The Swift transmitter by Shearwater.

The Swift replaces both the old grey and yellow transmitters. 

Users can now use 4 Swift transmitters together with no risk of cross interference -dur to the advanced collision avoidance system. This has been very popular with Sidemount divers, especially if they are carrying deco gas.  

There was a firmware update recently that now allows AI users to load up top 4 transmitters at once and also rename these cylinders (ie O2).

Uo to 300 dive hours.

Compatible with Shearwater Teric and Perdix AI as well as other computers on the market.  

Randomized transmit interval allows for reliable simultaneous use of multiple SWIFT transmitters
