Is "0" disc the same as All Metal Mode on the F75se

[ramer]

If I am using 0 disc, is this the same as using All Metal mode? If not, what is the advantage of using All Metal mode? I don't like using All Metal on the F75se because it is mono-tone meaning you have to keep your eyes glued to the display. The tones or lack thereof in All Metal only get louder or quieter depending on how close or big the target is, which to me is a worthless "feature."
Do all high end detectors behave this way in All Metal modes? My xterra 50 in All Metal mode has 3 different tones to indicate what the target is.

I've been experimenting with this subject on the F70 as well. I like to run 0 disc with tones instead of allmetal (monotone) on the beach or any other relatively clean site...its too dang chatty anywhere else to not run at least 1 disc with iron notched out...I dont like to have iron notched out on the beach, since a guy can find knives and lighters and whatnot in iron, plus, bobby pins are a good sign of an area that needs to be focused on..so I hope somebody chimes in and lets us know what allmetal's intended purpose is.

I seldom use all metal myself, but the few times I do it is on the beach, where I dig almost everything, anyway, and on those rare occasions when I run into some really bad ground. All metal is the deepest mode and punches through highly mineralized ground better then the disc mode. HH jim tn
