Polar Ignite 3 is equipped with Polar Precision Prime™ sensor fusion technology, making it suitable for tracking heart rate during high-intensity interval training (HIIT) workouts. This technology combines optical heart rate measurement with skin contact measurement to ensure accuracy, even during the most demanding training sessions.
For best results during such workouts, it's recommended to wear the watch slightly higher on your wrist and tighten the wristband to minimize movement and maintain good contact with the skin. This positioning ensures the most reliable heart rate readings during intense activities.
Additionally, if you're seeking supreme accuracy, especially in sports where keeping the sensor stationary on your wrist is challenging, you can also pair the watch with a Polar H10 chest strap, which is known for its responsiveness in interval training.
