No Need To Shout Anymore, The Swimmers Hear You Anyway
SONR is a wearable radio receiver for swimmers, which allows the coach to improve their technique, during the training even when the swimmer's head is underwater. Shaped as a disc, it is located under the swimming cap to hear the voice of the coach.
Thanks to its sleek and lightweight design SONR does not provoke any discomfort. After just a few minutes of wearing, swimmers forget about the receiver's presence and fully focus on the training, with the coach available to guide them.

How to wear it?
-
SONR can be placed anywhere on the swimmer's head under the cap.
- If you are not wearing a cap, SONR can be fixed on your goggles strap.

Real-time coaching
Bone conduction technology allows the swimmer to hear the coach's voice being underwater. The coach can correct the swimmer's movements right when he needs.

Connect to an unlimited number of SONRs with a single radio.
Manage whole teams in real time, on 6 different channels. Switch channels on the radio, and talk to all swimmers at the same time, or specifically with one of them, or divide them into groups.
Up to 8 coaches can use SONR system simultaneously at the same pool.
