Dan/EdT--The Brunton is a great compass. I can plot my position within a few meters on my quads taking UTM from my GPS. Been very helpful when faced with multiple trails exiting a stream/trail crossing point where only one is shown, and not sure which to take. Mine is called an Eclipse, but looking at the pix on the Brunton site, I can't find any difference between mine and the new one...been using this one about 5-6 years and love it. Guessing it is an older version of this new 40B. Take care out there. Best. Joe
