HRM-Tri heart rate transmitter – for 920XT and fenix 3


  • 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
  • It also sends real-time heart rate to the watch when the monitor is out of the water
  • HRM-Tri strap is the smallest and lightest heart rate monitor from Garmin
  • Designed with rounded edges and no exposed seams, the strap remains comfortable during extended hours of training, and is designed to be worn under a tri suit
  • 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
  • Lasts up to 18 months (assuming three hours/week use) with user-replaceable CR2032 battery
  • HRM-Swim has the same features as HRM-Tri with a special non slip design – keeping the monitor in place – even during push-offs from pool walls
  • Bundle version includes one of each strap
