ENGLISH
Object length (m) =
Distance of the object (m) x Azimuth
100
Example:
The distance to the front sailing ship is 1200 m. The sailing ship is located on
the graticule between the horizontal scale values 0 and 2. Thus, the horizon-
tal visual angle is 2 graduation lines / 20 lines.
Result:
Ship length =
1,200 m x 2
100
= 24 m
MAINTENANCE AND CARE
The prism binoculars require no special care, they are virtually mainte-
nance-free. Optic external surfaces must be cleaned with a fine brush or a
soft cloth if necessary. Coarse dirt particle should be rinsed off or blown off
before wiping. An excessive rubbing when brushing the optical parts can
destroy the anti-reflection coating. No chemical solvents should be used and
the binoculars should be stored dry!
