How to Troubleshoot a Compass

Compasses are some of the world's older navigation devices. A needle on the compass points the way towards magnetic North, which for navigation on most of the planet is close enough to true North. A regular compass consists of a needle or rotating compass card floating in a transparent chamber filled with a liquid. There are also now digital compasses available on the market. Troubleshoot a compass by looking for a few common indicators.

      Look for any bubbles in the compass liquid. If there are any bubbles this indicates a leak in the sealing of the compass which can contaminate the compass fluid and cause the needle to not turn properly.

      Check that there are no magnets near the compass. A magnet will interfere with the compass pointing towards magnetic north.

    • 3

      Re-calibrate the compass if it is digital and not pointing north. Follow the directions specific to the compass to re-calibrate it. If it is still not giving a reading then return it to an authorized repair facility.

      Hold the compass level when navigating. Holding the compass at a tilt can cause the needle or card to float incorrectly. You should keep your compass level when turning to ensure that it gives a true reading.
