COMPENSATION
Compasses are supplied with built-in compensation, or can be further equipped with an optional compensation. Compensating a compass consists in adjusting the position of the 2 magnets, in order to affect the horizontal component of the card by modifying the North/South and East/West deviation. The compensation procedure is a delicate operation and should ideally be carried out by a professional compass adjuster.

How to compensate a compass
Use a second compass as the reference ; a handbearing compass is often the most convenient, provided it is interference-free. The North-South screw corrects North-South heading ; the East/West screw corrects East-West heading. Run the boat along the Northerly course selected as per your handbearing compass and adjust your steering compass by turning the North and South screws either way, so that the steering compass also points North. Repeat the procedure, running the boat Easterly. Run the boat Southerly and this time, reduce the deviation by half. Run the boat Westerly and reduce the deviation by half. Note : Upon completing the compensation procedure, it is essential to draw a new deviation table.
