The uncoded heart rate transmitter (transmitter) "T31" showed the traing with the "Crane Circular S8 Studio ergometer" (a sold by Aldi / Hofer product) significantly less susceptible than the damage caused by the eddy current brakes interference than 4 tested competing products. This significantly cheaper devices - including the "Crane -Pulsuhr" (also at Aldi / Hofer to buy) are in part (ie transmitters and clock coordinated by encoded signals to avoid interference from adjacent transmitters - eg while running in groups) and are coded not recognized by the computer of the ergometer. In part, the display on the included heart rate monitor is so greatly disturbed that the pulse value from 0 to> 150 and back within a few seconds and varies not get away with it for a pulse-oriented training in question. So far so good. It is annoying that the Polar transmitter completely einschweisst so without violent intervention - for example with a fine saw - the battery can not be replaced. What actual among other brands very easily without damaging the seal possible and in the description specifically recommended wird.Angeblich keeps the battery 2 years. So you have to take the battery replacement a more than 20 times more expensive channels to perform the procedures. The tune!
