The dot is PROJECTED into the sky. It appears on the same focal plane, as the target.flinch wrote:....In other words how RS eliminates the problems, when one eye is looking in the sight and the other is off sight?
The only way that I can describe the effect, is like a laser pointer, on a white wall the size of the Universe.
There is all kinds of stuff in our near-field vision, that we automatically "block out" of our concentration.
When you use a reflex sight, the only two things that you pay any attention to, is the target and the dot.
The entire gun, and even the sight housing that surrounds the glass, just becomes an out of focus blur, that you don't notice, or even care to notice.
Barrels, ribs and beads lie.
They depend on your ability to "line things up".
When shooting on the wing, you don't have time to "line things up".
The dot doesn't lie.
Once it has been set to point the same place the gun shoots, it will never lie to you.
Where the dot is, is where the pattern is going to hit.
