Upgrade your daytime optic with the Krypton 2 FXG50 Thermal Clip-On by Pulsar. The benefits of using a thermal clip-on device on a daytime optic include longer eye relief, a conventional reticle shape, and quick conversion from regular to thermal viewing. The Krypton 2 itself comes standard with a high-performance 640x480 @ 12 µm (NETD <40 mK) thermal imaging sensor that can detect man-sized sources of heat at ranges up to 2500 yards away. These heat signatures are projected on a 1920x1080 HD AMOLED display to provide imaging that is exceptionally crisp and highly contrasted. Heat sources are viewable in 8 distinct color palettes – white hot, black hot, red hot, rainbow, ultramarine, red monochrome, sepia, and violet.
