RANGEFINDER RETICLE
7 x 50 has a built-in step rangefinder with a mils
scale for distance, angle and height detection.
DISTANCE
If the height of a
If the height of a
viewed object is
known, use the
following equation
substituting height
of object for vari-
able H:
L = H/MILS x 1000
L = H/MILS x 1000
ANGLE
To calculate the
To calculate the
included angle of a viewed object, use the fol-
lowing formula:
x° = 0.06 x MILS
x° = 0.06 x MILS
HEIGHT
If the distance to a viewed object is known, use
If the distance to a viewed object is known, use
the following equation substituting distance to
object for variable L:
H = L x MILS/1000
H = L x MILS/1000
2M TARGET BASED SCALE
A 2m target fits between the numbered base-
A 2m target fits between the numbered base-
line and the main horizontal line. If the 2m
target fits between the 4 and the right hori-
zontal post of the main line the target is 400 m
away. If the same target fits between the 7 and
the right post of main line the arget is 700 m
away.

4. Binoculars are precision instruments -
handle them with care. Do not drop, shake,
bump or rattle your binocular. Its precision
optics can become misaligned (out of collima-
tion) as a result of rough treatment, which can
render the instrument virtually unusable.
Collimation problems usually require repair

1. Before attempting to clean any of the lenses,
carefully remove all grit, sand, dirt, dust, or
other substances which may scratch the sur-
face of the optics. Avoid touching lens surfaces
with fingers or coarse materials. Use a soft lens
brush, lens cleaning tissue, a lint-free cotton
cloth, a clean cotton swab, or “canned” air.
2. For materials that remain on the lenses, use
2. For materials that remain on the lenses, use
a liquid substance designed to remove grease
(e.g., commercial lens cleaner, household
window cleaner or rubbing alcohol).
CAUTION: Do not apply liquid directly onto a
CAUTION: Do not apply liquid directly onto a
lens, which may result in the liquid seeping into
the barrel of the binocular. Apply the solution
onto a cloth or swab, and use the cloth or swab
to remove the foreign substance with circular
motions. Take care as to not rub away antire-
flectant lens coatings. Use a light touch.
If a 2m target fits
between these two
lines then the target
is 400m away.
If a 2m target fits
between these two
lines then the target is
700m away.
