Wireless Devices

I am currently using a Polar S520 to track a lot of cycling data, including cadence information. I would like to track altitude gains on my rides so I need an Altimeter. Is there a problem using a wireless Altimeter when I already have two wireless devices linked to the Polar S520?

-- Unfortunately, unless Polar sells what you are after and can assure compatibility, you might have to experiment with a specific device to find out (if the altimeter requires any "wiring" at all). A pure altimeter is essentially a barometer and does not need to have a wheel sensor. A gradient gauge, on the other hand, uses altitude changes plus distance changes to calculate gradient and would need a wheel sensor.

I have heard warnings about wireless devices interfering with one another. I have a wireless Ciclisport bike computer with an altimeter, gradient gauge, thermometer, etc and a wireless dbase heart monitor that work fine together.

Thanks for your input. I am considering a Ciclisport CM 414 Cyclecomputer with an altimiter. It's used, and the party selling it can't answer my question. Unfortunately we're not in close proximity so I can test it first. Thanks again.

--Mine is a Ciclosport 414, now about 14 months and 6000 miles old. I have occasionally had problems with it. I can't figure out why, but occasionally it will refuse to read from the wheel sensor. It's not a battery problem, more likely the bar unit interface. It's been working fine for the past month, so maybe it just didn't like really hot, humid weather. (It's German, after all.) Other than that, it offers a lot of nice features for a price. I paid $120. The newer version is the 434 at $139 or so. Don't pay more than $60, I'd say. Otherwise, go for the new one.

As I said, it doesn't interfere with my HRM.

Good luck.

Thanks again, The seller is asking $60.00. I think I will give it a go.

Lots of people use HRMs and wireless computers at the same time. The chances of the two being on the same frequency and interfering with each other are very slim.
