There has got to be somebody that has a vision and knows how deep it goes on a dime and still gets a good signal that says dig me. Would like to know what the graph looks like on a deep coin. If it looks like from what I have seen on a 4.5in target I would buy on.Nobody is showing anything greater than 6in. Please show some pics of deep targets what they look like.Try a dime at 9 or 10 inches. Thanks
