Interesting topic indeed. I am new to Geocaching and using my eTrex Venture HC. I did a set of new hides recently and had to go back to one of them because I forgot to leave a log in it. Using my coord.s and knowing exactly where it is I went right to the spot. My eTrex showed me being 10 feet away even though I was standing exactly on the hiding spot. That got me wondering about the accuracy of these things.
Another thing I have been wondering about is is it worth it trade up to a better model of GPS if accuracy doesn't get any better. Are the extra features worth the cost ?
