I have a Whites XLT Spectrum for sale. It comes with carrying bag, earphones. I have dug lots and lots of relics. Asking $650.00. Email me for pictures.
Those are good machines...I know a lot of guys down in GA that wont hunt with anything else. You'd probably have better luck selling it by listing it on one of the main stream relic hunting sites or eBay. Whites detectors sell really good on eBay. Just FYI, the Spectrum XLTs usually sell for around $350-$425 used now days.
