The RP3 App is compatible with all Bluetooth heart rate monitors. This includes chest straps, arm bands and watches that can broadcast heart rate via Bluetooth.
To connect a heart rate monitor, simply tap on devices and connect it to the display in the same way you would connect a machine. Click here for more information.
Our recommendation would be to use a chest strap heart rate monitor for use on the RP3 as they provide a more reliable and accurate read out for rowing compared to wrist or arm monitors.
Our favourite heart rate monitor is the Polar H10 chest strap. It features easy bluetooth connection, accurate measurement and can support dual device connection if you wanted to connect to a sports watch or other device along with your RP3 during a session.
Our budget recommendation would be the Wahoo TICKR chest strap. It also includes many of the features of the Polar H10 just without the dual device connection. The other advantage of the Wahoo is that it is much less expensive.
