The way things are travaling here in victoria id be building the biggest and longest sluice box you could physicly carry, stopping short of punching roids to get the big girl down to your favourite digging spot and start pumping through the dirt in cubes not shovel loads.
The old timers were not wrong where to dig for gold, they were not wrong about how long to have their sluice boxes, i work mine out on the size of sheet metal you can purchase, 1200mm, 1800mm,2400mm, maximising the use out of a sheet, left overs make hopper boxes, slick plates and riffles.
As the not so well known famous actress "Belladonna" once stated, " length and girth baby, length and girth" :lol:
