Just in case some of the members of this site are not aware of the cunning fraud that some buyers out there have been using for years to defraud the sellers of metal detectors on Ebay, forewarned is forearmed. Admittedly, it's probably only a very few crooked people doing this, but it does happen occasionally, and it happened to me twice. It seems that the perpetrators shop Ebay for a detector that matches exactly a broken or non-working detector that they have, or at least one that isn't working properly, in need of repair. After they receive the seller's working detector, they will swap their non-working parts for the working parts. Then the seller gets an email from them stating the one the seller sold them isn't working properly. Unless the detector was damaged in shipment, the seller is responsible to have it repaired, or return the buyer's payment, receiving the non-working detector in return, also paying for the return shipping costs for their efforts. Some people game the system, and that ruins it for everyone.
