The heart of the compass is a high quality precision sapphire bearing for accurate and reliable results.
This compass comes with the popular 0 - 360 degree dial.
The M-73 compass features a prism sighting system for amazing 1/2 degree accuracy.
The compass is liquid damped for rapid sighting, and features five tritium light sources for both day and night use.
These Tritium light sources provide readability in total darkness for 10 years without external power or the need to "charge" using a flashlight.
