Use arrow keys to rotate the compass. Use A and S keys to rotate the bevel. But however you rotate the compass and bevel, the needle always points to North. Use the compass to find bearings to the objects, then click the objects to see how you did. Click the question mark for a challenge. To find the bearing to an object, rotate the compass (arrow keys) until the large arrow points to the object. Then rotate the bevel until the "N" on the bevel is aligned with the red end of the compass needle. When everything is lined up, the reading on the compass will be the bearing to the object.
