[QUOTE="WalnLiz, post: 184075, member: 147"] G'day Kezz, 1200 is long enough mate and 300 wide will work ok for that length, especially if it's mainly gems you're after. 210 L/min will be plenty for a gem banker as you need less water pressure with these than you do for gold only bankers. The idea with the gem configs is to catch as much of the heavies as possible compared to flushing these heavies when mainly chasing the gold. Stick to more vertical riffle arrangements and shake the banker sideways about every 10 shovels of wash. This will settle the Sapphires, Zircons, Garnets under the iron-stones and Spinels and help keep most in the sluice. This will also sink any gold firmly into the matt as well. Best of luck out there, Wal. [/QUOTE]
