The VX-6HD is begging to go where other scopes can't. We gave it new High-Definition lenses for sharpened clarity, and the Twilight Max Light Management System for even greater low-light performance, giving hunters a visible advantage at dawn and dusk when the biggest game is on the move. The new CDS-ZL2 dial locks in place so it cannot be inadvertently rotated off its zero. A mere press of a button will allow the user to dial up elevation, up to 40 MOA (80cm), if necessary. All Leupold VX-HD riflescopes are CDS capable and include one free Custom Ballistic Dial with purchase. To take it totally over the top, we added an in-scope cant indicator for precise leveling, a throw lever for fast magnification changes, and an even more robust erector system. Alumina flip-back lens covers included.MST (Motion Sensor Technology) - An important feature of select Illuminated reticle models is the Leupold-exclusive Motion Sensor Technology (MST). A single touch of the button or twist of the dial activates the illumination, offering several different intensity settings (depending on model) including a high/low indicator. The reticle will automatically switch to "stand-by mode" after five minutes of inactivity, then reactivate whenever the rifle is moved. This eliminates the need for excess movement reaching for buttons, while extending battery life (powered by a readily available CR-2032 coin cell battery)Takes the legendary Leupold designed Duplex reticle and adds an extra-bright center point dot. Ideal for quick target acquisition and the broadest range of game applications.1/4 MOA Finger Click100% Waterproof and Fog Proof2nd Generation Argon/Krypton Waterproofing30mm Maintube6061-T6 Aircraft Quality Aluminum6:1 Zoom RatioAlumina Flipback Lens Covers IncludedBlackened Lens EdgesCDS Custom Dial SystemCDS-ZL Custom Dial System - Zero LockCDS-ZL2 Zero Lock Adjustment with Revolution IndicatorElectronic Reticle LevelExtended Battery LifeExtreme Fast-Focus EyepieceFireDot IlluminationGenerous EyeboxGuard-Ion - Rain shedding coatingPush Button IlluminationReversible Throw LeverSide FocusTwilight Max Light Management SystemTwin Bias Spring Erector SystemZero Lock Windage Adjustment
