All magnetic compasses are vulnerable to magnetic interference which will produce errors called deviation. It is the owner/operator and/or helmsman s responsibility to make sure the compass is properly installed and compensated. Compensation is the act of correcting for deviation. Magnets (speakers microphones etc. ) ferrous metals (steel iron etc. ) and current-carrying devices are common causes of deviation. It is important to understand that magnetic compasses point toward the magnetic north. There is a difference between magnetic north and true north and that difference is called variation. Variation differs depending on your geographical location and can be determined by referring to a local chart.
