Perfect.

This heart rate monitor was designed to make it even better.

Most smartwatches measure your pulse from your wrist.

During:

• Sprint intervals

• Hill repeats

• Trail running

• Heavy sweating

• Strength training

the readings may become delayed or less consistent because wrist-based optical sensors are affected by movement and blood flow conditions. Dedicated arm monitors are designed to provide faster, more stable tracking during demanding workouts.

Optimized for athletes who seek precision, comfort, and performance.
