They have Laws on metal detectors in the U.S. ?
Oh ya I forgot. First, 60 hrs. of safety training, proper battery insertion and disposal, EPA certification, license to carry a metal detector, finger prints, DNA sample, criminal background check, credit check, drug screening, complete physical and physcho check, 5 letters of recommendation to start. That's just for the state that you live in. for transport or use across state lines you need a Class III
federal M.D. license. That requirement list is twice as long.
And don't forget usage and permit costs.
Metal detector - $500.00
Above listed fee's etc. - $125,000.00
Two 9 volt batteries and a small spade - $9.95 + tax
One rotten zincoln cent - "Priceless"
