Uses state of the art ANT wireless technology to accurately measure heart rate and display it on the WaterRower monitor 

The kit includes:
(1) Digital Chest Belt ANT Transmitter 
(1) External DigitalRower ANT Receiver 

This kit is compatible with Series 4 monitors and plugs in externally. 

Digital heart rate monitors have a transmission distance of 1.5 meters (as opposed to 1.0 meters for analog 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 becoming widely adopted by industry leaders such as Cardio Sport, Garmin, Timex, etc.
