Using Multiple Transmitters

 

The Swift is designed with the use of multiple transmitters.  The transmit interval of each 

transmitter varies within a 4.8 to 5.2 second time period and each Swift includes a receiver 

used to check for other transmitters and avoid colliding with their data.  Four or more 

transmitters may be used simultaneously, without the need to use multiple transmitter types 

(colors used on legacy Shearwater transmitters).  It is important to ensure the transmitter 

identification displayed on the dive computer matches the tank the transmitter is attached to.  

It may be useful to apply identifying paint or tape to transmitters if using multiple units. 

Legacy Shearwater transmitters may be used with the Swift in multiple transmitter 

configurations, although the maximum should be two (one grey, one yellow).  Best results will 

be obtained by using all Swift transmitters, as the legacy transmitters do not avoid collisions 

and will increase the amount of lost data. 

Using Swift with other brand dive computers 

Swift transmitters may be used with other brands of dive computers that are compatible with 

Shearwater transmitters.  However, this operation cannot be guaranteed.
