Yep had my eye open for a few years on the batteries . 7 dollars for a car battery around my part of the country. I do pressure washing for a job, and alot of real estate companies call to wash a vacant house , seems like theres allways a car battery lying around the vacant house. Picked up a big solid brass chandelier on the side of the road today ways over 5 pounds. Its spring time and I am cleaning up at the scrap yard. Some Dum arse idiot stole over a hundred bronze vases from a cemetary a few weeks ago, then took them to the scrap yard the next day , HA busted idiots. I think we metal detectors do a positive for the enviroment , because of all the crap that we find in the ground that is no good for enviroment.
