First time Shooting Irons with a diopter cling stuck to my glasses

I was practicing for hardball at the 50 yardline, and my buddy offered me one of those eyepal diopters. http://www.eyepalusa.com/
I can't be emphatic enough about how amazing the difference was. When I shoot irons, and I'm focusing on the front sight, I can't hardly see any black on the target. With this diopter the target shows up very well and I shot this:


The 5 worst shots (ignore those 30cal holes...I was helping a rifle shooter) were without the diopter. The rest of the shots were with the diopter. It's awesome.

Nice shooting Rob!


Are you shooting the match today at menomee falls? EIC match and 1800!

Yup. See you there. Afternoon relay. Do you want to carpool?

It's just a pinhole.  I don't understand how it works, but it is really a night and day difference for me.  Without it, all I see is a manila blur--no black at all.  With it, the black is very easy for me to line up with the Front Sight Post.

If you can see the target even without the black, it becomes a blank target drill.  

Each of us sees a bit differently, and we need to figure out, for us, exactly what we need to see to shoot well.   

Diopters can be very helpful for slow fire, but in rapid, I have found it to be too much.
