Description Sierra3BDX Riflescope Features:Integrated BDX Ballistic Data Xchange. A rangefinder and riflescope system that uses ballistics, environmental conditions and Bluetooth to illuminate the exact holdover dot. Automatic holdover dot on a Digital Focal Plane, combining Second Focal Plane stadias, with an OLED illuminated ballistic holdover dot that automatically scales with zoom to subtend on target at any magnification level. Features our MOTAC (Motion Activated Illumination) that powers up when it senses motion and powers down when it does not. Provides for optimum operational safety and enhanced battery life. Spectracoat highly efficient, ultra-wide broadband, anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission. SIG SAUER's innovative KinETHIC kinetic energy transfer indicator. KinETHIC provides assistance in assuring an ethical hunt by indicating when energy on target drops below a threshold that can be set by the hunter using the SIG BDX App. New for BDX riflescopes, Auto LevelPlex, automatically increases digital level sensitivity on longer shots. Dependable waterproof (IPX-7 rated for complete immersion up to 1 meter) and fog-proof performance. 20 MOA Travel per Rotation 10 Daylight Illumination SettingsKilo1000BDX Rangefinder Features:5x20 mm monocular with SpectraCoatTM anti-reflection coatings for superior light transmission and optical clarity. Revolutionary Lightwave Technology for the fastest and longest distance rangefinder engine. HyperScan provides 4x range updates per second in scan mode while RangeLock reports the last range result when ranging distant targets. Includes Line-Of-Sight (LOS) and Angle Modified Range (AMR) standard rangefinder modes as well as Applied Ballistics Ultralight (ABU) mode for use with the Ballistics Data Xchange (BDX) system. Units in yards or meters to tenth Y/M resolution. Ultra High Transmittance second generation Liquid Crystal Display (LCD) for superior low light performance.
