Perdix ai

  • $935.00


The Shearwater Perdix ai is definitely an OTA favorite. The original Perdix is our best-selling computer and we have even higher expectations for the Perdix ai!

How did Shearwater make one of the world's most capable technical diving computers, which is also the number one choice for rebreather divers all over the world while still being the most user friendly recreational diving computer on the market, better? They made it air integrated!

This is the only computer that can take you from a newly certified open water diver all the way to a full on deep rebreather diver.

We like to say that the only reason that you will ever need to buy another dive computer is because you want TWO Perdixes!

Introduced in 2016, the Perdix ai from Shearwater Research of Canada 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 Perdix ai 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 Perdix ai offers an information screen utilizing a large full color 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 Perdix ai provides complete information displays of all required stop times. The Perdix ai 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 ai 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 ai 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 Perdix ai has been designed to accept any type of AA size battery including alkaline, lithium and rechargeables. Included with every Perdix ai from Outside The Asylum Diving & Travel are two elastic straps with buckles, elastic tubing for configuring using the 'bungee" style wrist mount, dual o-ring seal gold contact battery door and battery already installed (ready to dive out of the box!), two spare battery door o-rings, USB Bluetooth adapter, printed Quick Start Guide with instructions for downloading the full manual and desktop software from the Shearwater Research website. The Perdix ai also includes a screen protector already installed to help prevent scratches of the display face. The software includes a complete dive log manager, compatible with both MS Windows and MAC OS X. The dive log manager supports log downloads and firmware updates via the Bluetooth wireless interface of the Perdix ai.

Key features of the Recreational Open-Circuit mode (aka Recreational Nitrox mode) include a simpler menu structure, less cluttered display with a larger font and configurable bottom row, optional safety stops, and a no-decompression limit dive planner. The simplified settings allow for three breathing gas mixtures (Air or Nitrox) and places a greater emphasis on the maximum operating depth (MOD) and no decompression time limit (NDL). The display prominently warns the diver if their depth is near, at or exceeds the MOD of the selected breathing gas. The diver also simply selects one of three levels of NDL conservatism and during the dive a bar graph turns from green to red as the diver approaches the NDL. An optional 3 minute countdown safety stop starts when the diver reaches shallower than { 20 feet | 6 meters } on the ascent. If the diver exceeds the NDL and requires stops, the display turns red and warns "DECO STOP" with the mandatory depth and stop times.

 

Varying Permeability Model (VPM-B and VPM-B/GFS) decompression algorithm is also available.
