. Ensure that navigation is quite easy if you have to move from screen to screen to get your information. The display size also comes into play if you’re diving in deeper waters with reduced visibility or in a situation where your eyesight is poor. If this is the case, it’s advisable to purchase a dive computer with a display size that’s suitable for you. Also, consider the readings on display: how many lines are there and are they what you need?

Where would you prefer to mount your dive computer, on your wrist or attached to the console? These days, people prefer the wrist-mount to the console-mount because it’s easier to check your wrist than bend over to check your gauges all the time. There are other computers that are mounted on your dive mask which makes it a lot easier; you just look up and get all the information you need.

Dive computer manufacturers now make user-changeable batteries alongside the computers. If you have to return your computer to the store every time you need to change your batteries, it’ll mean staying without your computer for days or weeks, and that means no diving for you. If you’re to purchase your dive computer, ensure you go for one with replaceable batteries that you can change, even if you are in a dive (ensure your computer can store information so that you don’t lose your dive details once the battery dies). Also, take note of the run time of your battery so that you’re always prepared for a battery change.

Check that other features like alarms are inbuilt in your dive computer. The alarms help to remind you when you’re staying too long underwater and have forgotten to check your computer. An alarm could be a life saver. Dive computers with a warranty have an added advantage and, if you find one that meets your expectations and has a warranty, don’t hesitate to go for it.

Almost every dive computer can log in details of your previous dives. The issue is in the number of recent dives it can log. While some can log up to 10 – 15 dives, others can log up to 50 dives. So, depending on your frequency of diving and how often you want to review them, choose a computer that suits your logging need. However, even if you purchase one with less memory, if it’s PC-compatible and allows for data transfer, you can store up your diving logs on your computer and review them whenever you deem fit.

What gas would you be diving with? Ensure that you purchase a dive computer that’s compatible with your diving gas. If you’re Nitrox certified or you’re likely to use Nitrox in the future, purchase a computer that’s Nitrox compatible as you’ll be saving some money when you eventually need to buy one. For a slightly greater expenditure, you can get a computer that’s compatible with Nitrox, air, and Trimix. This saves you a lot of hassle. Be aware that some computers allow you to switch between gases while in a dive.

Underwater, you’re almost “driving blind.” The visibility isn’t as it is on land, so you need a compass to point you in the right direction. Traditionally, divers attached an analog compass to their consoles or wore it on their wrists, but these days, digital compasses are being integrated into dive computers. Ensure that your computer has a compass that’s accurate. Some other computers are integrated with GPS that can keep a record of where you’ve been and where you are with the use of satellites.

Most divers complain about forgetting to turn on their computers until they’re deep in water. Because of this, most manufacturers now add a feature to the computer that turns it on once in the water, and it shuts off outside water. If you think you may forget to turn your computer on, it’s advisable to purchase one that has this feature. Also, ask questions concerning the accuracy of the decompression calculations of your computer. However, for your safety, we advise that you should give a 5-minute leeway for any time provided by your computer. The dive computer is not infallible, after all!
