I agree that the AT's can get down there when set up right, because I have done it. But I also acknowledge that I see guys pull up deep silver from "hunted out" sites with high end MineLabs. It's just a fact of life and I feel no jealousy or whatever about it. Those high end machines go deeper, particularly in skilled/experienced hands. I realized a year or two ago that there are coins out there deeper than what my ATP, and my skills, can detect. I see it when a lawn or boulevard is ripped out etc. and I find a STILL DEEP 1910 silver dime or whatever. A few times I have realized that some signals were over my head depth wise, for whatever reason. As someone said before, this hobby is about having fun, and I get that in spades with my ATP. But if someone is seeking deep silver, are there stronger machines out there for it? Yes. Is the Minelab CTX3030 more capable of finding deep old silver than my AT Pro ? Yes, but it is also 1/3 the cost. I can live with all of this and enjoy myself out there. If you have a CTX you have a top end machine, and I wish a good day to you sir.
