General information
DOCTER® classic rifle scopes 6×42 and 8×56
The DOCTER® classic rifle scopes meet a hunter’s high requirements due to their
performance and design. Their sturdy execution, high optical performance and attractive
finish will soon make your rifle scope indispensable to you for stalking or the raised hide even
under extreme weather conditions.
Due to their uniform appearance and technical accessories, the standardized models offer
the following conception:
• light metal tubes with or without mounting rails
• vertical and lateral adjustment of graticule and centred graticule / vertical-lateral click
stop adjustment
• eye defect compensation
• excellent recoil-proofness
• waterproof and dustproof
• fixed magnification
Mounting
Two different basic designs of all our rifle scopes allow diverse types of mounting on your
rifle. The rifle scopes with prism-rail (1) are suitable for the traditional hook mount. Rifle
scopes without rail are suitable for slip on-, hinge- or swivel mountings where the rifle scope
is retained by clamping rings.
It will be most expedient to have your gunsmith procure and/or carry out the mounting that
suits your particular needs.
Zeroing / Adjustment of graticule
Vertical and lateral adjustment
The optical system of the rifle scopes is ex factory aligned to a distance of 100 m without
parallax. The rifle scope is mounted on the rifle and in general tested by your gunsmith by
shooting at a mark at a distance of 100 m. Moreover, our rifle scopes give the experienced
marksman the possibility of correcting the hit point position according to the respective
hunting conditions or kind of ammunition by means of their double adjustment of the graticule
(vertical (3) and lateral (4) adjustment).
To adjust the graticule, the two protecting caps (5) are unscrewed from the domes of the
graticule adjustment. When turning the handle elements underneath (6), the hit point position
is changed vertically on the upper dome (3) and laterally on the right-hand dome (4).
Vertical adjustment (H)
By turning the handle element in the direction of the arrow, the hit point position is shifted
vertically.
Lateral adjustment (R)
By turning the handle element in the direction of the arrow, the hit point position is shifted to
the right.
The defined notches of the click-stop adjustment as well as the graduated disks for retrieving
the zero point make an accurately reproducible correction of the hit point position possible.
One notch corresponds to a shift of the hit point in the target of 1 cm on a distance of 100 m.
The end of the adjustment range can be sensed by stoppers. Please note that the graticule
remains in the centre of the image and the adjustments effect a displacement of the image
detail. The graticule adjustment is sturdy and recoil-proof. In order to avoid an accidental
adjustment of the graticule and to guarantee water-proofness, the protecting caps must
always be screwed onto both domes again. In doing so you must always pay attention to the
exact position of the seal rings (7).
The special design of the reversal system allows for optical compensation for graticule
displacement in the telescopic image (centred graticule).
The graticule thus always appears in the centre of the field of view, even after subsequent
correction of the hit point position.

Attention:
To provide for a fast retrieval of the graticule’s zero position when using different ammunition
or fillings, the graduated disk (10) can be turned such after loosening the cross-drive screw
(9) that both index marks (11) face each other.
The adjustment range for correcting the hit point is sufficiently dimensioned. Should, however
the graduation not suffice, we recommend you have your rifle with the rifle scope checked by
your gunsmith.
Setting the visual acuity
The visual acuity is adjusted by turning the rear eyepiece focussing knurl (2). A marksman’s
possible eye defect is then compensated when graticule and target image stand out sharply.
Eye defect compensation of ±2.5 dioptres is possible.
Estimating distances
The free space between the transverse bars of the graticules 1, 4, 5, 7 and 9 corresponds to
a width of 70cm on a target distance of 100 m, approximately the length of a roebuck. You
can therefore estimate distances by means of the graticule.
Option: Rifle scopes with illuminated graticule
All control and functional elements of the graticule illumination system except the graticule
itself are placed in a third dome on the centre tube of the rifle scope, similar to the vertical
and lateral adjustment. The power supply is provided by a lithium battery CR2032. Using the
rotary controller (12) the graticule illumination system is turned on or off and the luminous
intensity can be adjusted according to the brightness outdoors and to the individual
requirements of the marksman. The graticule illumination system is turned off when the point
marking (14) on the rotary controller faces the one on the centre tube (13).
To replace the lithium battery, the cover of the rotary controller has to be unscrewed by
turning it to the left. The lithium battery situated under the cover (15) can now be replaced.
Then the cover can be screwed together again with the rotary controller (12).
Accessories
To protect the outer parts of the instrument, interconnected protecting caps are delivered.
As a protection against lateral light, a telescopic rubber shade can be delivered on request,
which simultaneously guarantees the correct eye distance to the eyepiece and absorbs a
possible recoil.
Maintenance
When carefully operated, DOCTER® rifle scopes have a virtually unlimited life.
Before cleaning, the outer lens surfaces should be freed from dust (by means of a lens brush
or air bulb). This way, dirt particles and dust are prevented from being rubbed into the
blooming coat and damaging it. Abstain from using chemical solvents for cleaning the outer
lens surfaces!
In case of possible damage causing malfunction, the instrument must be sent to an
authorized repair shop.
