Polar Verity Heart Rate Sensor

Healthy cardio is about heart rate, not lap pace. Take the guesswork out of your swims with the Polar® Verity optical heart rate sensor add-on. 

While connected to the Polar Verity, the Delphin can produce real time vocalized BPM updates as you swim via Delphin's Lap Tracking app. 

When you choose the Verity add-on, you will receive the heart rate sensor with built-in clip and a charger for the sensor in addition to the standard Delphin Bundle items. Goggles are not included.
