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.

Bluetooth Feature

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.

Webbing Straps

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.

Surgical Tubing

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.

Battery

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.

Electronic Buttons

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.

Full-Color Screen

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.
