If it is a Suunto inclinometer
When you look thru the eye piece use the number on the left for elevation.

Thailog said:Trying to figure out my elevation with a clinometer but apparently I'm clueless. On the side it reads 80 but when I look through the sight it says 40? Which number do I use ?
Some clinometers are marked with percentage of grade, which is a trigonometric term of the opposite (the altitude divided by base or the distance from the sighting position to the object). It's been a long time since I've studied trigonometry, buy I believe that this is the tangent.
The percentage of grade is usually about twice that of the actual angle, with 100% being at exactly 45 degrees.
