Sestrel compasses are known for their durability and traditional design. Widely used on classic vessels, they offer excellent accuracy and mechanical stability. In India, Sestrel compasses are distributed through marine suppliers catering to commercial and heritage ship markets. Many older vessels still use Sestrel compasses, requiring periodic maintenance and deviation correction. Replacement parts are available […]

A gyro compass and a magnetic compass are both used in marine navigation, but they operate on different principles. The magnetic compass points to magnetic north using Earth’s field, while the gyro compass points to true north based on Earth’s rotation. Most ships use both as complementary systems. The magnetic compass serves as a backup […]
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. […]
Compass correction in India is a technical process performed to eliminate deviation caused by a ship’s magnetic influences. Trained compass adjusters conduct the correction by swinging the vessel and adjusting corrector magnets or compensators. This process is essential to ensure navigational accuracy. Indian marine authorities mandate compass correction as part of safety compliance for seagoing […]
