I use the 60cs all the time. I rarely use the electronic compass feature. I find it unreliable. An old army compass is way better. I DO use the gps moving compass all the time. As long as you are moving around, the needle points to the cache, pretty accurate. I compare it with my 12map and my 76map and all seems about the same. The electroninc compass works OK some of the time, but I mainly leave it turned off.
Saves the batteries to leave it off too.
