I had an F2, it did get deep targets and I found some goodies with it. Could be annoying in wet grass or wet areas, and loves to show iron as a strong signal. I upgraded to an F5 and have found it out performs the price range and gives you some more tweaking abilities. Either way, both machines have found coins at 12+ inches and buttons at 10 inches. The F2 found a lead pipe at over three feet, go figure!
