Excalibur Lumi-Zone Multiplex 2-4x32 Crossbow Scope 1970 

Excalibur Lumi-Zone 2-4x40mm Crossbow Scope with Multiplex Reticle - 1970
Based on Excalibur's famous Vari-Zone crossbow scope, the new Lumi-Zone is a serious low light option made with today's avid crossbow hunter in mind. The Lumi-Zone combines a 40 mm objective lens for maximum light gathering with an illuminated multiplex reticle, making it a must for hunting in the low light conditions when "the big ones" are active. Like the Vari-Zone, the Lumi-Zone features Excalibur's adjustable multiplex crosshair system that makes it possible to adjust crosshair spacing for precisely 10 yard increments to match the exact trajectory of your crossbow at velocities between 250 and 350 FPS.
