This is our first season with a Minelab detector. My fiancé and I are both using the Minelab equinox 800, and loving it! We headed out to a local park that I had looked up on the old plat map, and we started detecting where an old farm had been. We found a lot of clad most of the time, but it was good for learning the machine. Then I had a hit that sounded totally different than the clad and it was a solid hit each way I swung. To my surprise it was an old medical device plate for a machine to cure deafness. This device was patented in 1903, and my plate said patent applied for, so it was even older. Upon doing so more research, this doctor was found to be a fraud! He was even listed in articles as a "Quack Doctor"! https://www.antikeychop.com/dr-powell-s-vibrator
