Been looking into GPS systems as SW has an old Garmin unit strapped to his Dirtsurfer, and I'm currently using a Halfords £12 bike computer. Mine gives me max speed (so far 40MPH recorded), but as part of our new "official world speed record" we (we me actually) need to be able to record and verify it on GPS. Found this one: a GARMIN FORETREX 101 Personal WRIST MOUNT GPS for £68 + 15 postage. Thats great value as its normally over £100. Its also fully waterproof and wrist mounted. We decided to order a couple and have direct comparisons then.
