The sensing element is free from magnets, rotating cards and jewelled bearings. It simply consists of a double gimbal, one primary coil, two secondary coils, lead and oil damping fluid. The housing permits tilt up to 30º. Features include a pressure stable and waterproof construction designed for easy maintenance. Small dimensions, light weight, good linearity, high accuracy and good long time stability free from drift.
On smaller vessels, fluxgate compasses have become very popular, but they require a reliable electrical source although they do have digital capabilities.
