Finis unveiled the AquaPulse Heart Rate Monitor for Swimmers.
The Finis AquaPulse heart rate monitor is a small slender workout accessory built for swimmers looking to maximize their workout through heart rate training.
The gadget is featuring Finis' patented bone-conduction technology and a unique infrared heart rate sensor.

The FINIS AquaPulse uses an accurate infrared sensor that clips to the earlobe in order to pick up the swimmer’s heart rate. By measuring the light pulses due to capillary blood flow in the skin, the sensors calculate the number of beats/minute (b/m) that the body is working. The internal computer within the AquaPulse then audibly communicates this heart rate to the user using the revolutionary Bone-Conduction Technology, a unique sound transfer technology that communicates sound vibrations through the temple bone to the inner ear. Humans normally hear through air conduction, but because there is no air underneath the water, bone conduction provides the clearest sound quality possible.
By simply turning the unit on, the user’s heart rate can be sensed and automatically communicated. All functions are integrated into one small unit that the user clips on to their goggle strap and rests on their temple.

The AquaPulse heart rate monitor consistently communicates the heart rate every pre-set time period. The user can program this time period from as little as 20 seconds up to 5 minutes, allowing for continuous feedback during training. It also features an instantaneous heart rate function. The user can simply press a button at any time and their most current b/m will be communicated.
The Finis AquaPulse will be available in May for $139.99.
