Hi-
I have a nice small, waterproof gps (a older etrex vista, mostly used for kayaking) and a bike mount for it. Is there any reason I should get a bike computer instead? I'm always finding a way to get lost, so the gps is nice for the maps, and it can store current speed, max speed, etc. And I'm familiar with using it, since I've used it kayaking for years. The gps doesn't record cadence, of course, but do most inexpensive bike computers? I'm sure the gps is heavier (5.2 oz with batteries).
thanks!
