[QUOTE="gcause, post: 34638, member: 1497"] What's everyone got against bubbles don't you realise that is what gets you the gold? It's when the bubbles form due to eddy currents generated by the riffles in the sluice that the gold (even flour gold) will drop out of solution and get trapped behind the riffles. Remember gold is 19 times heavier than water so the bubble won't carry it. You want you bubbles to be showing just behind your riffles as that's when you know you have your water flow right. The other thing about a sluice is you should only have one form of matting across its length and get the water flow right for that matting. Seen lots of multi matt contraptions on forums lately that loose gold because they can't get water flow correct, the multi matting is one of the reasons the other is the angles they use but the bubbles will tell you if you have the right angle.
