Certified compass adjusters in India are trained to calibrate and correct magnetic compasses on ships. Using transit bearings or celestial methods, they prepare deviation charts and adjust corrector magnets. These technicians are DG Shipping-approved and work at major Indian ports.

Calibrating a ship’s magnetic compass involves identifying deviation by comparing compass bearings with known true headings, usually through a compass swing or transit bearing method. Adjustments are made using corrector magnets. The process must be done by a certified adjuster and documented with a deviation card.
Compass alignment service ensures that the compass is properly oriented along the vessel’s centerline and magnetic meridian. Misalignment can result in significant navigational errors. Indian marine technicians perform alignment during installation or post-repair. Proper alignment supports accurate autopilot inputs and navigation repeaters.
