Big subject, the compass. I went thru several and am presently using a Suunto auto compass sold by Aerostitch. Initially I mounted it on my windshield but since I ride off road 50% of the time the vibration broke it fast. I got a new one on warranty and disassembled the base to make it
flat on the bottom and added a piece of velcro so I can stick it on my tank bag. It is a fairly large liquid capsule compass. This compass has internal magnets so you can adjust it for the magnetic interference of the bike. It works fairly well when correctly adjusted and I like it since it provides a general direction of travel and helps if you get turned around like I sometimes do in either urban or off road situations. With the velcro I can pull it off and stash the unit when not needed. You need to carry an extra compass to set it in case it gets knocked out of adjustment. Hey, it isn't perfect but at least I don't do the GPS shuffle when I stop trying to find which way north is. To be honest I use it most on the road when I get turned around and don't go 20 miles out of my way. Bill.
