[QUOTE="Packrat 6, post: 1025250, member: 80288"] Just an additional note about the compass I loaned out to what's his face. I stated the that the civilian version of what I loaned him was called a hand transit, BUT there are several different kinds of hand transits. BTW, they are called [B]Brunton[/B] Hand transits if looking them up online. The military types (M-2) are usually divided into mils, with the bezel ring (the numbered ring at the perimeter that you determine your azimuth from) showing 6400 mils to a complete circle. This is a metric unit where 1 mil = 1 meter wide at 1000 meters and is used extensively in Artillery Fire Control among other things. Also, most military maps are in meters. Well, except for maybe the Air force which is a little slow when it comes to LAND navigation.....AND the navy which has Very little use for Land Navigation....:) The Army and Marines have their Feces consolidated! There is also a hand transit which the Bezel ring is divided into 4 each, 0-90 degree quadrants, labeled North, East, West, and South and is for specialized usage. I have been told that one of these uses is for use in mines where the angles of a cross tunnel don't need to be given in degrees more than 90 Degree's, but somehow this doesn't seem right. Maybe someone else knows how this one is used. The type that I have and which was unusual for the Army,has the Bezel ring divided into 360, Degree's, Minutes, and Seconds, although the minutes and seconds are not marked on the ring. Generally, this is what you want., unless you are living in a metric country and they use the mils...??????? If you decide to buy one of these type compasses, which can run into the Hundreds of Dollars, make sure that you check to make sure you have the correct Bezel ring. Also make sure it has the declination offset adjustment, usually geared, the compass needle lock which pushes the compass needle up against the glass to lock the needle in place when traversing rough terrain and not in use, (one of the reasons I hate cheap compasses, they will get you killed when the needle dismounts from the spindle) and a GOOD carrying case, usually heavy leather or heavy plastic. which won't damage the compass if you fall on it.
