gold target i never said i havnt blown gold mate i just said that i have never been able to find any.. at the start i used bucket on the end most of the day and then let my mate thats done fair bit of panning pan it off as he had done alot more panning than me and he was really keen to see how well it worked. after i got used to using it a bit every now and then i would put the bucket at end again towards the end of the day to see how much was going over after running dirt most the day with fair amount of black sand and we still didnt find any. there is always some blue moss showing between riffles when i have the water flow right. if i didnt have enough water flow and no moss exposed between riffles i would be blowin fair bit but i always make sure can see some moss between each one. like i said im no expert but i find the GSA to work well enough for me. although i wouldnt mind building a walbanker as a bit of a project n giving it a run
