All our BoB's have fisheye compasses on the shoulder for general bearing, and work well. I am not an expert with a compass. (city boy) I bought a "lensatic marching compass" off of amazon a while back for around $10-man did it suck. It looked g.i. but to get the needle to find north, nearly had to float it in still water or it would hang. So, instead of buying several and finding out what works... What do you guys recommend for around $10-$40 for map reading and navigation (will be buying two). Clear base would be good for maps, and absolutely a window or wire for aiming. Ideas on an instructional book on wilderness navigation would be nice too.
