INOD BLOCK III

Description

The Improved Night Observation Device (INOD) Block III
thermal weapon sight provides night/day and degraded
battlefield or weather condition visibility for the U.S.
Special Operation Forces (SOF) Sniper by easily clipping
the device in front of the existing direct view optic. The
clip-on configuration allows the operator to maintain the
existing direct view optic zero.
The INOD employs a completely passive, micro-cooled
mid-wave infrared technology to provide a high-quality,
large format, 640 x 480 resolution image, usable with
direct view optic magnifications from 5x to > 25x. The
proven range detect performance will match or exceed
current Sniper Weapons Systems capabilities. The INOD
has been ruggedized for use with all SOF and U.S.
Army Sniper Weapon Systems. It is ideal for extended
range target detection and identification, observation
of environmental indicators, and is capable of tracking
bullet trajectory making it the preferred Night Vision
Device (NVD) for the Sniper or Reconnaissance role.
The hot-swap battery capability and / or external
power feature allows persistent over watch on extended
missions.

FEATURES
The rear facing focus knob and controls are optimized for
sniper conops. The wired stick remote control replicates
INOD keypad functionality and enables one-handed
gloved operation. Super elevation adjust is incorporated
into the mount to accommodate targeting at various
ranges while ensuring target visualization.
