Built for hunters who want reach, low-light performance, and precision parallax control in one package, the VX-4HD 4-16x50 pairs a 4:1 zoom range with an illuminated FireDot Twilight Hunter reticle and side focus parallax adjustment. The Elite Optical System delivers strong dawn-to-dusk light transmission and glare reduction for a bright, clear sight picture, while side focus sharpens the reticle and reduces perceived movement as you shift between distances. An integrated throw lever allows fast, smooth magnification changes, and Motion Sensor Technology automatically powers down the illuminated reticle after five minutes of inactivity, then reactivates instantly when movement is detected to preserve battery life. The two-turn CDS-ZL2 elevation dial offers precise, repeatable tracking with a push-button ZeroLock system that locks out accidental dial movement and returns reliably to zero. Every VX-4HD is eligible for a free Custom Dial System (CDS) turret matched to your specific cartridge, load, and conditions, letting you range, dial, and hold dead-on. Designed, machined, and assembled in the USA, the scope is built with a rugged, waterproof, fogproof, and shockproof construction and is backed by Leupold's lifetime guarantee. 4:1 zoom ratio for flexibility between wide field of view and long-range magnification High-Definition lenses for enhanced clarity, color, and resolution at all magnification levels CDS-ZL2 elevation dial with two revolutions of adjustment and push-button ZeroLock to prevent accidental movement Compatible with Leupold's Custom Dial System (CDS) for a turret matched to your exact ballistics Illuminated FireDot Twilight Hunter reticle for a precise, low-light aiming point Precision side focus adjusts parallax for a sharper reticle at varying distances Motion Sensor Technology (MST) automatically deactivates and reactivates illumination to extend battery life Integrated, low-profile throw lever for fast magnification changes Waterproof, fogproof,
