I ordered a 12x45 Half n Half sluice from South Yuba Mining a while ago. Have only had the opportunity to use it once so far at Nundle. Very easy to clean and was catching very fine gold. Nothing of size, but that is probably because there was nothing of size where I was
I will put a pick up later, don't feel like walking to the shed in the rain right now.
Total cost from memory was $220 delivered. Mind you the exchange rate is better now
A dredge/highbanker hopper can be added to it. Very happy with the build and quality.
