I like red dots but only have one (Aimpoint Micro H-1). IMO the biggest disadvantage of them is that they lack appropriate reticles that can be used for hold-over. For instance, I have yet to see a red dot reticle that has defined dots/dashes/lines that can be used for holding-over. Why couldn’t red dots have for example 3 additional buttons somewhere within reach of the shooter that correspond to additional zero locations. For example button “1” could correspond to a red dot that can be zeroed (at any distance per choice of the user) at 100 yards and independently of the other two. Button “2” could be a blue dot that could zeroed at 200 yards and button “3” could be zeroed at 300 yards and be green in color. It would function be simply pressing the button you want displayed on the ocular lens and what ever dot was previously displayed would just disappear the new one would appear. Do we not have the technology to design/fabricate this option?
