Thank all of you for your input. Here is the program I've been working on, to hit an area about the size of 3 football fields. The area i'll be hunting has been camped on/habitated since the late 1800's. In short, its full of all sorts of signals, and due to the lack of time to hunt before the snow flies, my focus will be on finding COINS.
Here is the program i'll be using, and why im set up this way. Again - im not after jewelry or relics - just US coins from the 1800's to present. I cant see any way other than using 5 tones to 1) discriminate at 8 2) hit the coin areas 3) blank out everything else with an "iron" tone to hear the targets im after:
Coil: 9" LF
ID normalization: ON (I know most of you disagree - but to me its easier to learn one set of numbers versus 4)
Ground Balance: Tracking (Ground notch: off)
Sens 92
TX: 2-3, depending on EMI
Frequency: 8
Iron Volume: 00
Reactivity: 2 (dont want to lose depth with 3)
Silencer: 0 (-1 tends to be abit noisy after 1-2 hours at this location)
Audio response: 4-5 (I like to here the deep targets cleanly due to wind, etc)
Notch: none
Disc:8
Tones:
0-8 (251) Iron
9-55 (251) Missing gold, but not willing to dig hundreds of holes due to time constraints
56-67 (901) Nickels hit 61-62 here - this allows for upward/downward mitigation depending on nickel orientation/depth in the ground
68-79 (251) Pulltab city
80-99 (901) Can easily ID big iron in the 96+ range
By using tones instead of notch, i wont lose depth, and ive basically made this a 2 tone program which i'll need with the number of targets ill be getting per sweep. (2-3 per sweep id say - which may not sound bad until you take that times 5-6 hours) I want it to be black and white. By keeping the ID normalization: ON I can switch frequency w/o affecting my "tone notches". Coins will hit regardless of which frequency im in.
In short, I plan to use the "iron grunt" for anything thats not in the coin range. I realize 251 is not the audio tone for iron, so I wanted to ask which value is assigned to iron on the audio scale, because I could never figure it out in the field, and settled on 251

Is it 202 (Ultimate Program) or a different number?
Im all ears for criticism of this program - if you were hunting in similar conditions and your focus was only on US coins from the mid/late 1800's to present (little junk as possible, no focus on jewelry/relics, wanted to utilyze your time for a 2 day weekend hunt) which program would you use, and why?
Really appreciate the input guys
