After owning a Garrett Ace 250 a couple years back, had it stolen. I just bought a new F2 from Kellyco it will be here by weeks end. Any of you guys compared the 2 before? I read a lot about the F2, and it seems to be better in a few ways than the 250. i also got a great deal with the smaller coil and a Fisher pin pointer. Any pointers you can give on the F2 would be great. Thanks.
