The PM3 tracks distance, pace, watts, calories, and stroke rate. It does not have Bluetooth, so it will not sync to apps. You can buy a PM5 from Concept2 and swap it in later with two screws if you want that.
Concept2 still supports these machines and sells every replaceable part.
Cash at pickup.
Pickup only, and you will need to carry it out and load it yourself. It separates into two pieces without tools, and two people can move it easily. Bring help and a vehicle that fits it.
