What are the different scales used for on Clinometers?
1. The 66 foot scale (Brunton) is the same a Topographic scale (Suunto). This scale is going to give a direct reading of a height of the object being measured. By walking 66 feet (which is 1chain) from the base of the tree the scale will give a direct reading in feet of the height of the object. Metric versions are basically the same, but rely on meters not chain lengths. 2. The Percent scale can be used to get the percent grade of a slope or to figure heights as well. This scale allows you to be any distance from the tree and still calculate the tree height. For example if you read to the top of the tree at 72% and at the bottom to -6% and you are 100 ft from the base of the tree, the height would be (.72- (-.06)*100= 78 feet tall. 3. The Degree scale simply gives the angle in degrees away from being level. This is very useful in geology when determining the strike and dip of land forms. It also greatly aids in maneuvering in a submarine, but I rarely speak to naval admirals about thi
