Powerful. Simple. Reliable.

The PERDIX 2 is Shearwater's toughest and most reliable full-size computer yet. The armored casing with precision titanium surround bezel and dependable titanium piezo touch buttons protect performance-enhanced electronics.

An aluminosilicate glass lens guards a fantastic 2.2” bright screen and offers improved clarity, impact, and damage resistance. A strong vibration customizable alert system draws attention at critical moments of the dive.

Air integration with up to four Shearwater transmitters allows room to grow from a first computer to a powerful, proven advanced technical diving solution. This is delivered using the trusted and easy to find user-changeable single AA battery and familiar ergonomic compact form factor.

PERDIX 2 is available in Ti silver and Ti Black color finishes.

Merging state of the art manufacturing techniques, innovative engineered materials, and consumer feedback, Shearwater has successfully developed a low-profile, sleekly contoured design without sacrificing features vital to technical divers. It’s everything you love about the Petrel dive computer, just smaller.
