I'm getting the iron I want. Can run that low if you have lots of square nails. I'll bet nobody has hunted with Manticore with upper disc 2 and bottom disc none.
I was hunting in machine gun iron with upper disc 2, lower disc 0,sensitivity 18, recovery 4, low conductor and audio prospecting. Using a slower sweep. It was running surprisingly good with the lower sensitivity. Unmasking is unbelievable at upper disc 2. I am enjoying hunting with the Manticore at upper disc 2.
I'm not finding much non ferrous but I enjoy digging the iron in northern Michigan. In the past I have found a few Indian Heads and Barber dimes in this area. It has been hunted for a few years.
I check my shotgun shells and this is a Peter Target No. 12 with a big P that was used from 1911-1930.
The round iron looks like a musket ball. It's a little spur sticking up and is about 3/4" wide.
The iron tools I don't know what were used for. I like them though. The iron tool has a V at the end.
Rick..... most cannon balls (including the small ones)...... are IRON!!! But...... round-balls ...... musket balls.....(58 & 69 cal) are usually pure lead.
Yes....... absolutely! = Running Ferrous Limits - UPPER/Ferrous Limits - LOWER.... on: 2/0 is ROUGH!!!!!...... but will bring larger (and more annealed) tools...to the surface.
Right now..... I am hunting a site (removed 1884 house) whereby; I am in:
All Terrain - Low Conductors
Ferrous Limits - UPPER///Ferrous Limits - LOWER = 0/0
This is a interesting setting.......where....... solid iron implements (in my case: mostly nails) will ID as a high-tone squeal. BUT...... flecks/flakes of rust......AND minerals---will ID as iron/with low-tone. My intent is to recover 'solid' iron implements; albeit, heavily rusted.,.,.,.,., so as to: unmask. This config is working..... with phenomenal results. Also: EVEN THOUGH solid nails ID as a non-ferrous (w/corresponding: High Tone)..... you still have the X-Y bargraph to indicate ferrous/iron content of detected target.
Iron Volume = 25
Volume = 25
Sens = 27
Recovery Speed = 4

I am STUNNED as to HOW MANY good (not iron) targets are MASKED! I am also stunned that .... this particular configuration is finding #9 birdshot! These micro-BB's are the size of a grain of sand or grain of salt (about .08 inches......which is 8-caliber).
And to think/know .... that Goldfield Mode is MUCH more sensitive/powerful!!!
Truthfully....... I'd rather...... and I am WANTING...... to use the Pinpoint Mode for all of my work. Problem is...... when you invoke Pinpoint Mode..... the detector will instantly start to: Auto-Detune. I can not afford this...... for the type of work I need to perform.
I've got several articles (on the old forum) that go into depth on high-resolution iron discrimination. The T2 thread..... and the F75 Rcpt Ack thread ..... are two examples........with many folks also giving spectacular input.
I also have a T2se w/11" coil. I'm using 1 tone with disc at 14. I don't think many run the disc that low. At disc 14 it will hit the head of a regular 2 1/2" nail all the way around but as you check all the way around it will not hit the nail at 90 deg. when you get the nail centered. Would most likely hit square nails but in northern MI I like digging them all lol.
I can't find my Manticore charger cord so I'm going to have to order another one. I have it, just can't find it.
I hope you are enjoying using the Manticore at disc 0. Slow going but has to be fun, right. I have yet to try it.
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!!!
If all/most of the solid Ferrous has been removed from you area of interest, now might be a good time to stretch the Salt balance of the Tarsacci on that rusty ground. (or a PI).
That's interesting that disc will not go into all metal.
Did you try Goldfield to see if it will go into to all metal? I'm assuming it will but the number of targets might be over whelming at disc 0 with all the flakes of iron.
When I get a charging cord I'll try out those settings.
