I have only had mine for a couple of days, and have yet to take it on a cache hunt. From what I can tell so far, however, it is pretty nice. One thing that I dislike is that it only zooms to a scale of 100' as opposed to my Garmnin GPSMAP 76s which zooms right in to aound 10' (I think). The Topo software is about as acurate as MapSource. The color deinitely makes it easier to diiferentiate features on the display (especially on a map). It does seem to take just a bit longer to aquire satellites than the Garmin unit. I also wish it could connect with an external antenna. All in all, I do like it. I am looking forward to taking it into the woods!
