The other day Ron Y and I got together for a hunt at my favorite park. During a break we were talking and I told him that I had seen an article about a type of ground radar that would go four meters down and give a visual representation of whats down there. I remarked to him that with the technology we have now I believed that soon we should have detectors that would go much deeper and with increased accuracy. Ron looked at me and said that accuracy would be fine but say, more than two feet of depth would be a waste. He explained that most of us go for coins and jewlery and the places we hunt, Parks and private property, usually would not allow for digging that deep. His answer somwhat surprised me because he's right! I then imagined that I hit a dime target at three feet. Dig or no dig? Thats a lot of digging for target that might just be a Roosie Dime. Not to mention the dirt pile the parks guy would be frowning at. I guess there is a limit to how deep we dig and where at under A particular circumstance. How about all you other guys? How deep and for what would you dig? Your thoughts please.
