The SA32-25LRF is a compact and lightweight multifunctional thermal imaging device with a 35mm lens that integrates a laser range finder effective up to 2100m (6890ft). It is streamlined, balanced and lightweight. At only 14.8 oz (420g), it easily mounts on your favorite rifle with the included aircraft grade aluminum mounting bracket. It features a 1-4x digital zoom magnification that enlarges the target. With a 7.5 field of view (FOV), you have a great sense of where the target is in relation to the environment. Resolution of the eyepiece is 1024x768 OLED and backs up the 384x288 thermal sensor allowing the SA32-35 to sense targets at up to 2000m (6560ft). With the next generation vanadium oxide IR detector pixelation of 12m (micrometers) and a Noise Equivalent Temperature Difference (NETD) of ?25mK, you get an extremely sensitive device that performs even when environmental thermal contrast is low at great distances. The SA32-35LRF offers five thermal display colors for varying conditions and a refresh rate of 50 Hz. The 18650 removable/rechargeable battery provides up to 5 hours of use and can operate in temperature between -20 and 140 F. Conveniently carry a couple extra rechargeable batteries to avoid having to leave the field due to a dead battery. The Ingress Protection (IP) factor rates at an industry leading IP67, providing 100% security against dust and submersion in up to 3ft of water. The SA32-35LRF also features technologically advanced features such as a ballistics calculator, One-Shot Zero, PIP mode, Blind Pixel supplementation correction, Time/Date image stamp, Auto Hot target tracking, Wi-Fi connectivity to your mobile device and video recording for your shot record that can be save to a 128GB SD card.
