I believe the trend of most companies today is transferring warranties. I know most dealers would like to sell anybody a new detector, a used detector with warranty might get people interested in the Fisher brand and possibly buy a new detector in the future. Whites, Deus, and Garrett transfer warranties. Whites and Garrett only offer a two year warranty, but they are companies with "gold standard" customer service. My suggestion is that Fisher offer their five year warranty to the original buyer and cut the remaining warranty in half to the person who buys their detectors used. For an example: If there is three years of warranty left on a used Fisher and the original buyer is selling it, the new buyer would get 1.5 years of warranty. I don't believe this would be too difficult to implement. I for one am afraid and will not take a chance on buying a Fisher detector used. For the record, I have bought eight brand new Fishers in the past and have only sent one back for warranty work. Just a suggestion and would like to hear others opinions.
