LILLEY & GILLIE FW9900 Replacement Compass, ‘SR4’, Reflector

SR4 Class A Compass Benefits

The design of the SR4 magnetic compass revolutionised the way the magnetic compass was produced with the body created out of a polycarbonate compound which has two main benefits.

First, it does not have the leaking problems that traditional brass compasses suffer. Any leak in a magnetic compass can cause air bubbles to form on top of the compass, leading to problems in reading the heading accurately. The production methods and materials used in the John Lilley and Gillie SR4 compass completely resolve this problem.

Secondly, almost all of the unit is transparent, which allows more light to reach the compass card improving visibility.

Since the introduction of the SR4 compass in 2010, John Lilley and Gillie have sold several thousand units to satisfied customers all over the world with no warranty returns at all, proving the high quality of the workmanship and design.

The SR4 compass is fully compatible with the John Lilley and Gillie binnacle systems. Our binnacles are designed to allow full correction of the compass and are all approved for all vessels.
