I am new to prospecting, I have panned in the past and used homemade sluice boxes with little success, but I think it is time to upgrade. I am looking into buying a sluice box and could use any help and or recommendations that you might have. I will primarily be using the sluice in and around Colorado. The two sluice boxes I have been looking into lately are the 36" prospector Bazooka gold trap and the Grizzly 3 sluice. I understand that the grizzly is operated on the bank not directly in the stream or river, other than this can anyone help me with pros and cons of both of these sluice boxes? Also are these new sluice boxes worth it, will not having to classify save me that much time and put more color in my sluice or should I stick with a traditional style sluice like a keene A52 or similar?
