Almost giddy I received my Legend this last week from High Plains Prospectors. I had already given my old Garrett Ace350 to my grandson on the previous weekend. In two days I've collected a ton of non ferrous targets - oil lamps, clock parts, copper straps etx. No coins yet but a number of 12ga shells. One problem I'm having is I will detect a solid repeatable signal in the 44 - 51 range and set the detector aside. I scoop out a shovel full of dirt and pick up the detector and there s no longer and signal of any kind in the hole or in the removed dirt. Pin pointer doesn't find anything. Put the soil back in the hole check it again no sound or indication at all. This happened 4x today. Really dry soil right now. Any thoughts on what would cause a ghost signal like that?
