a) b)
Using the reticles for rangefinding
The integrated graticule serves for determination of distance of distant ob-
jects.
If the height or length of the target object is approximately known, the dis-
tance can be determined using the following formulas:
Height of the target object ( m ) x 100
Distance ( in m ) =
Elevation of the target object ( ° )
Length of the target object (m) x 100
=
Azimuth of the target object(°)
Elevation = vertical angle
Azimuth = horizontal angle
Example: The object height of the pictured lighthouse is 60 m. For the height
of the lighthouse, the value 6.0 can be read on the graticule.
≈ 1,000 m
60 m x 100
Distance ( m ) =
Result:
6.0
