Geographic engineer compass FLT2
It is all your need for both slope/height measurements and compass bearings. It features both a sighting compass and a sighting clinometer in a solid cast aluminum body. Optics at either end allow you to peer into the compass for horizontal measurements, or the clinometer for vertical measurements. The clinometer scale is in degree and percent (0-90°, 0-150%) while the compass scale is azimuth (0-360° with reverse scale). Both the clinometer and compass are graduated in 1° /1% increments and each is individually calibrated. Other features of this Compass/Clinometer are an inch and mm ruler, cosine and cotangent tables, lanyard, and a carrying bag.
