Since my purchased via Amazon ergometer (Reebok Bike Titanium TC2.0) unfortunately has an inaccurate hand pulse measurement, I decided for a low-priced device with heart rate belt from Polar, because this brand is also listed on the ergometer. Unfortunately, I could not even Reebok Pulsar say whether this clock would work with coded transmission for the ergometer. Since Amazon is not a problem to jump "into the deep", I have this set FT2 ordered with T31 and no regrets. The functionality of the clock is enough for me and what makes me particularly happy (super maximum setting of maximum pulse with warning tone) and that the transfer from the belt works for ergometer and the pulse rate is now displayed correctly there.
