The Secutor LRF-C 75-640 allows any conventional daytime scope up to 10x magnification to be quickly converted into an advanced thermal optic. Installation is quick, easy, and doesn't require the use of special tools or equipment. It comes equipped with an industry leading 12µm VOx Uncooled Focal Plane Array thermal sensor with sub-20mK sensitivity and 640x512 resolution. This gives the Secutor LRF-C 75-640 outstanding image quality, as well as the ability to detect human-sized heat signatures from up to 3800 yards away. Heat signatures are projected onto a 0.39" OLED 1024x768 display and are viewable in 4 distinct color palettes – back hot, white hot, red hot, and fusion – allowing the Secutor LRF-C to be adapted to user preferences and changing conditions. Other features of the Secutor LRF-C include on-board video/audio recording and image capture. Additionally, the Secutor LRF-C is powered by 4 replaceable Li-ion batteries, giving the optic a run time of up to 6 hours, but this can be extended with an external 5V power bank (sold separately).Features of the Secutor LRF-C 75-640:Quick conversion of daytime optics into thermal imaging scope12µm thermal detectorHigh sensitivity (NETD less than 20 mK)Fast 50Hz imagingBuilt-in laser rangefinderAdjustable color palettesHigh resolution OLED displayOn-board video/audio recording and image captureBuilt-in EMMC storage (16 GB)Wi-Fi data transmissionStandby modeMore than 6 hours battery lifeExternal power supply compatibilityWaterproof & shockproof AGM Global Vision AGM 75-640 Secutor LRF-C 12um 640x512 50Hz 75mm Professional Grade Thermal Clip-On SECU75-640C-LRF - Excellent Condition
