Just wonered if it's possible to use a wireless computer AND a HR monitor on your bike. Would the computer cause interference with the monitor? Or does it all depend on the makes?

I have a Sports Instruments SI90HR which is wireless & has both computer functions and HR functions. The HR stuff is pretty basic & it works pretty well, although I do get electrical interference which cause the unit to stop or act erratic. SI also has other units. They are at

I think that some manufacturers are recognizing that interference is annoying & begining to build with FM freq responders (Timex does). The other thing with getting a combo unit is that it simplifies things on your bars.

I use both the Polar S710 and Supergo HR monitors at the same time. I wear the Polar chest strap, so only the Polar HR function works. i was going to take the Supergo off when i got the Polar, but found that I like both screens since the Polar's speed is hard to read. the Supergo's ride time funtion is also more accurate as it doesn't go to sleep if you stop for an extended period. they each have their own magnet on the front wheel and i have no problem with interference. both remain accurate
