There are at least three advantages.
(1.) The dot is projected into the sky, and placed on the same focal plane as the target. You can put the dot right on the target, and have both it, and the target be in focus at the same time.
You can't do that with a bead. You can either focus on the bead, or you can focus on the bird. You can't focus on both at the same time.
(2.) The dot moves on the surface of the lens, and stays on the point of impact if you move your head.
If you put the gun in a vice, with the dot on the center of a pattern board, no matter where you move your head, the dot stays right in the center of the board.
Up, down, left, right, it doesn't matter. Where the dot is, is where the center of the pattern is going to impact.
Sure, the dot moves around on the lens, but a bead will move all over the board. And where IT
is, isn't where the pattern will hit.
(3.) It is impossible to see the wrong dot. Only one eye can see the dot, so there is always only one dot.
Both eyes see a bead, so if your focus is on the target beyond it, you DO
see a double image of the barrel and bead. Your dominant eye makes the one in front of your dominant eye "stronger", but that is easily fooled.
Try this. Stand 20 feet away from an object, extend your arm, and hold your thumb up. With both eyes open and unobstructed
, focus on your thumb, and you will see the object beyond, as a double image.
Then, shift your focus to the object 20 feet away, without moving your arm. Now, you will see a single image of the object, and a double image of your thumb.
If you always pick the correct "thumb", you will hit where you point. However, we aren't all so blessed. And it is still possible for your non-dominant eye to "take over" and have you select the "wrong" bead.
