Introduced in 2016, the Perdix from Shearwater Research 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 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 the latest firmware update (V33) are several enhanced navigation features for the three-axis tilt-compensated digital compass.
