The two main ways to use PoleClinometer are described below.
IMPORTANT: Your pole MUST HANG FREELY from a loose grip as shown. This is your vertical reference. If your pole isn’t hanging freely, then your reading will be wrong!
From the Side (Sighting Across the Slope)
With a side view of a slope, sight across it as shown.
Look for the PoleClinometer lines that appear to match the angle of the slope.
Here the angle of the slope appears to be about half way between the angles of the lines marked “30” and “35”, so the slope angle is somewhere around 32 or 33 degrees.
From the Top (Sighting Down the Slope)
At the top of a slope, sight down it as shown.
Position yourself so your line of sight matches the angle of the slope.
Look for the PoleClinometer lines that appear least curved in your line of sight.
Here the line marked “30” is curved slightly up, while the line marked “35” is curved slightly down, to about an equal degree, so the slope angle is somewhere around 32 or 33 degrees.
Other Methods of Use + Tips & Tricks
The two techniques described above will probably be the ones you’ll use most, but there are other ways to use your PoleClinometer too. Look for descriptions of additional PoleClinometer use modes to appear on this page in the not-too-distant future, along with some general tips and tricks for getting good accurate readings.
