Ranging by eye consider 2 pints X and Y which are inter-visible to each other. In this method ranging rod is fixed at station X and Y, which is in line with XY.

On the other side, Line ranger is a light and easy to use instrument which can be used for ranging. It consists of 2 plane mirrors or 2 right-angled isosceles prism places one above the another. Two ranging rods are fixed at inter-visible points.
