Rob and all, I'm a proud new owner of a GPX-5000 (courtesy of Santa) and still something of a newbie. I've got 150 or so hours on the Minelab, plus several hundred hours with our GB2 so I am putting in a bit of time. My question: I still struggle to do reliable and accurate pinpointing with the 11" mono coil. I use the edge, practice with nuggets that are visible, and still haven't gotten to where I can 'know' where the target is once I have freed it from the ground. I did use my DD coil at a site up north with a ton of trash and could pinpoint quite a bit better with the DD. At present we wind up using the GB2 to pinpoint if I happen to be out with someone else, and while this works, it slows things down. Any helpful hints? Second question: I keep thinking I should buy the ML pinpointer. However, I notice that no one I know who is an expert and who I trust (and a few of these experts are on this forum) use a pinpointer. Why is that? I have to think the pros know what they are doing and when none of them have a pinpointer that tells me maybe I shouldn't bother. Comments? Thanks for any and all help, Jeff
