Suunto Smart Heart Rate Belt 2 - M/L
Description
Precision for Serious Training. Accurate heart rate and R-R data for athletes who train by intensity.
Trust Every Beat
An ECG front end identifies and rejects the artifacts that distort a heart rate reading, so the trace follows your effort through intervals, surges and long steady work. A new chest-strap construction shields the signal from static noise, holding readings stable from the first minute. High-resolution beat-to-beat R-R data is also what makes real-time ZoneSense possible on a compatible Suunto watch.
Wear It and Forget It
A 13 g transmitter, 36.5 × 36.5 × 8.5 mm, sits low and flat against the chest. The soft strap and silicone grip hold their position through surges and descents, so the belt stays where you set it and your attention stays on the session. Around 460 hours of battery life from a single CR2032 cell keeps maintenance rare.
See How You Actually Run
Paired with a compatible Suunto watch, a six-axis motion sensor measures cadence, ground contact time, vertical oscillation, flight time and left/right ground contact balance, so you can see how your form holds as speed rises and fatigue sets in. Up to 20 hours of rolling R-R memory sits on the belt itself, and your watch reads it back by timestamp to complete the record after reconnecting.
One Belt, Three Screens
Connect to as many as three devices at once over Bluetooth. A watch records the session, a bike computer shows live heart rate, and your phone runs the app alongside both. Every device receives the same live data, so a long ride or a triathlon brick runs start to finish on a single pairing.
