Dive computers are undoubtedly one of the most important pieces of equipment for professional divers.
Getting the right dive computer can make or break your expedition, and so it is of utmost importance to make sure you pick the right one.
Below, you’ll find two of the best, at least in our opinion.
Our Pick of the Best Dive Computers
Below, you’ll find some of the dive computers that we think are worth investing in. All of these have unique qualities that are sure to add something to your dive.
Shearwater Perdix Dive Computer
The Shearwater Perdix Dive computer comes in two different variants – the regular Perdix, and AI, which is the integrated version. So these are designed for technical divers, and they give you full range of control over everything, from the color screen to your gradient factors. Everything on the inside you can really customize this – a very popular dive computer indeed.
We’re looking at the AI version – the AI only differs from the regular version in that it has air integration, which is an optional extra. This just means that you can buy a wireless air transmitter fitted to your regulator, and this would pick up information the other one won’t.
Dive Box Features
The box is compact and semi-rigid, but very protective. As a case, it is really compact compared to a lot of dive computer boxes, which can get big and cumbersome – this ins comparison is actually practical, and can be reused in order to keep you dive computer safe.
Inside of the top, you have a zippered section, which includes a quality checklist, which shows someone has physically gone through and made sure that everything is working on that dive computer, which is a particularly nice touch.
Also in the top, you there is a little section, which houses a tool for battery replacement, as the Perdix uses a changeable battery. The computer uses a single double-A battery, which as you know, can be found the world over.
This can be changed whenever needed; this makes it quick and easy just to swap that out. You’ve also got a couple of spare O-rings for the battery compartments, so if they wear out, or if you are ever unsure of them, you change it out and make sure it’s properly cleaned.
There is a carabiner that fits on the D-ring, and also a Bluetooth dongle so you can download your dive via Bluetooth. Both of these computers have Bluetooth built into them, so instead of carrying cables, you can just download your dive to your desktop computer wirelessly through Bluetooth.
You’ve also got some product information on small card, which supplies ample information, so reading through that will provide you with everything you need to know. You’ve got two options for straps on this dive computer – you have paired, elasticated webbing straps, which come with rather nice buckles that thread through the dive computer.
The elastic makes it great for dry suit diving and thicker wetsuit diving. It means it’s always going to hold onto your wrist, even if it starts to compress, but is nice and comfortable if you’re just wearing it over bare skin.
You also have some latex surgical tubing, which is very simple and can be mounted directly onto the computer. This is also elasticated and is rather quick and easy to slip on your wrist.
There is a pair of stickers, which are handy, and a quick start guide which details the air integration. This guide is very easy to read and navigate, and it shows the screens and what everything means.
Breaking down the computer itself, the computer has a user changeable battery and is slightly smaller than its older brother, the Petrol, and has a slightly smaller screen. The screen is just .2 of an inch smaller, put provides a much greater battery life, depending on the battery that you put inside of it.
Again, this is much more compact and streamlined compared to its bigger brother, but inside it does but most of the same thing. The battery compartment simply requires unscrewing by a few turns in order to change the double-A battery. It’s also nicely contoured, and fits around the wrist really easily.
On the underside, you have the threaded loops that you can put those elasticated straps through, and these are some little holes for the surgical tubing. Either side of the dive computer are electric buttons, which don’t require any kind of push or mechanical force. You can use them with gloves, and can cover them up with a silicone protective cover, while still being able to use the batteries.
The screen is full-color, and is very easy to read, with a color-coded display. If everything is white and blue, then everything is in order. If the screen turns orange and red, then there is something wrong that needs to be addressed. However; you can also color-code it to your preference.
Suunto Zoop Dive Computer
The Suunto Zoop Dive is an entry-level dive computer, and so is ideal for recreational diving, but would also make an ideal backup computer, especially if you need a second one. It is a very rugged design, being nice and strong, with a nice large LCD display on the front and a straightforward menu system.
Audio and Visual Alarms
The computer comes with audio and visual alarms as well. Our model was a wrist-mounted version; with a nice large watch style strap, ideal for fitting over the top of dry suits, but can also be tightened to fit over wetsuits.

This can be exited by pressing the quit/mode on the side, which sends you back through the main dive screen. Some of the modes included on the menus, accessed by pressing the mode button, will send you through to the second menu.
Memory and Set Menus
On the second menu, you have another two additional menus – a memory menu and a set menu. Going through to the menu memory menu first, and pressing the mode button again, the memory menu shows a logbook setting, a history setting and a PC set setting.

There is a dive time alarm at the start, which can be turned on and off by pressing the sections on there. You can then set your dive time; once reached, you will get an audio and visual alarm. Again, these are adjusted just by the buttons at the bottom, so you increase and decrease the required time.
There is also a max depth alarm – again, this can be turned on and off using the buttons, and adjust the maximum depth. After having set the alarms, you have the set time, so you cane set the time on the watch, so it’s showing the correct time. On top of these, we have some additional settings, where you can set your altitude adjustment, which is handy if you’re diving above sea level.

The Leonardo is an entry-level dive computer – so if you’re buying your first dive computer, this is definitely one to take a closer look at.
