The Perdix 3 features a 2.2-inch AMOLED colour display protected by aluminosilicate glass. The housing is depth-rated to 260 metres and uses a user-replaceable AA battery, allowing divers to choose between alkaline, lithium or rechargeable NiMH cells.
The computer supports Air, Nitrox, Trimix, Closed Circuit/BO and Gauge modes, and can monitor up to four transmitters simultaneously. It includes an integrated digital compass and uses Shearwater’s Bühlmann ZHL-16C decompression model with Gradient Factors.
