It is much easier to use a protractor clinometers with two people. One person can sight the object through the straw while the other can note the position of the string.

A homemade clinometer is not usually used for highly precise work, such as surveying. For those tasks, use an electronic clinometer.

If the ground at the base of the object you are sighting is on a different level than the ground you are standing on, you may not get an accurate result. Try to measure or estimate the difference in heights to add or subtract to your result.
