Well, like I said once before. I have used the LRP so much that I really don't use the PP function much. You CAN pinpoint holding the MODE switch as well (AM). For the price, I don't see First Texas changing much. As far as detecting, the LRP is a best value for the price. It runs up against detectors like the Tesoro Silver that doesn't even have a pinpoint feature, yet the LRP gives more info and features.
The best detector for buttons is Garrett Ace's. But for the same price, you lose ground balance, large screen and the DD coil. It's a choice, for sure. I'm from the old school before pinpointing. And after years of my Tesoro DeLeon, My F5 and XTerra PP buttons were OK, but I rarely used them. Most detectorists will tell you that, after awhile, your mind tells you exactly where to dig by the way you swing.
