Some of the reasons for my initial post is because with over fifty-seven years of detecting, I have never been one to want a lot of adjustment functions. Especially many of which are not well defined and allow for too-broad of an adjustment range, the type that can mess up performance.
I enjoy my F75+, but for the different applications I have, I haven't found a need for most o the 'processes' other than 'bP' for wide-open / low-target sites, and mainly rely on the 'DE' process. Not much interest in the others so far.
As for Tone ID, for most modern trash Coin Hunting places I usually use '3' Tone, but for some locations I do opt for '3H' Tones. When hunting any site that has a lot of Iron Nails and other ferrous debris, then I prefer '2H' or '2L' to take advantage of the medium or low-tone Iron Audio. I have no interest in any other the other Tone ID options.
When it come to Discrimination, I only occasionally run mine at '0'. I like to hear some Iron so I never increase it to the '15' break-point and typically start out with my Disc. set at '7' and make slight adjustments if I feel like it.
I never use any Notch Disc. Also, I almost never use the standard 11" BiAxial coil because, to me, it is ugly and just doesn't seem to 'fit' and handle like the smaller-size and mid-size coils I like. Currently I keep the 3½X6½ Concentric mounted and have a mid-size 5X8 DD MGC coil on a spare lower rod for quick changes afield. Both these search coils easily handle at least 95% of my needs, and I do have a brand new 5" DD in the accessory tote with the headphones and pinpointer should I feel the need.
I'll read with interest when others mention why they like different processes and settings. Also, as with almost every other detector I own now or have through the years, I almost always start-up at or near maximum Sensitivity, reducing it, if needed, for EMI.
