SR4 Class A Compass
The SR4 Class A Compass from John Lilley & Gillie is a sophisticated marine navigation tool that solves many of the traditional issues associated with brass compasses. The SR4 is constructed with a durable polycarbonate based material, and since it is not brass, you will not have to worry about leakage at the joints - as brass compasses often do. It also prevents air bubbles forming in the liquid filled bowl, which is an advantage for readability/ and allows for full visibility. The nature of the nearly transparent construction allows good light entry. The SR4 Compass has full Class A compliance and is in use on civilian, naval, coast guard ships globally. It is compliant with the European Marine Equipment Directive, Chinese Classification Society, and numerous other marine authorities.
