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.
The heart rate announcements are made regularly in 20-second, 30-second, 45-second, 1-minute, 2-minute or 5-minute increments. Push the “Instant Heart Rate” button to hear your last reading again. Complete with a lithium-ion rechargeable battery, you can use the AquaPulse from five to eight hours depending on the interval setting. Simply plug the integrated USB directly into a USB port on your computer to recharge.
