Say if I was hunting in a real trashy public park and only wanted to accept nickels and zinc coins and above. Would I be better off running the discrimination up to just below nickel and then setting a notch for the stuff in between nickel and zinc or set a notch from 0 to nickel and then set another notch from nickel to zinc? Make sense. What would be the pros or cons of doing it both ways. I heard using discrim will cost you depth. Is it the same with the notch. Thanks.
