This closed-case compass is ideal for hiking, exploring, and boating. The housing is made from zinc-aluminum alloy with a painted bronze finish; it has an integral sighting wire in the lid, used in conjunction with a built-in magnifying lens for reading bearings. The directional needle has mineral oil damping.
Comes with complete instructions for use plus a magnetic variation map, so that you can determine the difference between magnetic north and true north for your area of North America.
Great value in a compass.
