I just purchased a Bel GX-65 and didn't want to send in my Whistler XTR-690 for the $80 trade-in. I decided it would be more cost effective to sell it and buy something ultra-cheap to trade in. Little did I know that I would scrape the bottom of the barrel.
I found a "vintage" Maxon RD-3 detector on eBay for $3.99 plus $5 shipping. -Had to remove the pic # unfortunately - on has a picture of the same unit (not the one I bought) if anyone wants to see this relic.
Anyone know anything about them, out of curiosity sake?
