I purchased an used machine from Backwoods Detectors in late November. Two months later a problem was discovered with the detector: one about which neither one of us were aware at the time of sale. Richard from Backwoods IMMEDIATELY made it right, without question or suspicion. I would not hesitate to buy from him again and recommend him to those of you who are looking for a new or used detector. He is refreshingly honest and has great customer support!
