    Garmin cadence magnet

    I just got a Garmin 305, and I'll be using it on a few different bikes. I know I can buy an additional cadence sensor for ~$40, but I'm thinking about just moving the sensor from bike to bike since its just zip-tied on.

    Can I just attach any old magnet to my crank to get the cadence sensor to work?
    Taiwan could probably TIG weld a ham sandwich to a dictionary these days, but its been a while since they were doing brazing.

    How many zip ties are you going to go through for that? I ordered another sensor. I admit at $40 its a bit expensive. I wonder if they could cut out some money if they made it cadence only?

    I noticed when I tried this it may depend on how strong your old magnet is. When I tried another cadence magnet I had from a previous computer on my garmin it was not strong enough to trip the sensor. The garmin magnet is a pretty big/strong unit so you may have problems if your old magnet is not of similar strength.
