Here it comes...…… a bit of a paradigm-shift in technology/technological-advancements. I want to give you guys a (moderate) heads-up...… for something that is on the horizon. It is built by a small company (medium/small) that makes military-grade underwater locating devices. One of those engineers is a avid detectorist. He has convinced/steered the company into inventing/building a hobby-line detector. It's been in-the-works for about 18 years. All of the prototyping had been completed 2 years ago. It has been an "unreleased" completed product for the past 2 years. (((We are at: "shoot the engineer" time-continuum))). It is not quite a VLF..... and it's not quite a PI. Ergonomically..... it has been 'pushed' to be in the shape of a detector...that we would 'recognize' as a detector. It's been some work..... to get the unit to 'sound' like a metal detector. . . . . . that we would 'understand' it's language/audio. It is "quirky". You will like some of the quirks.....and can put some of them to good use. Some things that I can share...… at this time: * Very specifically targets TWO INTENTS: 1. Wet-Salt 2. Bad Mineralization This is to say...….. it does NOT target mega-trashy areas...… does NOT target carpets of nails. * NOT for beginners/novice. Targeted for seasoned detectorists. * IP-68 * 11" x 8" DD open coil (hydrodynamic) * Electronics designed TO/FOR the coil. ((( If you want to change coils..... you must change the electronics. This is a very specific/discrete platform. ))) * Weight/Ergonomics: Very similar to F75/EQX/T2 * One rechargeable battery. 1-1/3 length of a C-Cell. Diameter of a C-Cell. 6000mAh 3.7V. This is a 'off the shelf'......easy to access/buy......and YOU can change it... in about 40-seconds. (Under the armcup). * Full VDI ID ….. with a 60-point span. * A very real/correct All-Metal Mode. Disc Mode. ID Mode. * Iron span range is: -30 to 0. And for a very specific/discrete electronic platform rationale/justification. You DON'T want this changed. * Non-Ferrous span range is: 0-30. * In certain modes..... very responsive to high conductors. * Inches deeper than Excal/CZ/Sov for coins and gold rings..... in a wet-salt environment. ((( Almost exactly parallels the performance of my 'tuned/tweaked' AquaStar-II..... in the wet-salt. . . . . but. . . . . with FULL ID capabilities. ))) Resonant (great) for tiny gold rings, small, medium and large gold rings. This is where the depth advancements have taken place. * One of the paradigm-shifts: Ground Balance the unit in the dry sand FIRST. ((( And in a different fashion: Hold coil about 10" above the ground. Press and hold GB button. Lower the coil to about 1" off of ground. Release GB button. DONE. ))) Then...…… walk down to the wet-salt. . . and manually zeroize your local wet-salt content/volume. Now the detector … no longer even sees the wet-salt. It is not 'canceled'. It is not phase-shifted out. It is not Ground Balanced out. The high conductivity of the wet-salt is no longer seen. This is a fairly large dramatic departure from all other detectors. First time in history. A paradigm-shift. * This unit targets beach hunters.... and relic hunters in bad dirt. This unit loses depth/performance in bad dirt …but at a SLOWER rate than other units. It 'holds on' to good target ID's at deeper depths.... in bad dirt..... at a better depth/ID rate than other units. * Trying to keep the cost below the CTX-3030 MSRP. If we don't market/advertise it..... the cost may be around $1600..... or slightly lower. The intent may be to sell the unit on this web-site (forum) only/exclusively. That way..... we can circumvent advertisement costs (which can be very expensive). * For the most-part: K.I.S.S. theory has been employed. * Heavy gauge carbon fiber. More details to follow...… possibly. http://www.dankowskidetectors.com/discussions/read.php?2,152652,152652#msg-152652 Sun, 19 Apr 2026 05:30:34 +0000 Phorum 5.2.23 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188545#msg-188545 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188545#msg-188545 NASA-Tom Thomas Dankowski Metal Detecting Forum Wed, 15 Nov 2023 12:00:46 +0000 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188542#msg-188542 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188542#msg-188542 Shelton Thomas Dankowski Metal Detecting Forum Tue, 14 Nov 2023 16:07:25 +0000 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188541#msg-188541 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188541#msg-188541 Shelton Thomas Dankowski Metal Detecting Forum Tue, 14 Nov 2023 15:52:45 +0000 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188533#msg-188533 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188533#msg-188533 JCR Thomas Dankowski Metal Detecting Forum Mon, 13 Nov 2023 15:52:08 +0000 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188526#msg-188526 http://www.dankowskidetectors.com/discussions/read.php?2,152652,188526#msg-188526 Dimitar DOES have: good ears!

Agree with the need for better ID. But........... two things =
1. Even just a 10% increase in ID accuracy....... over the existing platform......... would be a formidable gain. As of right now...... ID accuracy is approx 70%. If it could be jumped up to 80%.,.,.,. this would be formidable.
2. The Tarsacci's specific electronic architect (ID methodology) of the Operating System........ does not (can not....... to the best of my limited knowledge) lend itself to any formidable increase of ID accuracy.

There's no doubt that the machine has some unique capabilities, but the lack of VDI accuracy in particular, in my dirt, rendered it largely unusable for my type of detecting. However, building upon what is there, with some form of greatly improved VDI/ID capability, would CERTAINLY pique my interest...

Any news?

The Tarsacci may be getting old; yet, it is not outdated. It is still (by far)...... one of the best (if not: the best) units for mineralized dirt hunting. I know Dimitar is always working on new stuff. The company is (quietly) doing well.

Interesting, I talked to one of the power company technicians yesterday and he stated the power lines I mentioned above were in fact 3 phase.
Now instead of 1 source of EMI I 3 to contend with, each peaking at a different moment in time.]]> markg Thomas Dankowski Metal Detecting Forum Wed, 21 Jun 2023 12:08:58 +0000 http://www.dankowskidetectors.com/discussions/read.php?2,152652,187809#msg-187809 http://www.dankowskidetectors.com/discussions/read.php?2,152652,187809#msg-187809 And....... if the EQX is ID'ing a 4" dime as 'iron'....... that's high-mineralization.

Adjusted threshold and nothing helped.
SB through the entire range of options, could never get a quiet setting, nothing helped.
Turned on Black sand, no help there.
Screen displayed random numbers, EMI at the worse of any machine I've ever had.
Adjusted the GB up and down, no good.
Now I could reduce the sensitivity to 2 and this helped but the machine couldn't not detect a 4" dime in the ground. No joys here.
Increased the sens back to 5 and could only randomly get an audio on the 4" dime.
This is my 3rd trip to this site in and attempt to hunt. Most successful was the TDI SL with the 7 1/2" coil.
This is the area I've always talked about, being the bad, coke waste school.
Big difference between silent and auditable EMI. EMI completely shuts down this machine.

I am transitioning through a painful learning-curve with Manticore....... by dropping iron breakpoint (Ferrous Limits - Upper & Ferrous Limits - Lower) down to 3 & 3. This is a psychotic level to hunt with...... in carpets of nails; yet, ..... is proving to be very rewarding. I am just simply wondering when I will hit the "point-of-no-return" (..... the law of diminishing returns) on: LOWEST breakpoint setting...........VS..........additional unmasking attributes.
I remember a couple of years ago...... TRYING to employ: Upper = 5 and Lower = 4..............,,,,,,,,,,,,,,...............and completely having the INABILITY to handle those settings. A couple of years later....... I am employing: Upper = 3 and Lower = 3! This POSITIVELY validates = It IS a genuine LEARNING-CURVE!!! skillset. The detector has NOT changed.,.,.,.,.,., but/rather....... the 'skillset' (and tolerance level) of the operator HAS changed.

Yes....... coming out of the SALT Mode on Tarsacci .... DOES allow it to be more sensitive to small and/or low conductors......... (of which: most jewelry conductively resides). You CAN use SALT Mode to practically see through some chewing gum foil.....and detect a silver dime well beneath the foil !!! Use wisely!!!

((( If you are use to hunting in bad dirt........ chances are = you'll catch-on at a MUCH faster rate ))).

This makes it very easy to change frequency on the fly over a suspect target or to deal with the ebb & flow of a location's EMI. Of course you have to invest the time to set up each one for the site but it is worth the trouble. It is also very nice to be able to shut the unit down to take a break and the be able to fire it back up and immediately start hunting again.
Salt Balance not only negates small Al & foil, it also helps with conductive rusty ground. A proper Salt Balance will give you the best & most stable TID.
Keep hunting & posting.

I went through these frequencies multiple times and each carries the GB of the prior frequency settings.
Not a problem for me.
This unit has a revision of 1 "R1", no idea how many revisions there might be.
Thought I would hunt a while without SB enabled and noticed I was digging a lot more pieces of foil that gave a good tone. Enabling SB and these deep trashy items would break up after a few coils sweeps. Nice.
Starting to hear the difference in iron false tones. Nice.
Even if you get a good tone one way, 2-3 more sweeps over the target reveals its true nature.


One thing for sure, if the ground has ever been moved, the GB will be a lot less than compacted dirt "what we call field dirt in Virginia"
