I have it's older brother, the Silver Sabre, it's a good beep-dig detector. These machines are some of the earliest Tesoros, they date to about 1984 or thereabouts. I like mine, it is a turn on and go machine and very quiet in the old rusty square naily tear downs, celler 'holes' and relic sites. When they are set at minimum discrimination on the dial they are well above nail rejection, and when they beep you can almost bet that the target is non-ferrous. They are very popular in the UK on the old Roman spoil heaps as they are about the only detectors that work well there! If you can buy it for $75 and you have a celler hole to work it at, I bet it would surprize you. Tesoro still has parts for these, and the uMax coils work well on them. There was a guy on the Classifieds on here that was looking for one awhileback , and he was from the UK.
