The calibration service consists in adjusting the direction in which the navigation arrow of the compass, points out the north and the actual direction of the north according to the magnetic field of the planet. The information acquired in the calibration allows calculating the differential error between the magnetic compass needle and the actual magnetic direction, using the detour tables, given by the professional in charge of the calibration service.
This service can be done at any time and in any type of magnetic compass, as well as it can assist in helping with the analysis of all the data and hand on equipment processes. It is an important help in long journeys and detours as an option against the loss of valuable resources.
