I'm not going to tell you how much you will like the F-2, but I will say that I liked it better than all the Aces and low-end Whites. The White's liked scrap wire too much for my tastes and the Aces couldn't handle (bad) ground well at all. They also couldn't differentiate between a nickel and pulltabs, and neither could the White's. The Tesoros can, but they have no target ID meter.
It's equal to the Tesoros for cherry-picking, and it has one very unique attribute in it's operation; If you hunt slowly with it it will serve you very well, but if you pick up the speed to about 4-5 fps, you get another inch or two depth out of it. It's because of it's very fast phase-shift operation, something that the other brand lower cost detectors do not have built into them.
If I didn't have so many detectors already I'd get one just because I liked the one I tried about a month ago so much.
You made a good choice.
