What is so different about the. Large holes equal Super fast sifting which leads to more gold! As the innovator of the Hybrid concept, years ago (using small holes in the rear of the scoop to recover small items) I have found it has its flaws. The problem with the design is that it slows sifting. Why slow down your sifting when 95% of the time your target is a "large" item?
Coins, rings, bottle caps, pull tabs etc. A small item works its way through the holes you can snap in our small item insert and recover it fast.
