I need a new relic machine and I am considering the AT PRO. I have good soil here in NC and I am wondering what kind of depth I could expect from the AT PRO on a 3 ringer or a button? I have been using my ACE to relic hunt with for a month and it has surprised me but it just doesn't have the depth. It is a great coin machine and that's what I bought it for, not for relic hunting. I would use the AT PRO strictly for relics but it seems that most people on this forum are using it for coin hunting. Are there any relic hunter using the AT PRO, if so what is your opinion of Garrett's new machine?.........Thanks, Bill in NC
