You are obviously having some difficulty figuring out this clinometer stuff. It is a bit technical, and you need an understanding of angles, geometry, maybe even trigonometry, etc. to really figure this out.

The clinometer seems to have been invented by William B. Melick.

There are different kinds of clinometers and they have different uses. They are used by construction workers to measure grade angles, by forestry workers to measure the height of trees, and by movie directors to measure the height of the sun. They are also used by satellite antenna installers to find satellites.

To use the clinometer, you look through an eyepiece with one eye to see the angle measuring scale and a horizontal line. With the other eye, you sight on the object you want to measure, like the crest of a waterfall. When the horizontal line is aligned with with the crest of the waterfall, you simply read the scale to find the angle in degrees.

When you use a clinometer, try to sight on a distinct object like a small sapling, stick, or rock at the crest of the waterfall or the edge of the plunge pool. Take your sighting three times and then average the results.

One of these sites explains how to make a homemade clinometer and has pictures of how to use it, so it might help you. Best of luck with it.

Here is some information:

Captain William Abney created clinometer.

The clinometer is an optical device for measuring elevation angles above horizontal. The most common instruments of this type currently used are compass-clinometers from Suunto or Silva. Compass clinometers are fundamentally just magnetic compasses held with their plane vertical so that a plummet or its equivalent can point to the elevation of the sight line. A better clinometer (I believe) is the Abney hand spirit level or clinometer, where the object sighted and the level bubble can be seen simultaneously, so that the index can be set accurately. An Abney clinometer is shown in the photograph. A spirit level is so-called because it contains alcohol in a tube of large radius, in which the bubble moves to the highest point. Spirit levels are used for accurate surveying, although automatic levels that go back to the principle of the plummet are now frequently found, and are easy to use.

The Abney clinometer has a sighting tube with an angle scale reading from -90° to +90°, and a spirit level with a Vernier index that can be moved along the scale while the user looks through the sighting tube. A small mirror and lens makes the level bubble visible in the field of view. When the object is aligned with the crosshair in the sighting tube, the spirit level is rotated so that the bubble is bisected by the crosshair, as illustrated in the diagram. Then, the elevation of the line of sight can be read off on the scale. The Vernier can be read to 10', but it requires a magnifier to do this. The clinometer can read easily and accurately angles of elevation that would be very difficult to measure in any other simple and inexpensive way.

Hope I helped!

A clinometer also known as an inclinometer is an instrument for measuring angles of slope (or tilt), elevation or inclination of an object with respect to gravity. Also known as a tilt meter, tilt indicator, slope meter, slope gauge, gradient meter, gradiometer, level gauge, level meter, pitch & roll indicator.

Estimating the height of a building, tree, or other feature using a vertical angle and a distance (determined by taping or pacing).


A fairly common use of a clinometer is to measure the height of trees, which is easily done. A point should be marked with a stake as far from the centre of the trunk of the tree as its estimated height, so that the elevation angle is about 45°, which gives the best "geometry." This distance D is measured with a tape. The observer then stands over the stake and sights the top of the tree, finding its elevation angle θ. The height H of the tree is then H = D tan θ + HI, where HI, the height of instrument, is the height of the observer's eye.

Some of the earliest examples of the rotating pointer are found in inclinometers manufactured by Rufus Porter, the inventor, artist and Scientific American founder, who is sometimes referred to as the American da Vinci.
