The other day I was a little bored and went to a “hunted out park” they had been watering in an area that typically stays somewhat dry most of the year. I was resetting the noise cancel fairly regularly when I got a nickel signal fairly deep and sketchy, swinging from a different direction it was a sketchy penny signal then at 45 degrees a high tone with iron most of the time it was a grunt squeak hoot chirp numbers all over the place. So I dug and there it was, a buff on edge a penny two inches away with a square nail an inch under both. The Ctx is an awesome metal hound it can’t lie you just have to trust it. Oh ya we have some severe mineralization.
