>Low-Light Hiking Compass
Uhh.. what makes this a "low-light hiking compass"? Or did you mean it's not too ultralight or mediumlight, so it's just lowlight?
FeebleOldManThis is also confusing to me, but I would venture that the face of the compass is reflective to some degree so that it is easy to read in cases where you do not have enough direct light to shine on it, such as early in the morning/ late in the evening or under heavy foliage. I don't know how this would compared to a luminescent compass but it's nifty if that's the case.
FeebleOldManThere 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).
