Shearwater Swift Transmitter



The Swift allows divers to carry multiple transmitters reliably. The collision avoidance protocol allows for multiple transmitters to be used at the same time with a lower likelihood of dropped communications. The Shearwater Swift transmitter is designed and built in Canada for demanding divers of all proficiency levels.

The Swift connects to Shearwater dive computers to provide air integration capability.

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 shearwater swift 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.
