Pat, you will like it - and you can run 1/4" material through it (which I suspected). When they have it set up as the "Gold Banker", that top section classifies to 3/8" (There's a write up on it in the GPAA Mag, where they field tested it, and liked it. It's another $275). I always thought classing to -8 was more for a quick clean up. It also does a bang up job when you quick class your material (when you have a lot of it) to -8, -12, -20 and -30. It really cuts down on processing time and the sheer amount of black magnetics you have to go through, with the added plus that 99% of the gold will be in the first section after the slick plate (2nd tier). Let it run for about 5 to 10 minutes after you put the last scoop in, and it will do a great job getting rid of a lot of the medium weight material too! I have the 4 tier system, and have yet to find any gold making it to the bottom (4th) tier. The 3rd tier has never had more than 3 - 5 colors of any size. Hmmm, I wonder if adding 2 more tiers will allow you to class to -2?
That's about $200.....
Hard to justify for a little gain.
2 people working together can run a lot of -4 buckets thru it, though, if you ever want to give it a try.
