Subject: RE: Polar 625-xI like the 625. Works great for running and biking. You have to buy the speed attachment for the bike unless you get the 725 which includes the speed attachment. I have not tried the 625 for swimming but I understand it works as long as you can keep the strap from slipping off your chest.
I have not tried any of the other HRM options so my opinion is biased.
