Shearwater Perdix AI Dive Computer

Shearwater Perdix AI comes standard with no transmitter. During checkout please select no transmitter or Add Transmitter for $350.

Shearwater is proud to introduce the newest member of the Shearwater family: The Perdix AI. Offering all of the same great features of the Perdix, the Perdix AI uses its large, easy-to-read screen to clearly display the tank pressure as well as your gas time remaining (GTR). The Perdix AI is capable of connecting to either one or two transmitters giving the diver the option to monitor both tanks or dive sidemount.

The Perdix AI dive computer from Shearwater search, is a robust dive computer for technical divers of all levels, and ready out of the box for air, nitrox, and trimix gasses. The Perdix AI is the newest offering from Shearwater, similar in design an operation to the Petrel line of dive computers, but in a smaller form factor.

Its simple 2-button interface and easy to navigate menu structure allows for intuitive and quick operation underwater. The Perdix AI features a large, high resolution LCD screen is both easy to read, and power efficient. The Perdix AI operates on any AA sized battery, and is user-replaceable in the field with minimal effort. The included digital compass is both accurate and smooth, and Bluetooth integration offers download and upload capability from Mac, PC, and iOS devices.

The Perdix AI may be used for open-circuit and closed circuit-diving, as well as gauge mode if desired

The small form factor of the Perdix AI does not allow for an external connection for rebreather oxygen cell monitoring. Despite this, closed-circuit rebreather divers find the Perdix AI more than adequate for CCR decompression calculations using a manually entered PO2 setpoint.

In closed-circuit mode, the Perdix AI stores banks of 5 closed-circuit diluent gasses, as well as 5 open-circuit bailout gasses. In open circuit mode, 5 bottom mixes, and 5 decompression gasses may be stored. Gas switching is performed quickly and easily with minimal button pushes. Gasses may be added or edited while underwater – useful for lost gas scenarios.

Decompression Algorithm

The Shearwater Perdix dive computer features the following modes of operation:

OC Rec - 3 gas nitrox recreational computer
OC Tec - Multi gas, trimix decompression computer
CC INT - Closed circuit fixed PPO2
Gauge - Bottom timer with stopwatch and dive logging

All Shearwater dive computers use Buhlmann ZHL-16C as the decompression algorithm. User adjustable conservatism may be achieved by manipulation of gradient factors settings in the computer’s settings. An optional VPM-B algorithm may be purchased if desired, and installed in the field.

The 2.2" Color LCD display is easy to read, with high contrast, and automatic screen brightness. The display may be customized with user-defined font colors, and may be inverted for those who wish to wear the Perdix AI on their opposite arm. Several layouts may be selected from, and fonts may be customized for size and color.

The user interface is simple to use with adaptive menus. Commands are entered with piezoelectric buttons. Warnings are clear and concise using color-coded fonts. A simple 2-button bailout allows for quick and easy changes to open-circuit. No confusing icons are used; rather the Perdix AI navigation is done with plain-language. Divers have a choice of metric, or imperial units.

The Perdix AI operates with any AA-sized battery. Shearwater Research recommends the use of Duracell Coppertop alkaline batteries for their widespread availability, and reliability. Shearwater dive computers will operate about 30 hours on a quality alkaline battery, or up to 95 hours using Saft LS14500 batteries. Li-Ion, NiMH, Photo Lithium 1.5 and Zinc-Carbon 1.5 batteries may also be used.

The Shearwater dive computers also features a super-capacitor to keep track of your tissue loading in the event a battery change is required between dives. This capacitor holds enough energy to maintain tissue status for 15 minutes. This means that if your battery change takes less than 15 minutes you can continue with repetitive dives, and don’t have to reset the date and time.

The Shearwater Perdix AI features a 1000-hour dive log, which may be downloaded via Bluetooth to a Mac, PC or iOS device using free Shearwater Desktop. The Bluetooth feature may also be used to upload firmware updates, when available.
