SUUNTO SMART HEART RATE BELT 2

Precision Heart Rate Monitoring for Serious Training

Take your training to the next level with the Suunto Smart Heart Rate Belt 2, an advanced chest strap heart rate monitor designed to deliver exceptional accuracy, comfort and performance.

Engineered for athletes who demand reliable data, the Smart Heart Rate Belt 2 combines accurate heart rate measurement, advanced running dynamics, heart rate variability (HRV) monitoring and Suunto ZoneSense compatibility to provide deeper insights into your training intensity and performance.

Whether you're running, cycling, swimming or completing high-intensity intervals, the Suunto Smart Heart Rate Belt 2 delivers the precision you need to train smarter.

ACCURATE HEART RATE & HRV MONITORING

Advanced heart rate sensing technology delivers precise heart rate and beat-to-beat R-R interval measurements, even during demanding workouts and rapid changes in intensity.

Designed to provide reliable measurements during movement, the belt helps athletes maintain accurate heart rate tracking throughout their training sessions.

SUUNTO ZONESENSE COMPATIBILITY

Unlock deeper insights into your training intensity with Suunto ZoneSense.

Using high-resolution heart rate variability data, ZoneSense provides real-time analysis of your body's physiological response to exercise, helping you understand when you're training in aerobic, anaerobic or VO2max intensity zones.

When paired with a compatible Suunto watch, ZoneSense helps you manage your training intensity more effectively.

ADVANCED RUNNING DYNAMICS

Go beyond heart rate with integrated running form analysis. A built-in six-axis motion sensor provides detailed running metrics when paired with a compatible Suunto watch.

Running metrics include:

• Running cadence
• Ground contact time
• Vertical oscillation
• Flight time
• Left/right ground contact balance

These advanced measurements help runners understand their technique, monitor efficiency and identify changes in running form as fatigue increases.

Running Form functionality depends on the connected Suunto watch and may require a custom sport mode, SuuntoPlus or post-workout analysis.

BUILT-IN MEMORY FOR UNINTERRUPTED TRAINING

The Suunto Smart Heart Rate Belt 2 features up to 20 hours of onboard heart rate and R-R interval memory, allowing it to continue recording when your watch is temporarily out of Bluetooth range.

Ideal for swimming and activities where maintaining a continuous connection may be difficult, stored data can be transferred to a compatible Suunto watch when the connection is restored.

The memory function is designed for use with compatible Suunto watches.

CONNECT TO THREE DEVICES SIMULTANEOUSLY

Featuring Bluetooth 5.4 connectivity, the Smart Heart Rate Belt 2 supports up to three simultaneous Bluetooth connections.

Connect your Suunto watch, compatible cycling computer and smartphone at the same time, allowing multiple devices to receive live heart rate data throughout your workout.

Secure, user-controlled Bluetooth pairing provides added connection security.

LIGHTWEIGHT, COMFORTABLE & SECURE

Designed for training comfort, the compact heart rate transmitter weighs just 12.8 grams.

The soft, adjustable chest strap provides a secure fit during running, cycling and other demanding activities.

The removable transmitter and machine-washable strap make cleaning and maintenance simple.
