SightMaster sighting compasses offer the convenience of two compasses in one as a hand held unit, or as a sighting model. A 10X magnified, precisely ground sighting lens with a diopter sight allows compass estimations to 0.25°. Dial shows both forward and reciprocal headings, incremented by 0-360°.

It includes a tripod mount for use with our tripod and monopod accessories, and a sine table for quick reference. Two Models Available: SM360QLA - Scale: 4 x 0 +/- 90 degrees.
