Using the Solo R/T Reticle
The Solo R/T reticle is based on a form of angular
measurement called the milliradian (mrad for short).
These angular measurements allow a user to calculate
ranges when comparing the reticle to objects of known
dimension. The key to effective ranging using this
reticle is knowing common objects in your vicinity and
their measurements.

Ranging with mrads
Mrad measurements are very effective for ranging using
simple formulas. Knowing the size of the target or a
nearby object is essential to using these formulas.
Accurate measuring will depend on a very steady hold.
Be sure to solidly brace the arms when measuring or
use a tripod mount for maximum accuracy. Once you
have an accurate mrad reading, use one of the formulas
to calculate the distance.

Using either the vertical or horizontal mrad scale,
place the reticle on the target of known dimension and
read the number of mrads spanned. Obtain maximum
accuracy in ranging by calculating exact mrad
measurements—try to estimate mrad measurement in
1/10s if possible.

Basic Operation
Accessories
Adjusting the Image Focus
Use the main focus wheel on the
eyepiece to obtain crisp, sharp
images of objects at varying
distances. Designed for quick singlehanded operation, simply place the
thumb and forefinger on the focus
wheel and turn to move lens forward
or backward until the image is as
sharp as possible.
Adjusting the Eyecup
Rotate to focus image
The heavy duty flared rubber eyecup on the Solo R/T
monocular folds up and down to accommodate both
eyeglass weares and non-eyeglass wearers.
• The Solo R/T features a flared
eyecup that blocks stray light when
fully extended.
• Fold the eyecup down when
viewing with eyeglasses.
The Lanyard
Attach to the Solo R/T
monocular in a few simple steps:
1. Detach clip from the lanyard.
2. Push the loop end through the
attachment point on the monocular.
3. Pull the clip through the loop and
cinch tight.
4. Re-attach

The MOLLE Clip
The versatile MOLLE clip allows quick
attachment of the Solo R/T monocular
to MOLLE webbing, a pocket edge or
other equipment.
The Case
The soft case of the Solo comes with a
belt loop attachment for an easy carry
in the field and provides protection for
the monocular when not in use.
Slip the belt loop of the Solo R/T over a
belt for an easy carry.
Note:
Monoculars are not intended for looking at the sun or any other intense light
source. Such viewing could damage the retina and cornea of your eyes—even to
the point of causing blindness.
Caring for the Lenses
Maintain the optical brilliance of the Solo R/T monocular
by keeping the lens surfaces free of dirt, dust, and oils.
Protect Lenses While Out in the Field.
When not viewing, store the Solo R/T monocular in its
custom carry case.
Keep Lenses Clean
Needing to clean optical lenses is part of normal use.
Follow these guidelines for cleaning:
1. Remove any dust or grit from lenses before wiping. Use a
Vortex Lens Pen, a can of pressurized air, or soft camel hair
brush (acrylic optical brushes also work well).
2. Clear lens of smudges, fingerprints, or eyelash oil. Fog the
lenses with your own breath and wipe with the non-abrasive
lens cloth included with the Solo monocular.
Other cleaning options:
Vortex Fog-Free Lens cleaning systems include cleaning
fluid and optical paper for proper care of optical lenses.
You should never use facial tissue, heavy cotton, or fl annel
clothing on lenses—these materials can scratch the lens
surfaces.
