@mfrievalt I don’t know if the others I mentioned are any more sensitive or not, probably not. I do know that you can adjust the sensitivity on mine & it is pretty sensitive, but I have never thought of using it for this sort of thing as I am still doing it the old fashioned way. On the other hand, my only worry is that it will only tell you that steel pellets are there, but not exactly where they are, so you still need to use the old fashioned method to find them.
