Can anyone here give me a definative reason for the use of a punch plate in a sluice or rocker box. I can see using one in a highbanker or dredge but i don't see the need for one in a sluice. Am I off base here or am I thinking streight?

I tend to agree with CP here. My feelings are that one is not really needed in a sluice or rocker box because (hopefully) your material will already be classified to a certain size. Usually 1/4- or 1/8- or smaller. In a highbanker with grizzly, a dredge with crash plate and a trommel, a punch plate is necessary because your material is being classified by the equipment. I might be off base here. What do ya'll think? I'm really trying to justify NOT putting one in a rocker box I am building. I plan to build a small high banker that will definately have one.
