Finally had a reason to try out my bucket sluice concentrator I've had sitting around for years unused. I had originally accepted it as payment for some advertising on the site.
Had a bucket of concentrates from dredging that I'd already panned but decided I should run again as I spotted a small flake escape. Quite impressed, found 4 small flakes that had got away from me panning. Nice and easy to use, quick too. Think I'll be process all my concentrates this way from now on.
