Marine Electronics Navigation Reflector Magnetic Compass
Marine reflector magnetic compass is a navigational instrument that is commonly used on boats and ships to determine the direction of travel. It is called a reflector compass because it uses a system of mirrors to reflect and amplify the readings of the compass. The marine reflector magnetic compass typically consists of a circular card with markings indicating the cardinal and intermediate directions. The card is mounted on a pivot or bearing that allows it to rotate freely. A magnetized needle or bar is attached to the center of the card and aligns itself with the Earth's magnetic field, indicating the direction of magnetic north. The housing or bowl of the compass is typically made of brass or other non-magnetic materials to reduce interference with the magnetic field. It is filled with a liquid, such as oil, which helps to dampen any movements of the card and needle, and provides stability and accuracy of the readings. The reflector system consists of a series of mirrors that reflect the image of the compass card onto a viewing screen or eyepiece. This makes it easier for the navigator to read and interpret the compass readings, especially in low light or poor visibility conditions. Marine reflector magnetic compasses may also be equipped with additional features, such as automatic deviation compensation, which adjusts the readings to account for any magnetic interference from the boat or ship's equipment. They may also be mounted on a gimbal or other stabilization system to keep the compass level and accurate even in rough seas.
The marine reflector magnetic compass is mounted on top of the steering room. The reflection compass not only has the same precision as the standard compass, but also has the functions as viewing window, reflector, direct guide steering. The compass box is equipped with an optical instrument through which the compass scales can be reflected above the front of the steering room. This helps to reduce shipbuilding costs, improve magnetic field efficiency and make the steering room more spacious.
