Got my x-50 yesterday and got a chance to go to an old home site lot that belongs to my brother. I have been hunting there the last couple of days with my Shadow X-3 and had found 3 wheaties prior to today. This was the first signal I got when I got out of the car and went to the area that I have been hunting. I know there has to be some silver on the lot but since the old house burned, there is a lot of trash and molten metal that makes it difficult to hunt especially since I am not comfortable with the x-50 yet. I was running the sensitivity at 18 and I think I needed to turn it down some. Any help you could give me regarding sensitivity in trashy areas would be helpful.
