I recently purchaced a Magellan Sport Trac Pro. So far,
I am very happy with it. Bought it because it's the only handheld with 6 meter accuracy. I like it better than my
old Garmin as it's a bit simpler to use. I can't say
how long it will hold up as I haven't had it long. The
unit is advertized as "waterproof and it floats". My Garmin
said the same thing though,it only lasted 18 months.
