Vent: My metal detector was giving me junk signals until I changed one setting
I was out at an old farm site near Lexington last weekend, a place that's been picked over for years. My Garrett Ace 400 was going nuts on every little piece of rusted tin can, and after three hours I had a pouch full of modern trash. I was ready to pack it in. On a total whim, I dropped the sensitivity from its max down to about 60% and switched the discrimination to ignore iron completely. The next signal was a clean, high tone. Dug down maybe eight inches and pulled out a complete, early 1900s pocket watch casing, no glass or works, but the brass was in great shape. It seems the high sensitivity was amplifying all the ground noise and tiny iron bits, masking the good stuff. Has anyone else had luck with turning DOWN the power on a site like that to actually find better things?
