Hey, flyefisher... I have the same Polar S120...

Have you gotten the Recovery function to work?

Theoretically, in order for that to kick in, you have to press & hold the red button on the face of the wrist unit. If you press the same button quickly, it records a lap.

I've tried many times to actuate the Recovery timer, but it records a lap nearly every time instead, no matter how hard I press the darn button. The only two times that the Recovery thing has worked, I was running. Would be nice if it was more reliable in that regard.

Any thoughts?
