The big brown truck brought me a new Bushnell Backtrack Point>5 GPS Friday afternoon. It locks up (finds its location) fast, has a nearly Marine-proof interface, and useful data screens. I was horrified with the accuracy of the built in digital compass. After carefully following the calibration instructions several times I pretty much decided the thing was worthless for getting a reasonably accurate vector back to a stored point or a usable bearing on a landmark. Next I went to the web site and looked at the online manual, which was just a copy of minimalist 9 page brochure which came with the unit. I had just about decided to send the thing back when I stumbled onto Bushnell’s “BackTrack Digital Compass Calibration Tips” video. By combining all three techniques demonstrated in the video I was able to get useful accuracy from the compass / trackback arrow. I haven’t sat on or dropped my unit yet so I can’t say how robust this thing is going to turn out to be, but for the time being I plan to leave my Garmin in the truck and use the Backtrack to find my way around in the field.
