with quick glances while turning the eyepiece focus ring (8) clockwise or counter
clockwise until the image of the reticle pattern appears clear and sharp.
Note: Focusing should be done at maximum power to ensure that the image will
remain sharp within the entire power range.

Elevation and Windage Adjustment

ZEISS TERRA 3X riflescopes feature audible click elevation and windage
adjustments. One click corresponds to ¼ MOA (Minute of Angle). In other terms,
one click corresponds to ¼ inch at 100 yards, ½ inch at 200 yards, ¾ inch at 300
yards and so on. In metric adjustment, one MOA (four clicks) moves the point
of impact by 29mm at 100 meters. In order to make adjustments, you must first
unscrew the protective windage and elevation caps.
ELEVATION:
Unscrew protective cap for elevation (5).
If the rifle shoots low, turn elevation dial (4) counter clockwise to move the point
of impact up (“UP” direction).
If the rifle shoots high, turn elevation dial (4) clockwise to move the point of
impact down.
WINDAGE:
Unscrew protective cap for windage (6).
If the rifle shoots too far left, turn windage dial (7) counter clockwise to move the
point of impact toward the right (“R” direction).
If the rifle shoots too far right, turn windage dial (7) clockwise to move the point
of impact toward the left.

3

Magnification

Change the power by turning the magnification ring (1) on the eyepiece counter
clockwise (to increase power) or clockwise (to decrease power). Align the index
of the magnification ring with the desired magnification setting on the eyepiece.
Use your riflescope on a lower power setting (resulting in a wider field of view) to
make a quick shot at close distance. Increase the magnification level for precision
long-range shots.

Reticle

Your riflescope is equipped with a reticle pattern of your choice. The reticles of all
ZEISS TERRA 3X riflescopes are located in the second image plane. This means,
that only the target image is magnified and changes when the power is changed

- the recticle size does not change. Therefore, range estimations with second
image plane reticles should always be done at consistent power. For ZEISS TERRA
3X riflescopes with RZ ballistic reticle, please refer to page 7.

Riflescope installation and use

Centering the Reticle

For the optimum adjustment range, the reticle was factory pre-set at the optical
center of your riflescope. We recommend that you verify the center of the optical
axis before mounting.

4

Mounting

ZEISS TERRA 3X riflescopes require 1-inch rings. Only use high quality rings and
bases recommended for your rifle and follow ring manufacturer’s instructions
for mounting. The riflescope should be mounted as low as possible, without
touching anything except the mounting rings. Before tightening the rings, adjust
for maximum eye-relief with full field of view to avoid injury from recoil. Also be
certain your scope is mounted level on the 180° axis.

Bore Sighting

Bore sighting saves time and ammunition and is recommended to achieve proper
alignment of the riflescope with the rifle’s bore. You can either use a Bore Sighter
for this process, or simply remove the bolt and sight through the barrel at a 25
yard target. With the bulls-eye centered in the bore (Fig. 1), make windage
and elevation adjustments to move the crosshairs to the bulls-eye on the target

(Fig. 2). Be careful not to move rifle during windage and elevation adjustments.

Zeroing

Final sighting-in of your rifle should be done using the exact ammunition you
expect to hunt or shoot with.
a. Carefully fire a three-shot group
b. Use the center of that group as a reference point for adjustments to windage

and elevation

5

c. Example (Fig. 3): the center of the group on the target is two inches low

and three inches right. If you are sighting-in at 100 yards, you should make a
2-MOA adjustment up, and a 3-MOA adjustment left. 1 click corresponds to ¼
MOA (Minute of Angle).

Care and maintenance

To clean, blow off any dust or carefully wipe off larger dirt particle with a soft
brush. Fingerprints, and other more stubborn stains should be removed with
water or a premium optical lens cleaner, and a soft microfiber cloth. Avoid storing
the scope in places with excessive heat. We recommend to store your riflescope
in a dry place with good ventilation.

Introduction

Congratulations on the purchase of your new ZEISS riflescope with RZ Reticles
ballistic.

RZ Reticles combined with the superior optics and performance that ZEISS is
known for will provide you with the best riflescope to take afield or to the range.

The key to this system is the Optimal Power Setting as determined by the ZEISS
Ballistic Calculator. This will provide you with the ideal power setting in order to
provide accurate shot placement while using the holdover bars.

Most other ballistic reticle systems rely on the scope being set to its maximum
power setting and corresponding potential loss of accuracy or intuitive placement
of the bars. The ZEISS Ballistic Calculator will provide you with the Optimal Power
Setting to match the bars of the RZ reticle to the specific drop of the ammunition
you are using.

Note: Optimum Power Setting will change with variables like elevation,
bullet weight, velocity, BC, etc. You only need to set the magnification
to the Optimum Power Setting when using the reticle holdover bars.

9

Classification

Each RZ Reticle is designed to match a category or type of ammunition. The
reticles are not limited to these calibers or uses, but the correct caliber class
provides the best performance and reticle selection.

1. If you do not have internet access, please call ZEISS Customer Service

to assist you in determining the OPTIMAL POWER SETTING for your scope

(1-800-441-3005).

2. If you do have internet access log on to www.zeiss.com/us/sports-optics,

access the ZEISS Ballistic Calculator and follow the online step-by-step
instructions to determine the OPTIMAL POWER SETTING for your scope.

11

Here you will:
� Select your factory load or bullet (if handloading).
� Change any atmospheric conditions that will affect ballistics, i.e. temperature

or altitude.
� Change any ballistics information related to handloads, i.e. muzzle velocity.
� Determine the Optimal Power setting for your scope based on the parameters

you have selected.

3. Zero your rifle at 200 yards using the center crosshair. If access to a 200 yard

range is not available, then shoot at 100 yards and follow the ZEISS Ballistic
Calculator’s or manufacturer’s recommended height of shot placement over
the target bulls-eye for a 200 yard zero (example 1.5 inches high at 100 yards).

4. Once you have completed your sighting in process and are ready for shooting,

remember, you may set your scope to any power setting you wish to shoot at

targets from 0 to 300 yards. The point of impact shift between these distances

is typically insignificant on big game. For example, if you are hunting in areas

with dense cover or reduced visibility, you may not have a need for the holdover

lines and simply use the center crosshair.

5. To fine tune your point of aim:
� If shots are slightly high, turn the magnification ring up in very small (<1/4)

power increments.

� If shots are slightly low, turn the magnification ring down in very small (<1/4)

power increments until correct zero is achieved.

12

� Note: At extended ranges altitude and temperature affect Point of Impact

(Example: 0 to 10,000 ft. = POI shift beyond 500 yards of 8“, or more.)
For a complete list of all factory calibers and handloading bullet types please
visit the calculator on the ZEISS web site at www.zeiss.com/us/sports-optics.

Holdover / Shot Placement

RZ Reticles can be used with numerous caliber and load combinations. Holdover
values in the reticle correspond to those exact distances in yards. Once your rifle
is zeroed at 200 yards on the center crosshair and with the magnification ring
set to the recommended power setting (obtained on the the ZEISS website) the
reticle will now be ready for long range shooting.

XB75 reticle

Introduction

Your TERRA 3X with XB75 reticle is a high performance optical device designed
to provide years of reliability and service. The XB75 patented reticle allows users
to determine aiming points from 20–75 yards in 2.5 yard increments (crosshairs
represent whole yards and dots represent half yards, top and bottom of each
crosshair represents 2.5 yard increments) when shooting crossbows with speeds
from 275 fps–425 fps.

Parallax

The ZEISS XB75 Reticle riflescope is factory set to be parallax free at 30yards.

Zeroing with XB75 Reticle

Choose a place to shoot your crossbow with a safe backstop and ensure that no
one can step unseen into or in front of the shooting lane. To start the zeroing
process, place a target in front of the backstop at a measured distance of 10
yards. Now take your first shot at the center of the target. If an adjustment is
required, remove the dust covers from the windage and elevation turrets of the
scope. Now make your adjustment to the turret to bring the point of impact (POI)
closer to your point of aim (POA).
For example: If the arrow impact is lower than your aiming point; rotate the
elevation turret counter clockwise to raise the point of impact. A high impact
point requires a clockwise adjustment. Both turrets will move the (POA) a 1/4
minute of angle per click – this is equal to a 1/4 inch at 100 yards. (4 clicks to
move the impact 1” at 100 yards). Since you are sighting in at 10 yards and 20
yards, please remember that you will need 20 clicks to move the impact 1” at 20
yards, and 40 clicks to move the point of impact 1” at 10 yards. After achieving

16

an approximate zero at 10 yards, move to a distance of 20 yards and continue
adjusting the turrets until the top crosshair of the reticle and the point of impact
are the same at this distance,. When you are satisfied with the 20 yard zero,
reattach the turret caps.

Calibrating your scope to the crossbow

The ocular ring has engravings for speed and magnification. Adjusting the
speed selector also adjusts the magnification. Start by setting the XB75 scope
to the chronographed speed of your crossbow. If you do not have an actual
chronographed speed, use manufacturers advertised speed of your crossbow. Move
to a measured 30 yards from the target. Using the 30 yard marker in the scope, (the
second crosshair down) shoot the crossbow at the target. If the arrow impacts the
target high of your aiming point, turn the speed selector to a higher speed position
and the next arrow shot will impact the target lower. If the arrow impacts the target
lower than your aiming point, turn the speed selector to lower speed position and
the next arrow shot will impact the target higher. Once the 30 yard crosshair is
sighted in, the scope is now calibrated to your crossbow and all of the other aiming
points will be correct. At this time, the speed/magnification selector will need to
remain in this position (make a note of the position) to keep the scope and the
crossbow calibrated to each other. Crossbows with speeds over 425 fps and using
a lighter arrow combination may require a main crosswire sight-in point of 30 yards
instead of the normal 20 yards. This will require calibrating the scope at 40 yards to
compensate for the flat trajectory of the crossbow bolt.

For additional fine tuning instructions, please visit www.zeiss.com/sports and
view the updated on-line user manual operating instructions for the TERRA XB75
Crossbow Scope.
