I have a couple of questions about rules within the public fossicking areas.
You’re not allowed motorised things, would a paddle powered water pump that moved water from the main flow to the top of your sluice off to the side out of the water be fine, I mean it’s not an electric or petrol powered motor, it uses the water to turn a wheel that pumps water up a hose, there are various designs and they just save you the effort of walking buckets of dirt/sand from where you shovel them down to the sluice?
Your sluice is supposed to be 1 m x 200mm but it sounds like they don’t care that much about the length or the width, in that I think most commercial designs seem to be slightly wider than 200mm, and nobody seems to be talking about getting in trouble for slightly larger dimensions than the rules.
Also a 1m long 200mm wide high banker would technically not break these rules, do anybody use high bankers, I’ve not heard anybody talking about using them, which I presumed was because you’re not allowed a motor powered water pump, but a paddle powered pump would facilitate this, if it was allowed.
