I agree to a point, it is a mining tool by today's standards with all the BS litigation out there. Doc's videos demonstrate that the Mini Gold Hog is capable of increasing an individual's production rates, depending on the material. I built a boiler box similar to Doc's and attached it to my AM Explorer. I can say without a doubt that it increased my production. The tools the miners can use in this great state (cough, cough) are limited.
