NEW Underflow PRODUCT

"Hi: I got the high banker the other day and let me tell yous that I love it... I tried running some cons that had some gold in it and it found the small gold... I'm one happy man... just to watch it work.. Thank you for everything I never thought this old man would find joy in gold prospecting... thank you so much again." .~Mr. Siekert~

"My name is Steve and I live in Northern California. I started mining with a 3 foot sluice and a shovel. I have moved up to a wash table that I load with my backhoe. I really enjoy everything about mining but the cleanup. Like most people I started with a gold pan but just had too much material to go through. I bought a gold wheel and Millers table to help. Not only was using the wheel and table time consuming but also tough on my legs and back and I was still finding gold in my tailings. Standing over the table picking out small pieces of gold just made me hurt to bad plus I was missing family time cleaning up the clean up of my clean up.
 One evening while cruising You Tube I stumbled on a couple of underflow videos. The ones where they were trying to demonstrate the underflow sluice held together with clamps didn’t impress me too much but I was intrigued by the idea. I kept searching underflow on You Tube and found one with Mike showing the finished product. I decided that the idea was so good I had to give it a try. I had the sluice up and running within minutes after it arrived. I have been rerunning all of my blue wheel tailings and finding small and even larger flakes of gold. Not only is it faster, easier and way more efficient it’s actually fun to use. This is by far the best piece of mining equipment I have ever purchased that is easy to use and extremely efficient. If you’re already into mining or going to get into mining buy an underflow sluice first and mining will be fun and we all know that the more fun something is the more you will do it. Thanks Grumpy" ~Steve~

Hi Mike & McKenna,
 Wanted to let you know I got the sluice yesterday, thank you.
 I ran some fine material through it and my reaction so far is astonishment.
 It has picked up well beyond my expectations.
 Regards,
 Steve

The Level of customer service I received was outstanding!! Thank you for listening to me talk about finding gold in Louisiana and not thinking I was crazy, please see the attached picture. As I told you it is super fine and impossible to separate by panning. The dust shown in the vial is from running for 2 hours (about 1 gallon of cons.) with my new Underflow Mini. Turns out I did prove that there is gold in central Louisiana! You just have to look in the right place. I am looking forward to even more gold from the same source. Thank you for re-inventing the age old sluice, it really does exactly as it is advertised.
