The AGM Spectrum LRF 4K digital day & night vision scope utilizes many of the features that shooters have come to know and love in the Spectrum-IR, but with one big addition: a 1,000-meter integrated laser rangefinder (LRF). This feature helps alleviate a common issue many shooters find themselves experiencing when hunting with any sort of digital optic, and that is the lack of depth perception that is inherent in optics utilizing a digital screen. The Spectrum LRF 4K pairs that LRF functionality with an advanced high-resolution 3840A-2160 detector, which works in conjunction with a high quality 1920x1080 OLED display. The Spectrum LRF 4K is one step in the continuous evolution of full color digital electro-optics. New and improved 4K digital sensors are now naturally more sensitive to infrared than older models once were, which means the unit should require much less external Infrared light while used in night mode.The incredible new adjustable aperture provides traditional daytime hunters with increased low light gathering capabilities that exceed that of some of the highest-quality traditional glass hunting optics. The Spectrum is literally built for prime, legal daytime hunting hours in the precious minutes just after sunrise and just prior to sunset. Powered by two internal rechargeable 18650 and one additional replaceable 18650 batteries, the 11hr battery life supplies users with more than enough time behind the eyepiece during hunting season.This unit is also one of AGM's first to utilize a semi-circular display, an on board ballistic calculator and 1000yard integrated laser rangefinder, as well. Along with the new 4k high resolution CMOS sensor, we thought it prudent to also update the internal storage capacity, which now comes in at a robust 64GB, which will come in handy when recording in higher resolution. If you're looking for an exceptionally capable technological optic, the Spectrum LRF 4K is the perfect addition to your arsenal.F1.2-2.5 adjustable aperture provides incredible low-light gathering capabilities3.5-28x incremental and step zoom capability3840x2160 ultra-high-definition CMOS sensorBuilt-in laser rangefinderSupports Day/Night modeDetection range up to 1,000m (day)1920A-1080 resolution OLED displayVarious reticle types and colorsInternal ballistic calculatorOn-board video/audio recording and image captureShot-Activated Recording (SAR)64GB EMMC built-in storageWi-Fi data transmissionAGM Connect App compatibilityWaterproof & ShockproofStandby modeDual power systemUp to 11 hours continuous operationExternal power supply capability3-year warrantyIncluded : Two Rechargeable 18650 BatteriesBattery ChargerUSB CableLens ClothUser ManualQuick Start GuideCarrying Case
