Comfort Belt Dual ANT/Coded offers reliable heart rate tracking for Suunto watches and gym gear
What Our Gearhead® Experts Are Saying:
"I’ve used the Comfort Belt Dual with my Ambit2 for years—it’s super comfortable and delivers consistent, accurate heart rate data whether I’m trail running or on a stationary bike. Just remember it’s not compatible with the newer Ambit3 or smartphones."
When accurate heart rate data matters for our training, we count on the Suunto Comfort Belt Dual ANT/Coded to keep us dialed in. Designed for compatibility with a range of Suunto heart rate monitor watches and gym equipment, this belt delivers real-time readings through both ANT and coded analog transmission.
It’s built for comfort during high-output sessions, with a soft, adjustable strap that stays secure and barely noticeable—even during long runs or indoor intervals. While it doesn’t sync with smartphones or newer Suunto models, it’s a perfect match for classic devices like the Ambit2 or M-series watches.
