Shearwater Perdix 3 Dive Computer

The Perdix 3 is Shearwater's toughest and most reliable full-size dive computer yet. An armoured casing, precision-engineered titanium bezel, and titanium piezo touch buttons protect the enhanced electronics within, while an ultra-bright 2.4" / 6.1 cm full-colour AMOLED display keeps your focus where it matters most — on the dive.

A refined user interface makes menu navigation more intuitive than ever, and the trusted vibration alert system ensures critical dive moments are never missed. Air integration with up to four Shearwater transmitters gives you room to grow from your first dive computer to a powerful, advanced setup.
