A liquid-filled baseplate compass with a rotating bezel and adjustable declination.

Shipping: calculated at delivery

The Compact Baseplate Compass has a liquid-filled capsule that steadies the needle quickly and damps swing. The clear acrylic baseplate carries millimeter and inch scales along its edges and 1:25,000 and 1:50,000 romer scales for plotting on topographic maps.

The rotating bezel is graduated in 2-degree increments. A declination adjustment screw lets you set the local magnetic variation once and then read true bearings directly. A magnifying lens and a lanyard hole are built into the baseplate.

The needle is balanced for the Northern Hemisphere. Weight is 35 g.

  • Declination screw is worth it

    Setting declination once and reading true bearings directly removes a step and a source of error. The capsule has no bubble and settles fast. Romer scales line up with my maps.

  • Bezel turns a bit freely

    The bezel rotates without much resistance, so I double-check it has not shifted in my pocket. Otherwise an accurate, no-frills compass. Northern Hemisphere only, as stated.
