A year ago I would have given this a big thumbs up.
I spent the last 4 years without a screen. For relics, that works. But I have to say, I became very discouraged when I started mostly park hunting. I was ready to give up the hobby. Junk, junk, penny, etc, etc. occasionally a nice find in between.
I looked to some of the proven and successful jewelry hunters on this forum to see what they were doing and machines they used. Revier and Southwind are 2 of them and I respect their opinions highly.
This year park, school and homestead finds have soared from any other year, all while digging minimal trash. Other than maybe specific site use, I can't see myself buying another beep/dig machine.
