FLIR Scout II 640 Thermal Monocular is a handheld thermal imaging device designed primarily for outdoor enthusiasts but can be useful for anyone. You can view, record, or relay images and videos of thermal signatures through fog, smoke, and foliage during the day or at night. At the core of this device is the 640 x 512 VOx uncooled microbolometer that operates at a 9 Hz refresh rate. This thermal imager features a 33 mm lens with an 18 x 14degrees field of view, a 2x to 4x digital zoom, and a number of palettes and digital enhancements like the FLIR Proprietary Digital Detail Enhancement. You can view scenery on the built-in 640 x 480 LCD display or relay NTSC or PAL videos to external displays and recorders. To enhance user experience, the monocular offers a simple but effective control pad and an in-view menu.
