Object Detail

This instrument was designed to simulate the effect of magnetic forces on a compass on board an iron ship. The central compass is set in a pivoting, boat-shaped board. Sliding magnetic guides are arranged around it on radial grooves. These can be moved to alter the magnetic field acting on the compass. Made by Kelvin & Hughes Ltd of Glasgow and London, this Bealls Marine Deviascope was used as a teaching aid at the principles at Leith Nautical College. It was notoriously difficult to master. It was presented to Trinity House when the college closed in 1987.
