I used to be a true believer in the Lensatic compass, until one failed me in the field and I got off in the wrong direction, in the dark, etc. Anyway, Its a good piece of gear, designed to be used with MGRS maps and in military scales (i.e. 1:50 and 1:25).
The thing that I dont like about them is that they are big and bulky, and it is difficult to get lensatic compasses with tritium so you dont have to shine your flashlight on it at night.
I personally use a Silva explorer. I use it when I go camping and when I am in the field. Its lighter and fits in a breast pocket and disappears. The thing that I like about it the most, is the ability to quickly spin off an azimuth and then being able to use BIG FAT ARROW to line up with BIG FAT DOTS and maintain my course. Is it tactical? No, but if I am killed because someone sees my clear plastic compass then I have bigger issues to deal with.
just my two cents
