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.
Summary: Comments about Garmin GPSMAP 60CSx Portable Navigator: I'm lost without checking a map or having a 100% reliable GPS. Garmin seems to be the best for reliability. This model is best when I'm not in the car, or when I borrow my neighbor's boat for a day.
Pros: Compact, Easy To Read, Easy To Set Up, Long Battery Life, Reliable Performance, Strong Construction, Versatile
