The SWAROVSKI Z6i 2nd Generation 30mm riflescopes have all the great features of the original Z6i 30mm riflescopes such as 6X zoom, the patented 4-point coil spring system and HD on the higher magnification models. The new features on the Z6 2nd Generation non-illuminated and illuminated riflescopes include more prominent ribbing on the power ring for easier magnification adjustment and they now come equipped with SWAROCLEAN non-stick coating on the lenses makes it easier to clean away dirt and tree resin. The higher magnification models feature the 3rd turret parallax that can be “locked in” but easily changed by feel. The illuminated models also feature a redesigned, slimmer illumination housing, the overall weight of the scope has been reduced. The day/night control has been redesigned to prevent accidental shut off/on. The Z6i 2nd Generation models also come equipped with SWAROLIGHT which features an auto shut off/on if rifle is taken out of the shooting position, which prolongs battery life.
