Explore the Features of SPI STINGER T640-25-S Thermal Rifle Sight

The SPI Stinger is a long-wave infrared, uncooled, thermal imaging weapon sight designed for 24 hours operation, eliminating the need to dismount the unit from the rifle. The housing is made of high-grade aircraft aluminum alloy, making it lightweight, but in the same time tough to tolerate high recoil. The waterproof design of SPI Stinger grants excellent performance even under severe environmental and weather conditions. The device has a variety of modifications providing users with opportunity to choose between a set of different Germanium objective lenses ( 25 mm, 50 mm, or 75 mm) and FLIR Tau 2 detector types (336×256 or 640×512), which allows the operator to achieve the most suitable performance for the tasks he faces. The Stinger’s user-friendly interface, comfortable and ergonomic buttons, together with the wireless remote control, makes adoption and application incredibly simple. The Stinger includes a variety of color palettes and reticle patterns, adjustable image brightness and contrast, an internal menu, and digital zoom. Optionally the capabilities of the device can be extended with WiFi module, external video recorder or monitor. While long term missions any commercially available battery pack can be connected via micro-USB port to drastically increase operation time.
