Finis Aquapulse Heart Rate Monitor -
Never stop to check your heart rate again. With the AquaPulse Heart Rate Monitor your current heart rate is verbally announced while you swim. Simply slip the AquaPulse inside your goggle strap, attach the soft rubber clip to your earlobe, and go swim. Using an infrared sensor to monitor capillary blood flow, your heart beat is detected through your earlobe. The heart rate is then audibly communicated to you in real time, where the information is transmitted directly to your inner ear via Bone Conduction Technology. No ear buds, cumbersome chest straps, or watch devices are needed.
