I moved from the fisher F4 up to the F75LTD/2 back in 2014. Most all high end detectors have a default set up and others with reprogrammed processes. You can turn on the F75 from the factory, change your disc to zero, find a patch of quiet ground, do a ground grab and then set the disc where you wish and then go hunting. I have pulled a gold ring that rang in as a solid 11 (foil range). since then I only disc 1-6. I keep my sensitivity between 65 & 75 for most yards I hunt, but crank it up in the fields and woods. I use 4H tones for most hunts but in some fields I use 2 tones. I do not use all metal much. I am mainly a coin shooter, but I do appreciate a cool relic and some bling. Sometimes the F75 can be chatty, but's it's easy to flip through the 7 freqs to find a quiet one. If you mess up and set something you can't figure out how to undo, you can always do a factory reset. I say this from experience, on one hunt I tried playing with the notch feature and found it easier to do a reset since I was still new to the machine. To me the F75 is easy to use and has plenty of features that you can grow into. When I was looking for one back in 2014 the standard F75 was $799 I believe. Earlier this year they dropped the price to $599.
I do have an older one that I will sell. It does not have the newer DST upgrade (some swear the non DST versions run deeper). PM me if your interested. I can also set you up with an additional small coil and probe if you'd like.
