Brought but never used so brand new old stock! Will also work on concept2 skiErgs and bikeErgs This monitor is a quality monitor, the belt is flexible and comfortable to wear, *on the concept 2 pm 2/ 3 monitors you will need the optional receiver to connect to the monitor. (I’m sure I have one that I could sell separately) you can then see your heart rate on the monitor screen. If you have a pm4 or pm5 monitor this belt will connect directly with the monitor (as they now have the receiver built into the monitor) Any questions please ask
