Does anyone know of a car compass that really does work in the car?

Answer 1

Any store bought compass will work fine, but you have to be careful in how you place it. Just plopping it down on the dashboard isn't enough.

-- First take the compass outside and far from any metal then get a reading. This is you base reading.

-- Second go into your car and turn the engine on, run the fan as well. Then move the compass around until you get a base line reading that matches the one you took outside and mount the compass there. Now you know that the electrical field of the controls, and the metal of the car won't throw your compass off.

If you can't find a good mounting place then get some little magnets and make ballast. Modern ships are huge chunks of iron with a lot of electrical fields, yet you still need a compass. So the compass is mounted in the ship's ballast. The ballast is made out of brass, which doesn't conduct a magnetic field as well as iron. There are two balls on each end which hold magnets with the compass in the middle. When the compass is mounted the magnets are moved or changed to get the proper balance so the needle points true.

You can do the same with tiny magnets that you attack to your compass case. Simply balance the compass, the car, and the magnets to align it properly.
