PRODUCT NOW SUPERCEDED TO PERDIX 2 TI SHEARWATER PERDIX 2 TI
The Shearwater Research Perdix is a full decompression dive computer incorporating the Bühlmann ZHL-16C decompression algorithm, with user configurable Gradient Factors (GF). Gradient Factors allow the diver unique and individual control of their dive computer decompression calculations. An optional PIN upgrade to the Varying Permeability Model (VPM-B and VPM-B/GFS) decompression algorithm is also available.

Out of the box, the Shearwater Perdix includes open-circuit and closed-circuit Air, Nitrox and Trimix mixed gas functionality. The standard firmware supports English language menus and both imperial/metric units of measure. New with recent firmware updates are several enhanced navigation features for the three-axis tilt-compensated digital compass.
The Shearwater Perdix model without the AI designation shown on this page has a lower price than the Perdix AI model. The Perdix AI model with the AI designation has the radio frequency receiver built in to the electronics and this is the reason for the difference in price. The Shearwater Perdix model shown on this page cannot be later upgraded to support tank pressure transmitters.
The Shearwater Perdix offers an information screen utilising a large full colour LED LCD display. The display will automatically adjust intensity based on available light to make the display easily readable whether on the surface in sunlight, in open water or in a cave.
During a decompression dive, the Shearwater Perdix provides complete information displays of all required stop times. The Perdix can provide time-to-surface based on "look ahead" at planned gas switches. Multiple gas definition presets are supported with any combination of oxygen, nitrogen and helium. The Perdix will NOT "lockout" after a missed stop or ascent rate violation. The included CCR mode for rebreathers provides the ability to perform constant PO2 set point calculations for deco.
After the dive, the Perdix communicates via next generation Bluetooth Smart™ with iOS devices such as the iPad and iPhone. In addition to current Shearwater and third party support for Mac and PC desktop applications, users are able to download dives using their iOS devices in conjunction with third party applications.
The Shearwater Perdix has been designed to accept any type of AA size battery including alkaline, lithium and rechargeables.
In the Box
Included with every Shearwater Perdix are two elastic straps with buckles, elastic tubing for configuring using the 'bungee' style wrist mount, zippered hard case, screen protector (already installed), dual O-ring seal gold contact battery door, and battery already installed (ready to dive out of of the case), two spare battery door O-rings, USB Bluetooth adaptor, printed Quick Start Guide with instructions for downloading the full manual and desktop software from the Shearwater Research website.
The Perdix was originally shipped in a cardboard box, but Shearwater now supplies the Perdix with a zippered travel case. The Shearwater travel case included with the Perdix is a very snug fit, suitable for dry storage, but not suitable for boat use or damp storage.

Warning
The Perdix as supplied by Shearwater, in addition to including their two depth compensating wrist straps with slide release buckles, also includes a length of latex rubber tubing for use with the bungee mount option. The Scuba Doctor does not recommend the use of the latex rubber tubing because of our concerns about durability, but if you do elect to use it then we suggest annual replacement of the rubber tubing and that you carefully follow the instructions in the full Perdix manual for how to tie the tubing. Use only the special secure knot described in the manual, and use two separate independent segments to make the two wrist loops.
If you wish to take advantage of the bungee wrist mount on your Perdix, you should consider using our abrasion-resistant braided nylon jacket shock/bungee cord in place of the rubber tubing.
