Does anyone out there have any experience with this machine? I'm thinking of picking one up and am looking for user opinions. I've read a few posts where folks have called it one of Tesoro's all-time best detectors and some others where folks have said that it's superior to the newer Silver uMAX. I believe it was manufactured from '97 through '01 (roughly the same manufacturing time-frame as the Bandido II uMAX). Like the Silver uMAX, the Compadre, the Cibola and a few others, the Sabre's ground balance feature is factory preset.
