This device, striking in its simplicity of function, is one of the coolest ideas I’ve seen an a long time. Bushnell’s BackTrack GPS device is cheap ($60 on Amazon) and basic, functioning much like a stop watch for your location. You press a button to mark your location, and you press a button again to start pointing you back to that location. I’d like to see something like this get cheaper and ubiquitous allowing, for example, parents to give one to each child, or travelers on a budget to find their way back to a key location.
This is a very clever innovation in what’s fast becoming a crowded GPS market.
