A well thought-out adventure racing compass. It has a magnifier, and common USGS series scales built into the base plate. It adjusts for declination with a small key the same way that a Silva Ranger works, The base plate also has notches where the lanyard ties in so that it can be layed entirely flat.
The only drawback that I see is that the hachures are spaced every two degrees and relatively thick and fuzzy to read. May result in imprecise readings.
