Upgrade your Concept2 indoor rower to a PM5 today - RNNR by Chris Abraham
If you have a Concept2 erg and haven't retrofitted your Model A, B, C, D, or E Indoor Rower to the PM5 performance monitor, I most highly recommend the splurge of $160-$180, depending on the model of your rowing machine. Turnkey wireless everything you'll need, including ANT+ and Bluetooth Smart. S
