This is an inexpensive Map Compass that works. Has scale, magnifying glass and hair line allows for accurate sighting. Because of the low price I recommend these as a back up to you other compasses. Put it in your pack or cargo pocket any time you out and about in the wild. I am a back up kind of guy and I have back ups for my back ups because Mr. Murphy is the law the wild. Also makes a great gift as a first compass for youngsters as we know how they loose things.
