It's never been possible to record heart rate accurately during swimming - it is now!
The swim stores up to 20 hours of heart rate data during swims, then forwards it to a compatible device at the end of the session
Super wide and super sticky, this swim specific HR strap is designed to stay in place even during those fast training sets smashed out in the pool
Real-time heart rate is sent to the watch when the monitor is out of the water
A simple bi-fold adjustment reduces elastic weight and makes sizing easy
Additionally, the new straps provide advanced run metrics - by measuring cadence, vertical oscillation and ground contact time when paired with a compatible device
Battery lasts up to 18 months (assuming three hours/week use) with user-replaceable CR2032 battery
Bundle version available includes one of each strap
