Reflector Binnacle Compass is installed upon the flying bridge deck and can be seen in the wheelhouse for both standard compass and steering purposes. The binnacle has an optical equipment by which graduation of the card can be reflected on the lower part of the inner pipe. This avoids the bad effect due to other magnetic substances also saves the space in the steering room. By increasing the magnification on the reflected graduation using the built-in room lens, reflector compass surpass the conventional compass.
