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.
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
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.
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
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
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.
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.
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
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
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.
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.
This computer is compatible with transmitters from Oceanic and Scubapro, but existing transmitters must say FCC ID: MH8A on the body.
If so it will work with the Perdix AI.
