[QUOTE="Hugnot, post: 2241647, member: 115658"] For years I was sort of connected to compasses. Now my 2010 Honda has a compass, it can be corrected for deviations from the agonic line, if I cared to do so. I only look at it in parking lots to get shade advantages when the sun comes up. In the past I used a magnetic compass & barometric altimeter to locate topo features for map making. In the USN there was a magnetic compass on the vessels bridge complete with 2 iron balls (horizontal magnetic field correction) and iron rods (Flinder's bars, vertical magnetic field correction) and used with deviation charts. The compass was a backup for the directional gyro system. Now, hand held GPS devices can be had. My GPS device does not work so good in deep wooded places. [/QUOTE]
