Took all my clad found over 30 years to the coin star. Shut the machine down about 10 times from all the dirt. Lady that works there at the market pulled up a chair and just hung out it was shutting down so much. . LOL Wash your coins before . LOL Machine spit out about 200 rotted pennies. Anyways, total was just under $300. I have about 40 lbs of scrap copper/brass I've collected from work and digging. So that's a additional $120 there about. So I'm up to $420. Rest will be out of pocket . Going to buy a second AT pro as a spare. My thoughts are they wont get any cheaper. Going to shop around for just the detector and a pro pointer package. Already have a spare pair of headphones. My brother is buying a second also so maybe get a better deal buying two at one time.
