Steve, I read your report on your use of the MDT in a "trashy" area and also watched the video you recommended. I was impressed by both accounts. I agree with you though on your thoughts on the size and shape of the coil, that is, it could be smaller and solid rather than an open design for use in looking for gold. Question, "do inventors listen to you at all about your ideas for improvements, I would imagine some do, correct"? What are the chances this detector could be made more "gold friendly"?
