About This Product
An optical square is a small hand-held surveying instrument that lets the user set out a right angle on the ground without a theodolite. Pentaprisms bend the line of sight through a right angle, so the user can sight along one line and see a marker pole on the line at a right angle to it. It is used to mark out plots and fields and to set offsets from a line measured with a Measuring Tape. In surveying lessons, students practise setting out a rectangle and checking its corners. School Lab Equipment India supplies the Optical Square across India and can export it to Colombia, South Sudan, Rwanda, Vanuatu and Argentina.
