looking at your photos, I will make these personal comments and suggestions about the MXT Pro.:
• I feel the MXT Pro is the best, most versatile, and easy-to-use multi-purpose detector in White's current product line.
• White's 5.3 Eclipse, a 6½" diameter Concentric wound search coil, has been, and continues to be, the best general-use search coil for that model in most sites, especially those that are brushy, have building rubble, or are otherwise littered with a lot of junk, especially iron trash.
• Each MXT Pro user needs to decide which search mode and settings works best for them in your described types of sites, so here is how I preferred to run it:
Gain: Preset marker to +3
Threshold: Set for a slight audio hum.
Mode Switch: Relic
Tone Option: Iron ID
GB Option: 'Locked' GB and perform an automated GB with Ground Grab to begin the search.
As such, that means the variable Discriminate control is bypassed/non-functional and you will get a Low-Tone audio on
most smaller-size ferrous junk, and a High-Tone audio from non-ferrous targets as well as those iron objects that are, by size or physical design, more conductive than just they ferrous make-up.
Search coil sweeps should be slow and methodical to make sure they overlap for ample site coverage. Then, as skills are mastered, you can ignore recovering any larger-size, probable iron junk targets and concentrate on the smaller-size, more desired targets that are at the site. Ignore most of the visual information, other than noting when a target locks-on solid and reports a target as iron, only.

Still trying to decide if I like this machine! Yesterday evening I went to an old home site. I was given permission by a farmer who said it was his families original home. The only thing still at the site is a barn and tons of junk. Since it was his families and he wanted to see what I'd find, I dug most signals except extreme, loud, big iron signals (I could usually bump the iron with the shovel). The only thing I found that wasn't steel/iron was a spoon.
From the photos you posted, I see a lot of "big iron" I wouldn't have recovered.

I got a lot of signals that indicated NOT iron. I switched to prospecting on these and still got good target indication on a most of them. Usually nails, staples or wire. Actually all were that. When I found the spoon, it was mostly an accident as it was under a large iron chunk, a stove leg.
I wouldn't waste time by switching to the Prospecting All Metal mode to double-check a target.

Suggestions?? I varied setting from normal gain to low gain and usually near zero discrim. I did vary settings later in the evening bumping up discrim but didn't notice much change. With near max discrim I was still finding nails, very small ones too.
You shouldn't have been finding
"nails, very small ones too" at a high Discriminate level setting,
unless you were in a search mode that allowed all targets to respond. Shoot me an e-mail and let me know where in SE WA you are. I am in Arlington, OR, just across the big river, and perhaps we could get together and I would be glad to share some hands-on help.
