H7 Bluetooth Heart Rate Sensor

Increase your physical fitness levels by targeting your ideal heart rate with the Polar H7 Bluetooth Heart Rate Sensor. Ideal for cycling, running, and swimming, the H7 won't restrict motion or cause irritation when you're pushing your limits. This wireless heart rate sensor fits across your chest with its soft-wearing strap, feeding data via Bluetooth to compatible smartphones and fitness watches. The submersible design maintains accurate heart rate measurements as you swim laps in the pool or practice your breast stroke across icy-cold lakes. Please note, the H7 works with many Polar watches equipped with Bluetooth. It's also compatible with iPhone 4S, Galaxy S3, and newer smartphones running the Polar Beat app.
