Summary: This thing sounds great and maybe I'll get it to work better in the woods, but in a parking lot this thing is a bit of a joke. It doesn't point north, it doesn't point to the waypoints most of the time, BUT the distance does accurately decrease as you move closer to the target.
Summary: I recently purchased a Back Track at a big box store. I really wanted to like it, but it was unreliable. Like another reviewer noted, my marked locations drifted significantly (30 to 50 yards) over short periods of time.
Summary: Not accurate at all. All 3 of my markers drifted 50 yards NNE overnight, causing me to momentarily get lost in a thick forest wilderness. I set a marker, walked a quarter mile, walked back, and it was 30 yards off. No telling if it drifts farther than that over longer distances or time periods.
