The Shearwater Perdix AI is capable of wirelessly connecting to either one or two optional transmitters giving the diver ability to monitor up to two tank pressures and allowing for sidemount diving. It's also capable of calculating the Gas Time Remaining (GTR) on one assigned tank. Air integration is optional for all modes, from OC Rec to CC/BO. The tank pressure(s), in PSI or BAR, and GTR can be displayed to the customisable slots on the main display screen or accessed through the underlying information screens. Enabling the AI feature causes approximately 10% decrease in Perdix battery life.
Will my existing transmitter work with the Shearwater AI computer? Shearwater Research tells us that as long as the transmitter is marked with "FCC ID MH8A" on the body then the transmitter, regardless of the brand, will also work with their Perdix AI and NERD 2 model air integrated dive computers. However, no other Shearwater dive computer model, including the Perdix model without the "AI" designation and the original NERD, support integration with a pressure transmitter. The first stage regulator tank-pressure wireless transmitter supplied by Shearwater Research is actually manufactured by Pelagic Pressure Systems. Pelagic has been supplying those same OEM transmitters to various dive computer manufacturers such as Aeris, Aqualung, Hollis, and Oceanic for many years. 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 Shearwater Perdix AI 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.
After the dive, the Perdix AI communicates via next generation Bluetooth Smart Ready™ 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 AI has been designed to accept any type of AA size battery including alkaline, lithium and rechargeable.
