Clinometer - for measuring the angle of elevation

An excellent value-for-money sighting Clinometer for use by pupils from KS2 through to A Level.

This robust, all-plastic instrument is a clever combination of a sighting device and a plumb-bob in an easy-to-use construction. The user simply sights along the top of the instrument to the top of a building or, more usually, a mark on a ranging pole. The trigger is pulled, the weighted disc rotates under gravity and the trigger is released to lock the disc, allowing the slope angle to be read.
