I have been searching for lost treasures many times before at an old 1790's homestead with several different detectors....but it wasn't with a Sovereign GT with the iron mask feature! After selling my other detectors and purchasing my Sovereign GT, it was time to re-examine all the spots I detected in the past.... So here I am swinging along where the home use to be. (approx built in the 1790's) So much garbage and so many loud metal signals ( old cans, pipes, old car parts, etc etc etc) my head was ready to blow off lol. I kept on saying to myself, ( not only today but many times over the last few years) "There has to be something here at this is an old home. They had to of dropped something....." so after covering the lot where the house use to sit, I walked across the old driveway. (Settings: Audio is set to max, iron mask on, auto sensitivity, disc and notch off, light threshold).
