The Diopter focus ring WILL have a minimal effect on downrange focus. Shooters with great vision that can have the ring screwed all the way in will find that the Parallax focus knob range markings will be more accurate, while older shooters may find that once the Diopter is focused for their weaker vision will find that the Parallax focus knob range markings will be less accurate. There is a relationship there between the Diopter focus and the Parallax knob. A better plan is the put your scope in a vice and shine a bright LED light into the back of the scope to illuminate the reticle. Do this in a way that the light isn't shining back into your eye, but only on the reticle. So, the smaller the light the better. Then you can get the sharpest focus possible because you will see the reticle MUCH BETTER and easier.
Thanks - great
Will b giving this a try soon. Have a new scope I was sighting in last week. Kept loosing the Reticle. THANKS‼️
