Dioptre adjustment in the BLASER
1-7x28 iC
To ensure optimum target acquisition with
both eyes open, set the dioptre adjustment
for the BLASER 1-7x28 iC with 1x magni-
cation. To do this, look at a distant target (>
50 m) through the riescope. The other eye
(i.e. the left eye of right-hand shooters and
vice versa) also remains open, so that both
eyes look at the target. Now turn the dioptre
adjustment anticlockwise and then turn it
back in, until both images are equal in size
and both appear equally focussed. If the cor-
rect setting has been found, an undisturbed
binocular image with a focussed reticle will
result.
Parallax adjustment – focussing the
target image
The parallax adjustment is used in rie-
scopes with high magnication to set the
focus for dierent distances and at the same
time prevents possible point of impact shift
due to parallax (shift of the reticle on the tar-
get when the eye is not centered in the exit
pupil). Models 2.8-20x50 iC and 4-20x58iC
are equipped with a parallax adjustment
dial. This, together with the illumination
dial, is located on the right of the main tube
(Fig. 3). The parallax adjustment dial locks
automatically in the 100m position. In this
locked position the riescope behaves like a
riescope with xed parallax setting adjust-
ed to 100m. The markings on the parallax
adjustment (II and III for 200m and 300m)
are orientation aids; precise adjustment
should be made using the best image
sharpness at maximum magnication at the
respective shooting distance.
The adjustment is made by pulling out and
turning the setting ring within the range
from 50 m to innity. Starting from the
100m latch point, move to the 50m setting
by turning clockwise; the settings for further
distances up to innity are reached by turn-
ing anticlockwise.
The BLASER 1-7x28 iC does not require
parallax adjustment due to its maximum 7x
magnication. It is adjusted parallax-free at
100m.
