I know I'm supposed to be learning the F19 in all metal mode, but its hard not to use the F75. It is such a JOY to use now. Its amazing to me what I've been missing all these years just because EMI made it unusable for many of my sites. But now that has been resolved I'm intensely pleased at how well this thing works.
The 11" coil is a little much for some of my areas, while the 5" is a little too small in ground coverage. After putting the 10" elliptical concentric on it, I found I really like that coil on the F75, especially in sports fields. Especially in FA mode. I find myself using this mode a lot, often switching back and forth between JE and FA. You may ask why use those settings instead of bP, but I find bP lights up too much iron below my target strata.
I'm really enjoying the FA fast mode. It brings more targets to light than any of the other modes in iron. But it requires a high sensitivity level to work properly. Nothing lower than about a 90, and preferably higher, 99 if possible. I find this to be true for any coil being used with that process. Consider it a basic requirement for FA.
Any tone option will work with FA, but I find I like the single or two tone options the best just because the audio is fuller, richer sounding. Plus, using the single or two tone option allows you to adjust the pitch of the tone. In the all metal mode, the pitch selection changes with every click of the dial, not just the number. It might take 8 clicks before the number being displayed changes. To restate, to change the pitch number from a 1 to a 2 might take eight clicks of the dial. Each of those clicks affects the pitch. You can really dial it in. But I also find that when I transition from the All Metal mode to Disc mode, my ear either looses the slight difference I dialed in by individual clicks inside a pitch number range, or Disc mode filtering takes out the subtle changes. But either way, the pitch changes in Disc based upon the pitch number selected in AM, So I still get the basic pitch change in Disc mode which still allows me to chose an audio target response I like best.
In some of the sports fields that get a lot of competition, where much of the non-ferrous trash has been removed, using FA lights up the ground and brings a lot of new non-ferrous objects to light, both small and large (crumpled tabs being considered large). You may think Ha Ha, Mike found a crumpled tab, yippee, but to me, that crumpled tab could have been a gold ring everyone else walked over because their detector couldn't get it to respond with a diggable signal. I'm digging a lot more non-ferrous gold range targets now in areas where I didn't think there was anything but iron responses left. It suddenly seems like iron is my good friend. Something to look forward to running into because I know if there is something hiding in there, FA is going to bring it to light.
Any of you other F75 owners got to hunt much in FA mode yet?
