Deviation correction in magnetic compasses is performed to align the compass reading with true magnetic direction. Deviation occurs due to the magnetic influence of onboard equipment and ship structure. Technicians swing the ship in controlled headings and record deviations. Adjustments are made using compensating magnets or soft iron spheres in the compass binnacle. This service […]

Marine compass calibration is essential for ensuring precise heading information. Calibration adjusts the compass to reduce or eliminate deviation caused by nearby magnetic fields. This process is often done by swinging the vessel and recording compass readings on multiple headings. Certified marine technicians use this data to prepare a deviation card or adjust the compensators. […]
Magnetic compass calibration is essential for accurate navigation. Calibration involves adjusting for deviations caused by the ship’s magnetic field. This process includes swinging the compass and recording errors, followed by adjustments or creating deviation cards. Calibration must be done by trained personnel or service providers. It ensures compliance with marine safety regulations and prevents navigational […]
