I use a close cousin, an F70.
Hunted with it in great Missouri and Kansas soil where it worked great but also learned to hunt in phenomenally crazy iron in Kansas at a site that taught me much and where I found much, (including a severely masked Walker half), but I had to learn a new language and new behavior to do it.
Last July I moved back to Alabama, red clay mineralization and I live in the city of Birmingham where we have another unusual problem with an extreme amount of iron mixed into the soil from microscopic to huge in some of the parks I hunt because some of them used to be actual dump sites or sites where they knocked down whole neighborhoods decades ago.
Hunting in these conditions I had to learn a whole new and different language and set of behaviors for hunting here but I came across a few different settings that seem to work and get deeper than most I have heard of around here plus find a ton if extremely masked targets, bucket list items like old coins including a seated dime, an SLQ and a Peace dollar among other great things all missed by others in these hard hunted sites.
A few things I learned were in heavy iron all metal works well for me with almost maxed out high test settings which is why I call these blast through settings.
They blast around and through iron to get pieces of non ferrous target signals and if you know what you are looking for you can identify them.
It took me a few hours practice to learn this but it has paid dividends for me ever since.
Another way to hunt in heavy iron is using very low disc and monotone that works well for me.
Disc at 6 to knock out small nails which would be about 20 on the T2 I believe, but I actually get even better results with disc at 1.
Disc at 0 is pretty noisy for me unless I turn down the sense and thresh but I am practicing that right now, disc at 1 gives me a ton of signals but I watch the screen closely, listen to the tones and have trained my brain to notice the better, fleeting masked targets in oceans of iron.
In my difficult mineralized and iron infested southeastern sites I hunt now all of these same techniques seem to work well plus a few more I have experimented with.
Here I can GB up to the 80's in some of the bad dirt, max out the dirt bars on my meter too.
I have found all metal works very well here, also hunting using that one tone does too but I have been successful using most of my tone options especially the lowest 3 which seems to handle EMI better than the higher ones for some reason.
Something you need to know is mine, and yours, both up-average signals around iron and you can use this to your advantage because I sure do.
It helps me notice non ferrous targets in iron sites and in mineralized soil it has the same effect because most if the time mineralization IS iron.
In my soil shallow targets might behave normally down to maybe 2-3 inches, if that, past that the numbers will start to soar so be aware if that.
For instance a normal nickel for me is around 32-33...at 4" it might come in at can slaw numbers in the 50's and a couple if deeper ones at the 5-7" area came in all the way up into the high 80's to low 90's as do all other deeper coins including Indian heads.
As I said hunting in mineralization entails learning a different language and numbers due to this up-averaging effect, learn that and you might be able to notice signals that might be odd compared to normal but will reward you if you dig them.
For a long time me and my friends around here all thought this devil soil limits depth on all detectors because in the bad stuff I have rarely heard if anyone digging targets much past 5".
Now I realize we can get past that mark, the upper end FTP units can anyways, but the signals are so weird and skewed that most never went after them because they do not present themselves as solid, normal non jumping good targets so they remain undug.
I worked hard to learn this new behavior and dug lots if iron at the beginning learning but now I am able to pick out non ferrous items pretty well and rarely dig iron...unless I want to.
Still get fooled from time to time but actual iron both shallow and deep has its own tells and indicators most of the time.
Here us a post about things I learned hunting in heavy iron in good Kansas soil...

Here are some about my learning curve hunting in mineralized soil in the SE. also loaded with iron and others that have the same conditions using Fishers but you have similar settings on the T2 you can use....
