I like what Terry said. When you're starting out you want to try to be versatile. After 22 years of mining I have a mining company in my garage.
Home built and store-bought. If you go to my profile you can see albums pictures of mining gear. when you're out there working in digging, sluicing, dry washing, you start looking for ways to be more efficient to suit your style. Included watching YouTube videos on panning because once you get the concentrates, panning is your last step. You may not see a speck of gold until you get to the bottom of the pan. and before you start working a spot, be sure you do a good test panning before you commit to major digging. After being on this board for a couple of months now, I'm starting to favor the bazooka sluice. But that's for only if you have running water to mine with. I haven't tried a bazooka yet, but the word around here and the videos I've seen, have convinced me it works better than a standard riffle box sluice. When it comes to dry washers, I still trust my Keene. It may be 20 years old. I bought it used seven years ago for $100. It still runs like a champ. the good news is you don't have to re-invent the wheel. There are a lot of good products out there. You may start out like I did, a pan, a bucket, a shovel, and a cement mixing tub from Home Depot to pan in where water was scarce. It's also known as a safety tub for when you're panning out your concentrates. If you hang around here for too long you'll get the gold fever good.
