Pocket Compass with Ring, Ø40 mm

A pocket compass housed in a nickel-plated brass case 40 mm in diameter, with a 360° scale graduated in 5° steps for easy reading and a needle on a jewelled (stone) bearing for precise movement. A small ring lets you attach it to a cord or carabiner for convenient carrying in the field. In geography, biology and science lessons it is well suited to training pupils' orientation and navigation skills, letting them practise finding the cardinal points and reading bearings.
