FA processor on the F75's

I have used it some with the Delta pitch tones. Not an everyday process.
Some of my thoughts using the 5" coil- zero Discrimination
The FA is more susceptible to EMI like the old units were so some areas you can't use it.
FA provides less depth so one needs to crank up the power.
Sometimes really work good in iron plagued areas with 5" coil

I love the FA process. FA acts like it creates targets out of nothing. Stuff that doesn't respond at all in DE will sound off and sound off repeatable in FA. In places where you only get low tones or no tones due to iron and iron masking, FA will light up any non-ferrous and let you know its there.
It does the same thing in non-ferrous trash as well.
FA was worth a new release all by itself in my opinion.

WV62- Ive have tinkered with the FA process. On shorelines with all kinds of slag and metallic fluff, i have surprisingly snagged coins (clad mostly) using it. I also have on several occasions gridded say a 10x10 swaths in different gathering spots that were back filled with all kinds of junk. I would grid with and without the Fa, and each time i was surprised at coins i had missed that the FA setting got. Not necessarily a ton of finds but definitely has something going for it. It still will pick up some large near surface junk signals but definitely will up your take of good targets. I dont use it in place of the regular mode of BP I use, but will do a second search using it particularly if it evident some good stuff is surfacing there. Im going to try higher sense settings in the future as im currently only hitting coins say 2 inches deep. After the initial alert, slow down and study the signal from multiple angles to make your dig or no dig decision. Yes i think it was a valuable addition in my upgrade. CO

I have had my F75 since 2008. I did the upgrade and glad I did. I hunt mainly newer parks and they are full of junk. I have been going back over the parks since I have done the upgrade and I use the FA mode almost exclusively. I am pulling clad/jewelry out of the parks in good numbers using the FA mode. I am finding the FA mode really does find the clad/jewelry right beside the junk. The separation in the FA mode is amazing. I find that the tones in the FA mode are quick, crisp and short. The BP and other modes seem to be a bit more drawn out so one really needs to concentrate when using the FA mode and listen for the chirps and go back over those spots. The FA mode does cause a bit more EMI but I can still run at 99 sens if I want in most instances, but that is not necessary for my clad/jewelry hunting. I am also am using the NEL Sharpshooter coil which makes the F75 lighter and more balanced and those factors make it possible for less arm fatigue and longer trips in the field. If I were to live in an older area of the country that is not as littered with junk and need to go deeper for the good coins, then I would not use the FA mode but probably go for BP. It is very important for an F75 user to know the detector and adapt the proper settings for each type and location of hunting you do. The only way to become one with the F75 is to USE THE HECK OUT OF IT! The more hours you put into the F75, the better you will become at finding the goodies! Give the F75 a fair shot in the FA mode before you knock it!
Interestingly when I used FA mode on an 11-14 F75 LTD2 it didn't seem to work that well. Then I tried it at the same spot with an 01-15 F75 LTD2 and it worked remarkably well. The next time I use it, I want to try it with the 5" coil as I suspect that will really show the magic of FA mode for pulling out non-ferrous targets out of the junk.

Guys I think I'm getting sellers remorse. I agree with what you guys are saying on FA. It's fast just listen close. Do a test in your house/ lay 4 or 5 items in the floor and run your 75 through all the modes and see the FA magic vs the other processes. I will say it is not as deep but it does open up trash spots. Kinda wish I had not sold mine. But I can always get another one. I have always wanted a Troy shadow x 5 so I sold and bought one.

I'll post back in a few weeks. It is suppose to ship today. I've still got my original shadow x2 and I remember all the cool stuff I'd find. 2 knobs 2 buttons and lots of goodies. I had bought a tdi and it was so nice just to dig and not worry about what the screen said I decided to go NON DIGITAL for a while.
If you notch and disc out iron on the F-75 are you still supposed to hear the iron grunt ? I did that on my F-75 and I still hear the iron. I cant notch out the iron on my AT Pro and the iron sound goes away. My F-75 has dst if that makes a difference.
Thanks for any info.

I going to say you may have your notches messed up, very easy to do on the F75. I would suggest you do a factory reset on the F75 and then run your disc up past iron and test it over a couple small nails. I will say you will not hear any iron grunts.
?? what was your disc setting when you noticed the iron problem?

With the machine off push and hold the red button on the panel, at the same time push the toggle forward also hold that, then turn the machine on and let it boot up while still holding the toggle and the red button. Once it boots up you just let go of both the toggle and the button and you will be back to all factory settings.
You can check me, reset is in the manual on the bottom of page 10.
Now about notch and disc setting of 23.
Keep this in mind, if you have disc setting of 23 and then set a notch lower than 23 you will be notching in those numbers, your detector will respond. That is why you are getting iron.
Now if you set a notch higher than the disc setting it will notch those items out, your detector will not respond.
Now we are talking disc 23 because that is the number you were running, it could be any number clear up to max 65 disc setting.
For example, lets say you wanted to run disc 65 and disc out everything, but you still wanted those nickels, you could set a notch to bring in nickels.
For example, lets say you set disc at 23 and set that same notch for nickels you would notch out nickels.
Now I would suggest you get a little more time on the machine before messing with notches, but if you do I would also suggest after done do a factory reset, that will clear out everything that may have got set. You are not alone with the notch problem, we have had several guys that had problems and a factory reset fixed them right up.
If you need more help just ask, there are a lot of guys just waiting for a question, to help.
We need to get you through that leaning curve as quick as possible.
