|Cordless cyclecomputer interferes with HRM||Hovis|

|I'm using my new HRM on my rollers this weekend because a storm has blown in, and the HRM (Polar S3 I think) says I'm doing 220 bpm, while my Cateye Cordless 2 says I'm doing 0 mph.
Because I don't really want to know my roller miles (they don't count as real miles), I move the magnet away from the sensor on the wheel, and my HR returns to my target (<160) and all is well.
Do you have to have an HRM with coded transmissions to stop the cycle computer affecting it? Will doing so also allow the cyclecomputer to tune in to its sensor rather than that of the HRM (which I'm guessing is confusing it - on a road ride without the HRM, the Cateye works great).

|Actually, the Cateye is the only cycle computer I know of which has this problem. Why Cateye chose to develop their cycle computer to transmit on the same frequency as ALL heart rate monitors, I will never know. Unfortunately, there is very little way around the problem. You can try keeping the HRM on your wrist as far away from the computer as possible, but this may not work.
The only real solution is to go with another wireless or any wired cycle computer, as this will be cheaper than going with a high-end coded heart monitorwhich still may have problems. Anyway, Specialized, Vetta, Sports Instruments, CycloMaster's and others wireless cycle computers all function on a difference frequency than cateye and heart rate monitors and should cause you no problems.

|I found that the Catee Cordless 2 interfered with my Polar HRM as well. I cured the problem by getting a Vetta RT-88. No problems in many thousand kms.|
