Hello guys/gals, I've had 2 handheld Garmin GPS units in my life: GPS 12xl Etrex 20 (I still use this one - it was a nice upgrade from the 12xl) Usage: Casual trail hiking (woods), marking fishing spots. Most of the time, just marking and returning to waypoints - or finding my way back out of the woods via the cookie crump trail (route?). I've been mostly happy with the Etrex 20, except for compass and am reasonably comfortable using it, I just figured a slightly larger screen, a 3-axis compass/altimeter etc. would be a neat idea. Example: I have been frustrated when in a boat trying to navigate back to a waypoint and I have to get moving first, before the compass shows the proper direction. Not a deal breaker - but definitely would be handy to solve that issue. I was eyeballing the 64st, or 66s. Not going to consider the Oregon 700 - too sensitive screen, or wonky when it rains? Primary concern would be reliability, which of these devices to your knowledge is generally stable these days? I've read issues about the 66 series having issues with battery and/or geocaches disappearing, but maybe those were earlier firmware versions. thanks in advance! Mike
