Copper John boasts the introduction of the round pin gaurd and contrasting aiming ring which immediately set a higher standard After four straight prestigious Best Buy Awards from Inside Archery, they re-vamped their flagship Dead Nuts Hunting Sight product line and have again raised the bar to intimidating heights with the Dead Nuts 2 line of hunting sights. October 1999 marks the year that target sight technology was changed forever. Copper John introduced the A.N.T.S., Always Normal Target Sight. The revolutionary idea behind this new aiming technology is the curved sight frame. This curved frame keeps the lens of your scope flat, or Normal to your eye as the scope is moved up and down the frame. This cuts down on image distortion, increases scope clarity, and keeps the scope reticle normal to your plane of aim. You will always have the same sight picture regardless of the scope's position on the frame.
