X22 Low cost affordable cheap thermal FLIR imaging weapon sighting scope

X22 Thermal FLIR imaging rifle sight scope

affordable thermal weapon flir sight SPI is excited to introduce its latest Affordable, full featured, all weather and highly technologically advanced family of X Series thermal imaging weapon sights to the sporting, law enforcement, and military markets. The X22 product line is based on the latest VOx microbolometer hand selected detector core. Each model of the line has optimizing performance, price, and state-of-the-art technology for a variety of uses and mission applications ranging from the seriously committed hunter to the military designated marksman. While primarily designed as a precision weapon scope, the X22 functions equally well in its collateral assignments role as a magnified spotting scope or handheld thermal FLIR imager.

There are many thermal imaging rifle scopes available in the market to choose from, the x22 offers you a full featured thermal weapon sight which compares to units costing thousands more. The x22 offers a great bargain for a robust heavy duty thermal sighting system.

low cost FLIR scope

The X22 is a true high performing thermal FLIR system that is full featured and is catered to the user that wants the most bang for the buck out of a thermal imaging/hand held sight.

The X22 is a solid state, uncooled, long-wave infrared, magnified dedicated weapon scope intended for day and night engagements without the need to remove the sight from the rifle. The 24/7 mission capability is just one of its many strengths. Thermal imaging technology also allows you to detect targets by cutting through snow, dust, smoke, fog, haze, and other atmospheric obscurants. Unlike the use of laser targeting or near-infrared illumination to augment Night Vision equipment, the X22 thermal imaging weapon sight is extremely difficult to detect with other devices, as it emits no visible light or RF energy.

thermal rifle scope DIY Cheap

In addition to being the smallest and lightest in their class, The X22 thermal imaging weapon sights are characterized by their simple and intuitive controls, functions, and features that are layered among direct button adjustments, direct combination button functions, and electronic menu selections. This “layering” of easy-to-understand control functions provides the operator with a framework for customizing preferences and exploiting the robust variety of setting options available in the X22. The X22 has a series of selectable color modes based on a rich, upgradeable software package. A wireless remote switch is included to activate the X22 thermal imaging weapon sight when positioned in the “standby” mode. The X22 has the ability to record videos with optional Digital Video Recorder and is also equipped with a video-out capability in operator selectable NTSC or PAL formats. The X22 uses the same multi- pin connector to provide video-in imagery, where there is a need for map or rangefinder display overlays, and external power access.

The X22 weapon installation is easy, repeatable, and reliable based on a unique and highly user-friendly MIL-STD-1913/ Weaver/ Picatinny rail-compatible, quick-release locking mechanism. The solid state technology and software algorithms, combined with a complementary color reticle platform, ensures maximum reticle contrast, high- level target accuracy, and boresight retention that cannot be achieved with mechanical boresight adjusters and traditional ballistic drums. This level of accuracy is translated into the electronic zoom (e-zoom) function of the X22 thermal imaging weapon sights, which can be progressively increased from 1x to 2x and 4x, without changing the point- of-aim to point of-impact relationship of the targeting reticle.

The X22 thermal imaging weapon sight represents one of the most sophisticated sighting devices available in today’s market to hunters, SWAT teams, and military personnel, due to its superior price-to-performance value.
