The Rattler-C V2 50-640 allows any conventional daytime scope 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 12-micron thermal sensor with sub-20mK sensitivity and 640x512 resolution. This gives the Rattler-C V2 50-640 outstanding image quality, as well as the ability to detect human-sized heat signatures from up to 2600 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 Rattler-C V2 to be adapted to user preferences and changing conditions. Other features of the Rattler-C V2 include on-board video/audio recording and image capture as well as Shot-Activated Recording (SAR). Additionally, the Rattler-C V2 is powered by a replaceable and rechargeable Li-ion battery, giving the optic a run time of up to 11 hours, but this can be extended with an external 5V power bank (sold separately).Features of the Rattler-C V2 50-640:Quick conversion of daytime optics into thermal imaging scope12µm high-sensitivity thermal detector, NETD < 20mKFast 50Hz imagingHigh resolution OLED displayAdjustable color palettesOn-board video/audio recording and image captureBuilt-in EMMC storage (16 GB)Shot Activated Recording (SAR)Wi-Fi data transmissionStadiametric rangefinderStandby modeExternal power supply compatibilityWaterproof & shockproof AGM Global Vision Like New AGM 50-640 Rattler-C V2 640x512 50Hz 50mm Thermal Clip-On 314205560206R561-AGM__LN, 7.7" x 2.9" x 2.7"
