The impact on the compass, called \"deviation\", can originate from many different sources: metallic masses, loudspeakers, engines, electronic instruments… If deviation ranks between 7 and 20°, your compass should indeed be compensated. Our compasses are supplied with built-in compensation or can be further equipped with an optional compensation cell. They are designed to be user compensated. 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. Use a second compass as the reference; a hand-bearing compass is often the most convenient, provided it is interference-free. The North-South screw corrects North-South heading; the East\/West screw corrects the East-West heading. • Run the boat along the Northerly course selected as per your hand-bearing 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.\u003c\/p\u003e","brand":"Plastimo","offers":[{"title":"Default Title","offer_id":56393282027906,"sku":"17673","price":28.28,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/4799\/3639\/files\/compensation_17673.jpg?v=1771501741","url":"https:\/\/proteusmarinestore.com\/products\/compensation-for-cont-100-130-mini-b","provider":"PROTEUS MARINE STORE","version":"1.0","type":"link"}
