jcjordan said:I will second that. Polar-Pursuit in Adelaide (Polar distributer in Australia) recomend that you wash it every couple of times you use it with old toothbrush; they recomend that you scub the silver conections between the centre part and the strap and the the sensor parts of the strap. All I do is take it into the shower and give it a wash after a ride.
I just got 725x (replacing my lost 710) and the strap is different. Soft material with a separate transmitter centre - not like the single plastic chest strap of the old model. The instructions suggest washing it but how long will this thing last going through the machine? I think I'd prefer to just wipe it after a ride but is this sufficient? Damn them! I liked the old strap!
