I have used an eTrex Vista for the last 3 years with the usual complaints, poor reception under tree cover, I loose reception just from having it on my belt. The pros are all the advance features, the memory, altimeter, mapping features, flux compass, and the size, that one is a double-edged sward since a complaint is the screen size. These units are built like a brick. You can’t imagine the number of times I have dropped it in the last 3 years. I even lost it one time while I was bush whacking and found it a month later between two rocks by a stream, the case was soaking wet. I wrung the case out, toweled off the unit changed the batteries and continued to the cache I was after in the first place. When I replace it will be a new Map76s. It has the three important features for geocaching I want. Larger screen, external antenna, and waypoint averaging.
