WaterRower Internal Heart Rate Monitoring Kit ANT+

The WaterRower Digital Heart Rate Monitoring Kit, uses ANT+ wireless technology to accurately measure heart rate and display it on the WaterRower S4 Performance Monitor. 

The kit includes:
(1) Digital Chest Belt ANT+ Transmitter 
(1) Internal Digital ANT+ Receiver 

This kit is compatible with the Series 4 Performance Monitor and must be connected internally

Digital heart rate monitors have a transmission distance of 1.5 meters (as opposed to 1.0 meters for analogue monitors, such as Polar). This allows the receiver to be placed internal, or adjacent to the monitor removing the need for unsightly extension cables. Further, the use of digital technology improves accuracy and reliability. 

ANT+ digital wireless technology greatly improves the range and accuracy of heart rate information and is widely adopted by industry leaders such as Cardio Sport, Garmin, Timex, etc.
