I have a Tesoro Silver Sabre uMax on it's way to me. I have had two Silver uMax's over the years and loved them. Never had the older model (Silver Sabre) and wanted to try one. Read some posts & one guy says the new Silver uMax's are better & deeper than the older Silver Sabre's. Another guy says that the Silver Sabre is deeper and more sensitive to smaller stuff. Whats the real scoop, I am guessing that they are both good detectors after all they are Tesoro's. Steve.
