Shearwater Perdix AI Review: Key Features
This dive computer is packed full of all the features any scuba diver would ever need. In our opinion, the features below are the best selling points of this dive computer.
4 Dive Modes
The Shearwater Predix AI features four different dive modes, allowing the dive computer to be used in almost any dive scenario you can imagine.
- In Recreational Mode, it can be used for diving with standard air or Enriched Nitrox with up to 3 gas mixes for serious recreational divers.
- It also has an Open-Circuit Technical Mode that will make full decompression calculations for trimix diving.
- And, a Closed-Circuit more with a constant po2 for diving with rebreathers.
- It also has a Guage Mode that will take time, depth, act as a resettable stopwatch, and allow you to see tank pressure information, but will not make any decompression calculations.
Vibrant Color Display
The Shearwater Perdix features 2.2 inches full-color LCD display that is bright, crisp, and easy to read in any position. The brightness of the screen can also be set to automatically adjust to variable light conditions. It also features a large easy to read digits and color-coded alarms on the display allowing you to monitor safety information quickly.
User Customizable Display
Another excellent feature of the Perdix is that it only shows the essential diving information relevant for the dive mode you’re in. This ensures no redundant information is displayed, keeping the display neat and tidy. You also have the option to adjust certain rows of information to further customize it to your liking.
Optional Wireless Air Integration
There are two versions of this dive computer, the original Perdix and the Perdix AI, the ‘AI’ standing for Air Integrated. The ‘AI’ version of this dive computer allows you to monitor your current tank pressure as well as your Gas Time Remaining. It’s also capable of connecting to tow wireless transmitters, which is great for monitoring two tanks or when diving Sidemount. It also, capable of displaying tank pressure in all dive modes.
Slim, Low-Profile Design
One of the main feedback from customers about the Petrel is its size, and Shearwater Research listened. They designed the Perdix to be 30% smaller in volume than the Petrel. This makes the computer more streamline and lighter on your wrist.
Another feature that makes the Perdix stand out from others on the market, is its highly responsive digital compass that’s simple to read, use, and very accurate. It’s also 3 axes tilt-compensated, meaning you don’t need to have to the compass level to get an accurate reading. It can easily be accessed in all dive modes by pressing the right button once.
Bluetooth Smart Technology
You can easily upload your dive log to your PC, Mac, Phone, or smart device using Bluetooth Smart Technology via the Shearwater Cloud app. The App is fully customizable, easy to use, and full of useful information. It also provides a great way to download firmware updates for Shearwater. This ensures your dive computer keeps advancing as updates become available.
The Perdix AI is also equipped with a user-replaceable battery. It very simple to change and uses a standard AA battery that can be found worldwide. The battery plug can be unscrewed using a coin and has 2 o-ring for double security against floating the battery compartment. You can expect to get about 40 hours of battery like with air integration enabled. The transmitter also uses a not so common 3V Cr2 Lithium battery, so you might want to pack a few extras when on a dive holiday.

What We Like
The Shearwater Perdix is a very compelling dive computer and there are many things that we liked. However, these are the features that stand out the most to us.
The screen is easy to read and understand, even when packed full of dive information. The digits are large and can easily be read at a glance.
Although it’s a powerful dive computer with more advanced features like trimix and closed circuit. It is much easier to navigate, setup, and understand than many dive computers with more basic functions.
This is because of a simple dynamic two-button user interface with hints displayed on the screen that will show what each button does. On each menu screen, it will tell you what will happen if you push the right button and what will happen when push the left button. If you take your time and follow the on-screen instructions, you should get the hang of the computer very quickly.
We also liked the very responsive digital compass, it simply works. We like that there are not a lot of complicated features.
What We Don’t Like
We think the Shearwater Perdix AI is as solid as it gets. However, there are a few things we think need improvement.
The first is, there is no rechargeable battery. For the price, we were expecting this feature, like on the Suunto Eon Steel and the Scubapro G2. However, we cannot hold much grievance since it uses a AA battery that can easily be found worldwide and easy to change.
It can also only connect two wireless transmitters. This is great for side-mount diving but significantly less than a computer in the same price range that can connect up to 9 transmitters.
Despite these shortcomings, we still believe that Perdix is still one of the best dive computers you will find.
Who Should Buy the Perdix Dive Computer?
The Shearwater Perdix is designed for the more serious recreational or technical divers. A wide range of dive modes and capability makes it a great choice for divers who are looking for a dive computer to accompany them through their diving career.
However, this might be too much dive computer if you’rere looking to do more simple recreational diving. If you are looking for a dive computer with the same intuitive layout as that of the Perdix but with more simplified recreational dive modes, you should check out the new Shearwater Peregrine.
