JCR, a pi could be interesting. I don't know what it would do on flakes of iron.

What of the Tarsacci?

Posted: **Thu Jul 24, 2025 3:14 pm**

Chris.... that is absolutely correct!!......BECAUSE of the way the Tarsacci ignores salt.....,,,,,,,.........,,,,,,,,, via it's Operating System. This may provide a different "window"........ a different set of corrective-lenses.
I will ALSO try the larger M11 coil on the Manticore...... once I sanitize a bit more area.

Rick........ On Manticore: "Goldfield Mode" is an absolute eye-opener........ and ........ at this point..... I....... ME!!!........ is COMPLETELY unable to handle/process the overload of machine-gun-fire audio...... from the all-metal gold Mode. THIS IS the Mode..... that makes you realise "how" and "why" SOOOOOoooooooo many good targets...are 'masked'.... even at shallow depths.
A P.I. ..... would be almost (but not quite) as sensitive/high-powered overbearing.... as the Goldfield Mode on Manticore.

M8 coil
Sens 27
A/T - Low Conductors
Prospecting Audio
Volume 25
Iron Volume 25
Ferrous Limits - Upper/Lower = 0/0
Recovery Speed 4

Because I am DELIBERATELY wanting to remove all solid nails....... the Ferrous Limits of 0/0 will make any solid nail.... ID with a non-ferrous high-tone pitch. Removing these nails...... has unmasked many (some are fabulous) non-ferrous targets.
So far....... I have cleared all solid nails out.......... in a 14-foot X 25-foot area.
It's been a heck of a laborious ride!
THEN I performed my REAL TEST/curiosity. I was still hearing infinite machine-gun fire iron tones. So I started digging these targets. Turns out.....the bulk of them were badly decomposed nails....... and a infinite amount of rust flakes/flecks. Some of these targets .... were quite large. Even with Ferrous Limits - Upper/Lower on: 0/0 (which makes you think that 'iron' is "off".......and now going to report as a high-tone . , . , . , . , . , . , this is not true. This is to say: 0/0 is NOT a true 'all-metal' setting).......... these targets were still reporting as a low-tone/iron-tone.
My conclusion = These badly decomposed iron targets would still EQUALLY MASK good (non-ferrous) targets!!! THIS HURTS!!! I (incorrectly) thought... that..... by removing the "solid" nails......... most of the masking would be removed. WRONG!!!

Little video showing Manticore with zero upper and lower ferrous limits, sweeping 2 different ferrous objects getting different behavior tone wise with horse shoe button in.

TNSS.......yes. Good video-capture of my preachings! Well done!
PLEASE hold the coil dead-still....... whilst Noise Cancelling!

Rick............. you do have the ability on Manticore to: Iron audio = OFF........... which may achive the "all-metal" mode that you seek to find/use/employ. This will cause ANY metal object to generate a high-tone........ regardless of ferrous/non-ferrous content.
