The lensatic compasses are accurate, rugged and reliable. Durable OD green aluminium case, with metal hinges, is both waterproof and shockproof. Azimuth is graduated in 5-degree increments, while the outer dial is graduated in mils. Includes built-in magnifying lens, finger loop and nylon lanyard.
These military-grade compasses are ideal for camping, hiking, sports, meteorology, or any outdoor activity. Accurate directional course plotting with night vision luminance. The bright green fluorescent vials enables you to read the compass at night without an external light source.

The lensatic compass consists of three major parts: the cover, the base, and the lens.
Cover. The compass cover protects the floating dial. It contains the sighting wire (front sight) and two luminous sighting slots or dots used for night navigation.
Base. The body of the compass contains the following movable parts:
(1) The floating dial is mounted on a pivot so it can rotate freely when the compass is held level. Printed on the dial in luminous figures are an arrow and the letters E and W. The arrow always points to magnetic north and the letters fall at east (E) 90° and west (W) 270° on the dial. There are two scales; the outer scale denotes mils and the inner scale (normally in red) denotes degrees.
(2) Encasing the floating dial is a glass containing a fixed black index line.
(3) The bezel ring is a ratchet device that clicks when turned. It contains 120 clicks when rotated fully; each click is equal to 3°. A short luminous line that is used in conjunction with the north-seeking arrow during navigation is contained in the glass face of the bezel ring.
(4) The thumb loop is attached to the base of the compass.
Lens. The lens is used to read the dial, and it contains the rear-sight slot used in conjunction with the front for sighting on objects. The rear sight also serves as a lock and clamps the dial when closed for its protection. The rear sight must be opened more than 45° to allow the dial to float freely.
