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.
