Initially, a Bushnell 500 Yardage Pro laser rangefinder was used in conjunction with a Suunto clinometer to estimate tree heights in all regions.

The clinometer is a hand-held device that measures angles and, when used with a calculator, can determine the height of a tree.
33.
From each station the position of a point on the surface of the crown can be mapped using a compass, laser rangefinder, and clinometer.
34.
A clinometer, combined with a graduated elevation dial fitted to the tripod would be employed to set the gun to the correct elevation . . . "'
35.
A single height measurement takes only a matter of a few minutes using separate laser rangefinder and clinometer or less when using instruments with a built in electronic clinometer.

Elliott Brothers of London registered an " improved clinometer and spirit level combined " in December 1870 based on " the old form as originally designed by Lieutenant Abney ."
38.
The rocking bar and telescope were retained for direct fire, as was the range scale on the right in spite of a clinometer being part of the Dial Sight mount.
39.
Using the rangefinder and clinometer, only four numbers are needed to complete the tree height calculation, and no tape is necessary, nor is direct contact with the tree.
40.
A combination of a monocular w / reticle, laser rangefinder, and a clinometer can be used to do go from simple diameters to a full measure of trunk volume.
