The Omni-Slope LED Inclinometer from Brunton measures angles in degrees, percent grade, and 66' forestry chains for land surveying purposes. The degree scale is broken up into 1° increments, and the inclinometer is accurate to within a 1/2°. Its illuminated dial ensures that the scales can clearly be seen even in low-light conditions. The inclinometer's lightweight, aluminum housing is durable and designed for years of field use.

A precision pendulum with a 180° range gives fast, smooth, and accurate readings of height and pitch. Height can be calculated using the percentage scale and the distance between yourself and the object to be measured. As an alternative, you can simply use the 66' forestry chain scale and read out the correct height without calculating anything.
