Introduced in 2016, the Perdix from Shearwater Research is a full decompression dive computer incorporating the Bühlmann ZHL-16C 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 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. The Perdix 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 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 setpoint 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.
