Not designed to be used as a stand-alone compass, this compass is designed to be used in any manufactured product you can dream up. The total diameter is 20mm (just over 3/4 inch). The operating temperature ranges from negative 10 degrees F to positive 110 degrees F. The capsule features a compass card with green cardinal letters. Water resistant to 10 feet.
It fits perfectly inside the D.E.W.C.'s 21mm inner compartments. Just use a piece of double sided tape or a drop of glue, center the compass in an end cap and you're all set.
