Welcome to the forum...from Portugal, yet.
One of my favorite YouTube reviewers is from your country, DJLsb Tech, he does drone and phone and all kinds of reviews although I am mostly into his vaping vids.
Daniel knows what he is doing even though his English accent can sometimes be a bit off and funny.
Using your current settings a larger coil should get you a bit deeper, I have been messing around with my new Cors Cannon coil and it does seem to be deeper than that 11" DD coil on my F70.
Another way to get deeper is to raise your threshold to the + region...the higher the better and try to get up to +4 at least if you can.
Yea, it can get noisy at higher levels and you have to train yourself to get used to the jumping and chatter but as always if this thing passes over a good target it will stop acting crazy and tell you in some way.
When you raise that threshold setting in effect you are actually lowering the threshold level to deeper levels in the ground so your rig will sound off on and react to targets laying deeper that it would not with the thresh set lower to your level.
I know quiet hunting is much nicer and too much noise is not all that fun for many but if you can adapt to higher, hotter settings the rewards might be great.
Once, when I was new less than two months in with my F70, in a park with great soil I was able to get my sense up to 99 and my thresh up to +9 and it was pretty darned quiet there for some reason....I was in DE and not SL, also, and using the 11" DD coil.
I was in 1F at the time...1, 1F and 2F are going to be your quietest tone choices if you are going to turn up the gain and thresh to super hot levels.
On this one special target I did try other tone settings before I dug it and I hit this thing using them all.
Man, I was coming across some deeper targets using those settings that day, easily 8,9 and 10" or more and I did come across this the deepest target I ever dug using them.
It was this thumb ringer part off of an old bicycle bell in the pics below.
Not only was it solid and loud but it repeated from all directions and I got some numbers on the screen the whole time.
A little jumpy, from lower 20's to low 30's but the mid 20 numbers popped up more often than any other.
I saw 14-15" on my depth reading and I was so curious I went after it even though I was in a public park and I never do that.
This thing was every bit of 15" deep, I measured it at the time because my mind was blown.
Turns out the thing came in at 24 out of the ground so those mid 20 numbers were pretty accurate even on something this deep.
On real deep targets you should still get audio but the screen will usually go blank...not on this one with that high gain and super maxed out thresh setting.
Another way to get deep and still be somewhat quiet in disc is using what I call my Silver Slayer Settings.
Turns out just like using different combinations if the sense and thresh to quiet this non DST unit down the disc control can also be another tool you can use to mitigate jumping and chatter.
Turn the disc up to max, 65, and at most only notch in one or two other sections below that...the most common areas for the targets you are looking for are the most obvious.
Don't know why this works but it does, in areas that are super noisy with the sense in the 90's and the thresh only up to about -1 or 0. And disc at 20 or below when I do this I can frequently max out both the thresh and sense and still be shockingly quiet.
You can try notching in more than one or two areas but I have found the more you do the noisier it can get.
Yet another way you can get deep using that 11" DD coil or any coil is by using all metal.
This took me some time to learn to do, actually time to just get used to it, but by going to all metal for a few minutes on every hunt, (and pushing the gain and thresh setting higher and higher over time), I got used to seeing a whole lot of action on the screen and in the audio and eventually I learned to pick out the good signals from the falsing ones.
For years now my program two has always been sense at 99, thresh at +9 and SL speed in AT...not only do I use this as a check when I hunt in disc but I actually hunt using these a lot because I have very difficult soil and these settings work well to combat it, and iron heavy sites also I have found.
Curiously, using these maxed out all metal settings is frequently less crazy and jumpy for me than using disc and much lower sense and thresh settings at those same sites.
Again, don't ask me why...they just are.
I discovered using these blasted out all metal settings work well quite by accident one day when I was hunting in an area of a public park that had more EMI issues than any other site I have ever hunted before or since.
After that, and much practice, all metal became one of my main ways to hunt and still is to this day.
Which technique and set of optimum settings would be best for you all really depends on your particular soil conditions and how deep your targets are which, duh, is always true.
Using all these techniques I have found I could get massive and shocking depth in very good low mineralized soil using normal factory coils and surprising depth in the very bad high mineralized and iron infested dirt I hunt in now.
That Patriot has a huge amount of control over so many settings so I say why not take advantage of them all if you can?
If you can take the time to slowly learn to hunt on higher and hotter settings and eventually get used to the extra chatter I can tell you for a fact this can be quite big advantage to you in the kind of sites you are describing.
I have done it for so long now no amount of jumping or chatter bothers me, it all seems comfortable and normal to me now.
Even though I do also feel like hunting in a very quiet environment sometimes I always know if needed I can hunt in more than just one way and I have a whole lot more treasure in my collection because I gained these skills over time.
In our world, effort+knowledge=success...an equation I have learned to live by.
