OVERVIEW

NVMT SPARTAN is a new line of night vision monoculars that includes three models - 2x24, 3x42
and 4x50.
NVMT SPARTAN is designed for observation in twilight or complete darkness. This is a passive type
device, i.e. it does not require artificial light, however the new high power IR Illuminator enhances
significantly the picture quality.
The device can also accommodate an accessory IR Flashlight (#29074).
NVMT SPARTAN is equipped with two ¼ inch tripod mounts that allow fixing the monocular onto a
head mount and use as goggles. This device features excellent ergonomics, compact dimensions and
handy controls.
The entire unit is rugged enough for extreme field conditions but damage may occur if the scope is
mishandled.
The NVMT SPARTAN is entirely self-contained and can operate for up to 20 hours on a single
CR123A battery at temperatures ranging from -20°C to +40°C (-4°F to +104°F).

Your NVMT SPARTAN scope is ideal for a variety of professional and recreational uses including the
following:

· Observation in natural environment

· Tourism

· Sporting events

· Search and rescue

· Equipment maintenance and repair

Your NVMT SPARTAN night vision scope was designed to provide many years of reliable service. To
ensure that you
get the most enjoyment out of your NVMT SPARTAN always obey the following Warnings and
Precautions:

· Do not direct a unit in the “on” position at intense sources of light, such as car's headlights or
burning fire. This may disable the unit for an unknown length of time or cause a dark spot in
the center of the field of view. Do not turn the unit on in daylight without the protective cap
firmly secured over the objective lens, as this may damage the unit. Any such damage may void
your warranty.

· Never leave the unit in the “on” position over an extended length of time in an area with a light
level exceeding 1-10 lux (twilight - 10 lux, deep twilight - 1 lux). Please keep the protective cap
on the objective under greater light level.

· Your NVMT SPARTAN was designed to be self-contained. Do not open the body of the scope
or otherwise attempt to service this device. If such need arises return the unit for replacement
or repair.
