FLIR ThermoSight RX

Thermal Imaging Weapon Sight

The FLIR ThermoSight RX line has performance, price, and state-of-the-art technology for a variety of uses and mission applications from hunters to military marksmen due to its superior price-to-performance value. The smallest in their class, they contain simple controls, functions, and features. The ThermoSight RX can use the HD DVR, Rangefinder and Battery Pack.


The ultimate choice for hunting at night, thermal night vision sees heat, not light so the body heat of your targets will show up clearly regardless of the amount of light available and without having to rely on additional illumination.


From MIL-STD-1913 Picatinny rail mounts with quick-release mechansinsm to user adjustable imaging controls and on-board video recording, ThermoSight RX scopes give you all the features you need.


Solid state design and software algorithms combine to give you maximum reticle controast, high level target accuracy, and boresight retention that even translates through electronic zoom functions so you'll always be on target.
