[QUOTE="Twapster, post: 73119, member: 1582"] Hi Ace, Most 12v bilge systems I believe use really only gravity to settle the gold, ie...wash rocks....if there's gold...it should settle more quickly than anything else. The larger petrol pumps say 200lpm + add other dimensions to the catching the gold via "vortices"s created by the faster flow that "keeps the gold pushed down", enabling you to clear more dirt yet still leave the gold. A 2.5hp pump only weighs around 12kg ish so not that big, doesn't require a battery and is therefore highly portable and more effective than most bilges. Particularly in high "clay areas", one really needs to wash and break down the clay to liquefy the material. A petrol pump has this ability whereas a bilge does not...to really spray the material almost like a jet blaster to get the gold particles moving freely. That is why most of us use a petrol pump over a bilge......the bilge just cant work the dirt as well, at least none of the bilges i've used! [/QUOTE]
