What kind of maps can I use with this compass?
The compass is designed for use with maps that have scales of 1:25,000 and 1:50,000, as it includes the necessary scales for distance measurement.
How do I attach the lanyard?
The lanyard is detachable and can be attached by looping it through the designated hole on the compass housing.
How do I clean the compass?
Use a damp, soft cloth and mild soap. Avoid harsh chemicals or abrasive materials that could scratch the baseplate or damage the markings.
Can this compass be used in the Southern Hemisphere?

How do I use the magnifier?
Position the magnifier over the area of the map you wish to examine closely. This will magnify the details, making them easier to read.
Troubleshooting
Needle sticks or doesn't move freely.
Ensure the compass is level. Check for any obstructions, such as dirt or debris, and clean the compass if necessary. Avoid using near metallic objects.

Setup, Compatibility & Care

Rotate the compass housing until the orienting arrow aligns with the map’s north. To care for your compass, store it in a cool, dry place away from direct sunlight and extreme temperatures. Clean the baseplate with a soft cloth and mild soap if needed. Avoid dropping the compass, as this can affect its accuracy. Check the needle's movement regularly to ensure it is not obstructed.
