Iron Buzz -- as vferrari noted, but not "explicitly," FE=0 is the same setting as F2=4. So, if you were running FE = 0 before, and you run F2=4 now, you are running the same setting. Since you were running FE=3 before, I'd try F2=5. From there, you might try gradually bumping F2 downward, as you get used to the "falsing."
To elaborate (for those interested)...
The lower you go with your F2 setting, the more "iron falsing" you should hear, BUT, on the other hand, the better your machine will also be able to "unmask" a coin that is lying near an iron target. Reason being, high iron bias settings can "filter out" a good target next to an iron target, by assigning the entire "composite" target (the iron target and good target) an "iron" ID and tone.
I think a good rule of thumb is to run HIGH iron bias, as a newer EQX user. Doing so, you won't dig as much iron (iron targets will ID more "solidly" as iron), and thus if you hear something that "sounds good," there is a better chance it is indeed "something good" -- i.e. a non-ferrous object. BUT -- the caveat is, you also should be aware that a coin that is co-located with a nail will be more likely to be assigned an IRON tone, when running a high iron bias setting (as I mentioned above).
THEN, as you gain some experience with the EQX's audio, you will get better at learning the difference between a high-tone iron "false," and a high-tone emanating from a good target. At that point, you can then begin dialing down your FE (or F2) setting. YES, you will hear more "iron falsing," but since your experience with the machine will allow you to be better able to tell a "false" high tone from a "good" high tone, you can deal with the extra "noise," while in the mean time you are increasing your odds of having any non-ferrous target that is lying near an iron target report as two distinct targets (a low-tone/high-tone mix), instead of the machine just reporting it as one low-tone (iron) target.
What it boils down to is, as you learn to recognize a high tone that is an "iron false," from a high tone that is actually a non-ferrous target, you can begin to use your BRAIN -- i.e. your knowledge of the EQX's tones -- as the "filter," and thus rely less on the EQX's "electronic filter." Exactly where you choose to set that "break point" (i.e. do you want the MACHINE to filter out the iron falses, or do you want to let your BRAIN filter them out), is up to each individual and their experience and comfort level with the EQX's language. Personally, I like to minimize the ELECTRONIC filtering, and let my BRAIN do as much of that "filtering" as possible, but -- without overwhelming myself with noise/false tones. Gradually, as my experience with a new machine increases, and I learn more and more of how to "filter" (ignore) the falsing mentally, and treat it as largely "background white noise," I can then "tolerate" more "falsing" without becoming overwhelmed and mentally fatigued. And again, there's a payoff to dealing with the "noise" -- you allow yourself the opportunity to allow the machine to point out a few more good targets to you (those high-tone/low-tone mixed type of signals) than you otherwise might have (with iron bias set high).
As vferrari has said elsewhere, there is no "free lunch;" there is always a tradeoff. Set bias high, experience a quieter hunt, but potentially miss a few coins that are co-located with iron. Set bias low, and you'll experience a "noisier" hunt, but you might nab a few extra coins, that otherwise would have ID'd as iron, if you had been running a high iron bias setting.
Hopefully, that was clear enough to be understandable!

) have found that a couple of notches of F2 may actually be called for in some situations. But I am still learning how to use F2 in different situations.
I should’ve known that was coming from somewhere....
