soooo, does that mean that if i go ahead and purchase a handheld model to use -- that it will likely respond the same as the nuvi unless i also purchase the topo maps as well? I do realize that people move caches, get coor wrong, etc., and I actually like the challenge that the nuvi gives us by only getting us "in the ballpark". But I am trying to justify purchasing a handheld to use for caching as we were getting pretty frustrated with trying to locate a needle in a haystack when the nuvi only gets you to within 50 feet or so. And you are right, the nuvi does lock on the roads -- also presenting another very obvious challenge when trying to find a cache in the woods. We did try using the pedestrian mode to overide that problem, just didnt seem to help much. Just trying to figure out, before i spend the money, whether a handheld will make that much difference in trying to locate caches and why. Thinking about a etrex legend or vista hcx.
