I bought mine at Central RC Outlet in Mechanicsburg. They handle Garrett detectors and equipment. They also have gold panning stuff. They are located just off route 15 on Wesley drive. They're address is 1010 Wesley drive suite 11 Mechanicsburg Pa 17055. Phone number is (717)620-8006. Hours are M-F 10 am thru 7pm . closed saturday and Sunday. Very nice to deal with and they will take the time to show you the basics and answer any questions. Highly recommend them.
