SONR Radio Transmitter

Coach swimmers in real time without shouting across the pool.

The SONR Radio Transmitter allows coaches to communicate with swimmers clearly during training, including while they are in the water. Designed for swim coaching environments, it connects to SONR receivers so swimmers can hear instructions, corrections, and cues when they need them most.

With communication support from up to 50m away and 1m underwater, SONR helps make coaching more efficient, especially during technical swim sessions, squad training, and group programmes.
