I am really new to metal detecting and chose the AT PRO for my first detector what I need clarifacation on is this when I am scanning the ground I have the coil approximately 1-2 inches above the ground and when I get a hit I pin point once I have pin pointed the location of what ever is in the ground. Here is where I need some clarification if the coil is 1-2 inches above the ground and the detector is saying the item is 6 plus inches deep do you actually only dig about 4 inches down. And before anyone answers please do not give me a smart a.....ed answer like get a pro pointer because I all ready have one thanks for any help
