Shearwater Perdix 3 Dive Computer Combo
The Shearwater Perdix 3 Dive Computer is a robust full-size dive computer built for reliability. It boasts an ultra-bright 2.4-inch AMOLED display and is protected by an armoured casing, precision-engineered titanium bezel and reliable titanium piezo touch buttons. This enhanced electronics are safeguarded by its robust construction. The vivid full-colour display and extensive customisation options make the Perdix 3 adaptable to every diver’s needs.
A refined user interface simplifies menu navigation while the trusted vibration alert system ensures critical dive moments are never missed. Air integration with up to four Shearwater transmitters allows divers to grow from a first dive computer to a powerful tool.
BIG LAYOUT
The new Big layout lets users switch between standard and giant fonts for the easiest viewing experience on any Shearwater computer.
CUSTOMISE YOUR COLOURS
While your dive data shows critical safety information, display colour customisation offers one of the most flexible ways to personalise your computer and improve readability in real-world conditions. Choose from 15 colours for thousands of possible combinations.

The Swift connects to Shearwater dive computers to provide air integration capability.
Works with all current Shearwater air integrated dive computers are compatible with Swift GPS. This includes the Perdix AI, Perdix 2, Petrel 3, NERD 2, Teric, Tern TX, and Peregrine TX.
AI stands for Air Integration. This refers to a system that uses wireless transmitters to measure the gas pressure in a scuba tank and transmit this information to the dive computer for display and logging. Data is transmitted using low frequency (38kHz) radio communications. A receiver in the dive computer accepts this data and formats it for display. The communication is from the transmitter to the computer without requiring a response. Two (or more) dive computers may be programmed to receive the same transmitter(s).
Although the feature is named “Air” Integration, other gas mixtures can be used with the system as well. When using gas mixtures with oxygen content above 22%, be sure to have proper training on such mixtures, and follow proper cleaning and material compatibility guidelines. Swift transmitters are built with O2 compatible materials.
