    The relascope, invented by Walter Bitterlich, is a multi-use instrument for forest inventory. It is primarily used to find the height of a tree, the basal area of a tree, and the diameter of a tree anywhere along the bole.

    Basal Area Factor (BAF) 5, 10, and 20 angle gauges result in PRFs of 3.89, 2.75, and 1.94 (feet inch −1) respectively. The metric equivalents of these PRFs are 0.467, 0.33, and 0.233 (m cm −1 ). When a tree is borderline, a series of measurements and calculations must be made to determine if the tree is in or out.

    Reviews of the sine method have been published by U. S. Forest researcher Dr. Don Bragg. [28] [29] He writes: "When heights were measured properly and under favorable circumstances, the results obtained by the tangent and sine methods differed only by about 2 percent. Under more challenging conditions, however, errors ranged from 8 to 42 percent.
