So I've been looking at the CTX 3030 for quite some time now read every forum and thing about it, as well the ATX. I understand there two different machines and the CTX is a professional and great machine why need anything else... Well depth. Max depth the CTX will even come close too is 13" and that's lucky... The ATX has gone too 20" the CTX won't even compete to that not to mention the ATX ignores hot rocks while the CTX does not. I love the CTX because we'll it's fancy, has discrimination... But I want to find stuff worth finding. My main areas of hunting will be mountain areas, large fields, lakes, farms, eastern Oregon (lava rock area many hot rocks) so I'm just curious if I'm wanting an PI machine in these areas I'm describing. If I go to a tiny park, or my backyard yeah I know a CTX would be appropriate but I'm talking about out in the field.
