Tarsacci technology is fake in this test

[Kemper]

Be careful in believing anything you hear or see about the Tarsacci metal detector. In a test that is being touted at Dankowski forum- https://www.dankowskidetectors.com/d...d.php?2,177181 in reference to a video here - https://www.youtube.com/watch?v=AkDD...ature=emb_logo it is claimed that the Tarsacci has a nice feature in being able to detect a U.S. Quarter covered by a piece of foil. Mr. Dankowski states - " And herein lies the difference between: Evolutionary...?. and REVOLUTIONARY. "

I did the same test with an ACE 250 and it picked up the coin in " coin mode " when covered with foil and did not pick up the foil by itself. Be very careful in what you believe from those touting that Tarsacci.

With the foil over the quarter, what was the resulting target ID? Was it still ID'ed as a quarter?

I'll check to see. I was in " coin mode " and it beeped as normal but I didn't look to see . Does the Tarsacci distinguish between a dime and a quarter ? Would a dime laying flat read the same as a quarter on edge ?

I just checked and the quarter IDs in the lower category such as a penny when covered with foil. I don't know what the Tarsacci registers a penny or dime under the foil as and that wasn't shown in the video. The Tarsacci may have better target ID on coins under foil but I thought the emphasis of the video was that it still picked up the coin. I think that is what people were getting out of the video as one commented - "Outstanding, that Tarsacci really has some secret sauce! I don't even have to try that with my Nox and other detectors to know they'd only see the foil. " Which is not accurate as the the ACE 250 does see not only see the foil.

Practically all modern detectors will see the quarter under the foil even if the foil is disc'd out so, yes, "they'd only see the foil" was wrong. But it will be a composite signal that is somewhere between foil & quarter, and that will largely depend on the detector's frequency. And if you have that composite category disc'd out (like, say, a pulltab) then you would not get a hit on the quarter. The Tarsacci continues to ID the quarter as a quarter and that is what's so different about it.

I just tried this experiment with a US clad quarter and a piece of tin foil approximately 3 times the size of the quarter. With the Equinox 600 the quarter reads 30 and the foil by itself reads 8. With the foil covering the quarter the VDI is 8. With my machine the coin appears to be shielded. Very interesting and I am sure that with different settings on the Equinox the results might vary. I was on Beach 2.

On the ACE 250 it will hit on the quarter even if a pull tab is notched out. It will hit on the quarter as long as a penny signal or higher is still " notched in " I understand now that the Tarsacci will ID correctly on the quarter that is under the foil. I don't see any advantage of that though as one would want to detect any signal at a penny or higher while treasure hunting.

I believe this test was done with a clad ( copper/nickel base ) Quarter. It would be interesting to see the results using silver coinage. If the Tarsacci would hit on a silver dime under the foil and other machines would not then I could see an advantage. I haven't tried a test with silver coinage on my ACE 250 or my Equinox but I'm thinking since an ACE 250 will pick up the clad Quarter it would also pick up a silver dime.

I'm just not seeing where the advantage would be of having a Tarsacci that IDs correctly on higher conductors, because a person would be digging all those high conductors anyway, regardless of how they ID.

The pulltab was an example... ferinstance, if a detector gave a composite response for foil+quarter = pulltab and you had the pulltab notched out, you would not hear the quarter. Your Ace just happens to put the composite response for foil+quarter = cent which would not normally be notched. But if you placed a dime or a cent under the foil, then the Ace's composite response will likely be a pulltab. Silver vs clad makes no difference.

Composite responses are a form of masking. Any time you have 2 targets co-located you get composite response, and that composite response may fool you into thinking it's something entirely different. Ferinstance, a '37D 3-legged Buffalo on top of a '16D Merc will likely ring up as a pulltab. You gonna dig that pulltab? What if you had a detector that instead said, "There's definitely a nickel there." Or definitely a dime. Or, in an ideal world, it said "I see both a nickel and a dime." Would that have value? The Tarsacci is showing some of that ability.

I understand what you are saying but this is all based on separation of signals. For instance you can set the Tarsacci up to reject a pulltab signal next to a dime signal therefore letting you see the dime and not the pulltab. But there are many good targets that would also read the same as a pulltab and you would miss them by rejecting a pulltab signal. I see no technology here that would distinguish a good target from a bad target that both have the same conductivity. The Tarsacci may have the ability to keep you from digging what would normally be a pulltab signal, thus allowing you to miss a good target.

Now you're talking about basic discrimination, a whole different issue than masking.

The Tarsacci is definitely not the same-ol'-same-ol' metal detector technology. It's different, and appears to have some distinct advantages over same-ol'. And from what I see, the vast majority of owners really like it. I give kudos to Mr. Gargov for not only coming up with something new, but also persevering and getting it to market essentially on his own.

Yes,it does seem different and the owners may really like it. Unfortunately I don't think it is going to make anyone a better treasure hunter at this point. A new machine that has a different feature is ideal for someone that enjoys playing with a machine. It won't necessarily help anyone avoid a bad target while allowing them to get a good target. It will only help to let one choose between different, potentially good targets.

Seems to me that target masking would be a significant occurrence in many fields. A dig all policy is not realistic for a lifetime of digging holes unless you intended to subsidise your medical expenses by selling scrap iron.
Maybe Gargov's work allows for a significant advantage in scraping through those trash infested fields.

It appears the people who have actually used a Tarsacci disagree. There is an age-old solution to your conundrum: don't buy one.

No.you don't have to dig scrap iron. The video that was referenced here only dealt with targets that had the potential of being good targets. Many good targets fall into the same range as pulltabs.

i don't have a conundrum. I haven't seen anyone say or show that they have become a better treasure hunter with a Tarsacci. I have seen where people are excited to have a new feature to play with.
