This is a demonstration baseplate compass that is big enough to hold up in front of a classroom and be seen by your students. You can demonstrate common compass skills including:

• Orienting yourself and your map with North and the cardinal directions
• Sighting a bearing to a distant object
• Traveling along a heading
• Plotting a bearing on your map

The compass can be adjusted for declination and grid variance, and you will be able to show your student how to do this and what their compass should look like when correctly adjusted. Just like in a real compass, the orienting arrow is on separate layer from the orienting arrow and protractor dial. There are angular markings to help position the orienting arrow at a fixed angle from the orienting lines and the protractor dial. This compass uses a dot of velcro to fix the adjustment position.

Please note this is not a functional compass. The needle is not magnetized and will not align itself with magnetic north.
