Nice videos.
If your running 2 tone, back off on the iron volume to about the 3 large segment divider.
You get a better distinction if there is iron and a higher conductor target near each other.
The iron target volume will be lower, you'll still hear it but the higher tone of the higher conductor will sing thru much louder.
I hunt a lot in disc mode when coin and jewelry hunting having the disc set right at the point a small thin gold ring is accepted.
Generally your not digging more than 7" or 8" the most, so that setting works really well. Then you can also flip into 2 tone mode with the same setting
if you want to find even the lower conductors. At tones single tone all metal mode goes a bit deeper or makes a signal clearer for pinpointing.
By switching between modes to check a target seems to help classify a target a bit better. Similar to how I used Tesoros between Disc and all metal modes.
If your hunting in two tone mode with the above mentioned settings and you get a high signal. Pinpoint with the coil. Just when you get to the point where the target signal drops off, if it goes from a coin high to a
quick low grunt tone, the target will be junk.

Keith Southern always seems to get super depth picking up a dime at 12" with the larger coil in the ground, so I was wondering why you could not get it.
I now know why, for Keith's ground test, his 12" dime is not a silver dime, its a reg. clad dime.
