i really don't think there is one that works well for all. as the hand helds for geocaching are wonderful and all but small screens for in car. the in car ones are not likely to be durable enough for geocaching.
however this into sports line might be good motivation for myself to keep pushing and going forward.
last year i lost 75lbs by watching what i ate and getting active. didnt go anywhere over the winter and no where so far this year either. got sidetracked by the decision to make this move and well i have no one to blame but myself.
but have started to get active again.

i would give up the car one to have one work for the geocaching and on the bike/hike thing

thanx for the info
