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.

Your octo should always be secure, visible, and easy to access. Pair this with a clip or holder so it stays exactly where you expect it.

The SEAC bootie is ideal for people who are scuba diving or snorkeling with an open heel fin with adjustable straps. This bootie is fantastic to avoid chafing and other discomforts. Great for boat, pool and water sports. Not recommended for california shore diving as you want to look for a boot with a thicker, heavy duty sole to protect you from walking on rocks, hot sand, etc..
