Our 2.5 power Vari-Zone multiplex crossbow scope allows hunters to accurately compensate for the trajectory of today's hunting crossbows for up to fifty yards, but focuses their attention in close "where the action is". Sighted at twenty yards on the crosshair, pointers for 30, 40, and 50 yards help hunters to get the most out of their crossbow, and horizontal indexes assist in leading walking game to 25 yards. Other features include an ultra wide field of view, superb optics for maximum light gathering and a matte finish to reduce glare. They are virtually parallax free at normal crossbow shooting ranges, and have sensible 1ln clicks at thirty yards.
