Oldtimer here is a tip for you---Throwaway the multi line scope, especially if you are going to keep shots 35 yards and less-----purchase a heavy crosshair 1.5 to 4 power scope--I purchased a bushnell, dawn to dusk for about $75.00 you can see the heavy crosshairs better in low light, you will not confuse or think about which line to use, with my xbow I can shoot 10 yards to 30 with only 1 inch difference, you can wiggle more difference in impact than that, I also love to use a single shooting stick
