Summary: I originally purchased this GPS for geocaching and hiking in the High Sierras, but now I use it for adding up the miles I walk during the week. I have had this for over 10 years and it is the most accurate GPS I know of.
Summary: I have owned my 60CSx for upwards of 10 years now, and have nothing but praise for it. To be honest, I've never used many of the features available such as maps, but simply marking waypoints has served me extremely well in hiking and off-road biking activities.
Summary: It has been a few years since I bought this unit and I expect that refinements in electronics have made hand held GPS' more accurate. When I used the 60CSx if I could get within 20 feet of a target I was doing very well. Typical error runs around 40 - 50 feet.
