Warnings
* Use caution when walking with the clinometer to your eye as you could poke your eye if you fall.
* If you require a very high degree of precision, you should probably 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, or if the object you are sighting is leaning, you will not get an accurate measurement without adjusting your calculations.
