Who's that guy?
Thanks, @jlw ... currently my optics instructor class is on the calendar three times this year - Ohio in June, PA in Aug, and OK in December.I've attended numerous PMO end user and instructor courses, and his, by far, was the best. I also got a lot out of Sig Academy's PMO Instructor course (ignore the "reduces mistake of fact" nonsense stuff".
I took Sig's instructor class, and it is a good class on shooting dots.
