Shearwater Perdix Dive Computer


Manufacturers Description


The Shearwater Perdix Dive Computer is a colour screen technical dive computer with a user changeable battery and customisable screen.  Smaller and more streamlined than the tried and trusted Petrel the Perdix has most of the same features but for a few small differences.

The Perdix is made for both open circuit and closed circuit technical divers who need a simple and powerful dive computer that can be adjusted and customised for them and their dive at hand when things change.

Piezo-electric Buttons on either side don't require any kind of movement or pressure to use them so are quick and easy even when wearing thick gloves.  The Centre Row Information on the dive screen can be customised and changed to what you need to know for your dive.
