The Zone 3 Omni-Sight Sighting Compass from Brunton is designed for bearing readings in the MS zone for southern regions. It has a spot-through design with a 10x adjustable lens for viewing. It also has both forward and reciprocal bearings along with 90° quadrants, a 360° azimuth, and a 6400-point MILS. This is all displayed via a rare earth magnet that resists interference and will not lose polarity.

For use in low-light conditions, the Omni-Sight features an illuminated readout by the use of light piping. Also, for maximum durability it is encased in an anodized aluminum housing with a rubber bump cover. A leather case is even included for additional protection.
