Only had it a short time, & trying to test every setting to be sure there are no glitches anyplace....
First Texas also wants to know how it does in iron. I think it will do great due to things like..
super FAST, recovery speed
The great DD- coil
Tone ID
(there may also be a "process" setting that helps as well).
The F75 seems to have several options to experiment with to go about attacking iron. I have tried 2 so far. Running all metal and watching the screen (what I call "scoreboard watching") for numbers over 15. OR, with a one tone setting in disc mode, where you allow some iron to be heard, you can pick "good" items out by relying on the audio. T2 users have had alot of success that way.....
I've said many times you can't let the look/size of the coil intimidate you. Too many folks have written it off before trying methods that I just mentioned. But, a DD coil can really slice inbetween iron like I've never been able to experience with the older Fisher coils....
