I run one program and one program only on anything other than wet beach. I just tailor my settings on the one prog to suit what I am detecting on. I don't use multiple programs.
Disc = 0
Sens = reduced down to virtually illiminate background noise.
Freq = 18KHz or maybe lower but I am an 18KHz man

Iron Vol = 0
React = 2-4 depending on Iron contamination
Silencer = 2
Audio R = 3
Notch = normally 0 but 01-07 if there is iron present
THE IMPORTANT BIT

4 tones =
200Hz - 0
200Hz - 0
547Hz - 25 or 30 depending on amount of crap targets
791Hz - 93
This allows you to have the discrimination setting at ZERO, where it wan't to be! and used AUDIO TONES for you to eliminate Iron. Low 200Hz tones means Iron, Adjustable with the 547Hz tone, all other tones = DIG!!!
GB - Always on tracking
I use Notch and Reactivity/Silencer to remove Iron noise if it there is a lot but normally NO notch and deffo NO discrimination and put up with the odd blast of Iron noise. Sometimes it is nice to know it's there!
The less discrimination and reactivity you can get away with the deeper you are going to be searching.
I have my Sens set so there is always a bit of chatter going on in the background, not too much but enough to know there is something going on.
Get used to a set of settings, keep your tones on all programs, if your going to use the programs, all the same so you get used to the same tones for ALL progs, saves any confusion.
Remove the programs selections from the Deus, stick with one program and work only with that one and you have a infinitely adjustable, easy to read GREAT metal detector!!
