After using more detectors then an ant farm the past few years....I figured I would preorder order a F22. I had a f2 with a DD 11" and was very impressed.....the T2 had a lot of work on his hands to be dramatically more powerfull.......right now I have fisher 1270,whites idx and whites classic 3 plus...now the whites can hit all coins in my garden and the 1270 can too! The only difference is the 1270 hits the deep coins louder and the low conductive metals a little better. However all three machines don't do so well on a quarter 6" deep with a square nail next to it. I found the digitals do a better job at that with multi sound, they will chirp a high tone in there. If the f22 does better in my test garden....see ya later 1270.....
