Shearwater Perdix 3 Silver + Swift GPS Transmitter
The rugged Shearwater Perdix 3 silver dive computer delivers ultimate reliability for your underwater adventures. While retaining the form factor and dimensions of its predecessor, the 2.2" screen Perdix 2, it's upped the game, featuring a stunning, ultra-bright 2.4" AMOLED display with a higher 450×600 resolution that ensures exceptional clarity in all diving (and surface) environments.
Air integration with up to four Shearwater Swift GPS transmitters allows room to grow from a first computer to a powerful, proven, advanced technical diving solution.
Furthermore, a precision-engineered titanium bezel and an armoured casing protect the advanced electronics inside. Consequently, this heavy-duty design safely shields the dive computer during intense recreational diving and advanced technical exploration. Finally, extensive colour customisation options allow you to tailor the vivid screen for maximum readability.
In addition to its tough exterior, a refined user interface makes menu navigation faster and more intuitive. Divers can easily track critical moments thanks to the trusted vibration alert system, which clearly signals important notifications.

Shearwater Swift GPS Transmitter
Shearwater Research's Swift GPS Transmitter is engineered to provide divers with both reliable, real-time air integration and crucial surface location data, together with dive log maps. It represents a groundbreaking evolution of the trusted Swift AI technology into a single, compact, powerful unit.
While you'll enjoy all the features of the trusted Swift, receiving real-time gas pressure data and benefiting from accurate gas time remaining calculations for extended dive time, you'll also be getting a location accuracy of 4 metres based on a satellite reporting interval of 4.8 - 5.2 seconds.
Better still, if you already have a transmitter — or multiple transmitters —only one of them needs to be the GPS version to reap the benefits.
