The interpupillary distance, or the distance
between the pupils, varies from person to
person. The binocular must be correctly aligned
(adjusted) to the distance between your pupils
to achieve a single, clear image. To adjust this
distance, lift the binocular up to your eyes (using
both hands) and look through them at an object
in the distance. Move the two barrels (halves)
of the binocular closer together or further
apart until you see a single, clear image (Fig. 2).
Check that the interpupillary distance is set
correctly every time you use your binocular.

Models 71420, 71424, and 71426
To ensure a crisp, sharp image the focusing
system of the binocular must be set to
compensate for any differences in your
eyesight. This is achieved by setting the
diopter (located on the right eyepiece) before
use. To set the binocular to your eyesight
follow the instructions below.
1. View an object in the distance through
the binocular.
2. Cover the right objective lens with your hand
or the objective lens cap.
3. Rotate the focus wheel until the image
viewed with your left eye is clear and sharp.
4. Cover the left objective lens with your hand
or objective lens cap.
5. Viewing the same object, adjust the diopter
ring until the image viewed with your right
eye is clear and sharp.
6. Your binocular is now adjusted to your eyes
and focusing on any object can now be
achieved by simply turning the focus wheel.

ENGLISH I5
Model 71422
The Cavalry 7x50 utilizes an individual focus
system which requires you to focus each
eyepiece to ensure a crisp, sharp image. This
is achieved by setting the diopter (located on
each eyepiece) before use. Once the binocular
is adjusted to your eyesight at a distance of
approximately 100 yards, the binocular will be in
focus without additional adjustment to an infinite
distance (for distances closer than 100 yards
readjustment may be necessary). To set the
binocular to your eyesight follow the instructions
below.
1. View an object at a distance of 100 yards
or more through the binocular.
2. Cover the right objective lens with your hand
or the objective lens cap.
3. Rotate the left eyepiece until the image
viewed with your left eye is clear and sharp.
4. Cover the left objective lens with your hand
or objective lens cap.
5. Viewing the same object, rotate the right
eyepiece until the image viewed with your
right eye is clear and sharp.
6. Your binocular is now adjusted to your eyes
and refocusing is not necessary for objects
at 100 yards or more. Adjustment may be
needed for distances closer than 100 yards.

eyecup adjustMent
The Cavalry models 71420 and 71424 feature
twist-up eyecups and models 71422, 71426
and 71215 feature foldable rubber eyecups to
accommodate both eyeglass and non-eyeglass
wearers. If you do not wear eyeglasses, leave
the rubber eyecups in the up position or twist
the eyecups counterclockwise until they reach
the up position. If you wear eyeglasses, make
sure that the eyecups are in the down position
to obtain the maximum field of view. The twist-
up eyecups can be set at positions between
fully up and down which may suit some users
better. When done observing, make sure the
rubber eyecups are in the up position for storage.
Model 71215
The focus of the Cavalry 8x42 monocular
is adjusted by simply turning the focus ring
located in front of the eyepiece.
Tip: Eyeglasses worn for nearsightedness should be worn when using a
binocular/monocular as you may not be able to obtain focus at infinity
without them.

tripod adaptability
The Cavalry binoculars feature built-in threads
that allow the binocular to be attached to a
tripod using a binocular tripod adapter. These
threads can be accessed by unscrewing the
logo plate found on the front of the hinge (Fig. 7).
To attach the binocular to a tripod, thread the
adapter into the binocular and attach the other
end of the adapter to a photographic tripod.
Mounting the binocular on a tripod allows for
added stability and comfort during prolonged
viewing.
WaterprooF / FogprooF
The Cavalry Series is waterproof and filled with dry nitrogen gas to prevent the housing from
fogging internally.

using the reticle
calculating distance
Cavalry models 71420, 71422 and 71215
have an integrated reticle that can be used to
estimate size and distance. The reticle is divided
into 10mil increments with 5mil marks between
each 10mil increment. Each 10mil increment
is indicated using single digit numbers (1, 2,
3, etc.). For finer ranging ability the last 5mils
of the reticle are divided into 1mil and 0.5mil
increments.
Note: The reticle varies slightly from model to model but this does not
affect how distance and size are calculated.
Using the simple formulas below, you can
effectively determine the distance to the
target if its size is known.
Target Size (Yards) x 1000
Measured Mils = Range (Yards)
Fig. 8
Fig. 9

ENGLISH I9
The Calculator Dial located on the left objective
barrel can be used to determine distance quickly
and easily without using the formulas above. The
calculator is composed of a triangular indicator
marked “Angle”, a rotating ring and three number
scales. The first two scales are on the rotating
ring; the first scale is the “Angle” measured in
MILS and the second scale is the “Object Size”.
The third scale below the rotating ring is the
“Distance” reading. To use the calculator, look
through the binoculars and measure the height
of an object using the reticle. Using the same
example above, a man is seen that measures
20mils tall. Using the rotating ring, align the
triangular indicator to the number 2 (20mils) on
the Angle scale. Estimating that the man is 6
feet tall (2 yards), locate the number 2 on the
“Object Size” scale. Each number on the “Object
Size” scale will correspond to a number on the
fixed distance scale. In this example the 2 on the
distance scale is lined up with 100, so the man
measured in the binocular is 100 yards away.
For example:
You range a 6-foot tall man (2 yards) that is
20mils tall and you want to know the distance
to him.

calculating size (height and Width)
Using the simple formulas below, you can
effectively determine the size of a target if
the distance to the target is known.
For example:
You are 300 meters away from a tank that
measures 15 miles tall and 20mils wide and
you want to know the size of the tank.
Range (Yards) x Measured Mils
1000 = Target size (Yards)
Range (Meters) x Measured Mils
1000 = Target size (Meters)
300 (Meters) x 15 Mils
1000 = 4.5 Meters tall
300 (Meters) x 20 Mils
1000 = 6 Meters wide
Range (Yards) x Measured Mils
27.8 = Target size (Inches)

integrated coMpass
Models 71420, 71215
Models 71420 and 71215 have a built in
6400mil analog compass. The compass reading
is aligned with the vertical line of the reticle and
each hash mark of the compass represents 20
mils. The compass will only indicate direction
to or from an object but not relative position.
To determine position you need a map or chart
and a protractor. When an object lies north
from you, the compass will read 64 (6400mils).
The mils will increase as you look through the
binocular and scan clockwise. 16 (1600mils)
means that the object lies east from you, 32
(3200mils) is south and 48 (4800mils) is west.
To ensure precise measurements, make sure
that the object is in the middle of the reticle
and that the binocular is held horizontal and
level when reading the compass.
Note: When using the compass always keep in mind the local variation
between magnetic north (the compass reading) and true north. When
holding the binocular make sure that your finger/hand is not covering the
white button (compass window) on the top of the binocular as it allows
light to enter the binocular so the compass reading can be seen.

When the device is in GPS mode, a signal icon
designated by four vertical bars of increasing
height will appear in the upper left hand corner
of the LCD screen. While a signal is being
acquired, the icon will flash red. Once a signal
is acquired the icon will stop flashing and
turn blue. GPS mode provides latitude and
longitude coordinates as well as altitude
readings. Please see the disclaimer at the
end of this manual regarding the accuracy
of readings.

In level mode, the screen will display a large
black circle with a small stationary blue circle
in its center. A small red circle representing a
“bubble” will move as the binoculars are tilted.
When the red “bubble” aligns perfectly with the
small blue circle, the binoculars are level.
In compass mode, the screen displays a digital
compass and readings (in both degrees and
mils) for the bearing that the objective lenses
are facing. A red stationary arrow points in the
direction you are facing when looking through
the binoculars while a circle containing the
readings N/S/E/W rotates as the binocular
is moved (the red N will always point North).
The bearing that the red arrow points to is
displayed in degrees and mils on the LCD screen.
Keep in mind that the digital compass points
to true North, which is different from the analog
compass reading of the other Cavalry models.
