I would recommend this product to professional swimmers and their coaches who are enthusiastic and eager to improve results at a faster rate. Thanks for a wonderful invention, SONR!
Kat Berry
Triathlon coach
We found it was really helpful from a coach’s point of view for giving the swimmers feedback in real-time as they were moving along. The sound quality was really clear. I would definitely look to have SONR as a permanent feature that we could use on our camps.
Christine Haslem

This device is fantastic for pool training because the swimmers can hear with absolute clarity while they are swimming.
