How to use a hypsometer

WebEssentially we measure the straight-line distance to the top of a tree using a laser rangefinder. Then we measure the angle to the top of the tree with a clinometer. The height above eye level is calculated using a pocket calculator to be the trigonometric sine of the clinometer reading x the distance measured to the top of the tree. WebGRS Densitometer. $220.00.
