Suunto KB-20/360R G Compass

I use this for my work (Archaeology/Survey) and these compasses are great. Mine is about two years old, a little faded in color and some small scuffs on the edges, but sights like a dream. I originally bought one for $60 from Amazon, but I'm tempted to get another for backup.

There must be a prism in there or something to help gather and distribute light, but when looking through the peep, it is visible in very low light...surprisingly so really. Nothing special or feature-laden about the top of the disc that you view when just holding it. I have an older version of this compass (nothing has changed about it) and I don't really use it but comparing to my standby M3-D (now just M3), the KB does excel in low light, as long as the peep design is still useful for your application (i.e. if you can't see objects in the distance - open areas or not - then it may not be any more useful than another compass design. You will be able to see your bearing in the peep but maybe not direct it to a landmark).

There is no way to see it in photos but there is a bevel on the outer edge of the disc, concealed by the housing when you look at it but that is seen when looking through the peep. It's graduated in single degrees. This is not a trail compass really unless someone happens to be in a handful of situations while also needing to be very accurate with route marking or way finding (sailing is one good use I suppose). Honestly I don't believe I've ever been anywhere as a backpacker that this is needed, and there is the drawback of not having a clear baseplate with straight edges for use in conjunction with a map.
