Scale
As long as the two halves of the drive are
coupled together, the binoculars are perma-
nently adjusted to your eyesight, irrespective
of the focusing distance to an object. You
need to make the adjustment only once. If
other people use your binoculars, they may
have to alter the setting. Simply note your per-
sonal setting on the scale; when someone else
has used them, you can reset the binoculars in
a matter of seconds. The distance between two
divisions on the scale represents a difference
of 1 diopter in the strength of correction being
applied to the left and right eye. If the dot on
the focusing thumbwheel lines up with the
arrow on the armouring, the binoculars are
focused to infinity (∞) (at 0 diopter eyesight
correction).
