[QUOTE="AlluvialRic, post: 30031, member: 459"] A couple of things I can see and foresee with this. It is a suction device and by all descriptions is a dredge as it uses a separate pump which sucks water and gravel into a storage device and would be illegal to use anywhere in Australia for the purpose of prospecting/ fossicking. You can not even use an eductor dredge in Australia which is one that relies solely on water suction power via gravity siphoning so I can't see this being legal! Those pumps, even the good quality Jabsco and similar will not take any solids or sand thru them for long. This apparatus would see quite a lot of solids getting past the 'pipe' and into the pump itself. Has anyone yet seen how much gold actually made it up that long pick up and into the PVC catch tube? Unless you are able to pump more than the volume of water which is in that hose on each stroke so that the wash is moved from the riverbed to the catch device in one continuous movement the weight of the gold will have it fall back down and out the hose.
