While I have never used an F2, according to UPS tracking, I should be taking delivery on a F22, Thursday afternoon.
I set out wanting an F2, but changed my mind right at the last moment, because:
Daniel at metaldetector.com, explained to me that the F22 was an improvement on the F2. So I says, "wow, the F22 ought to be a monster, cause that's what the F2 seems to be."
That's really the only reason.
Of course human nature always dictates that we second guess ourselves.
I could have bought an F2 for $199.00 with 2 coils. I ended up spending $289.00 for the F22, including an extra coil, the 8" round concentric. So, almost a hundred dollars difference.
Also, digger27 has written volumes on the merits and his success with the F2.
So, that's why the second guess.
So Larry, I am wishing you and I huge success and lots of fun with our new toys. I feel confident that we will to the extreme. Just gotta get out there.
The bad thing is I ordered mine full knowing that I am scheduled to have right risk surgery Thursday, and will have to wear a splint and limited use for the next 5 weeks. Bummer.
