Beach trip with the Tarsacci

[Mark-VA]

The guy that loaned me the Tarsacci has given his approval to take the machine to the beach this fall. Really looking forward to seeing if it really and truly outperforms in that environment or not.
So far:
In low mineral ground detecting there is no advantage over either the F75 or the Equinox 800.
Could elaborate for hours on this one.
Heavy iron sites is no advantage over the F75 or the Equinox 800.
Many hours of comparisons here too.
The super bad ground sites (coal waste, slack) has proved to be a very difficult task since the Tarsacci is extremely affected to EMI. Solutions were to turn the sensitivity to 4 which make it perform almost exactly like the Equinox 800. And again elaboration could continue for some time.
Well anyway, one of the guys that also has the Tarsacci told me, in the wet salt environment the Tarsacci will excel the Equinox 800 and the Deus 2.

Probably not.
When evaluating and comparing detectors; one very important thing is persistently missed, a decisive factor, I would say.
And that is the impermanence, the variability of the conditions in the soil/sand itself, during the day, often within the hour.
I have been pointing out for years, and no one pays attention (doesn't understand) to the strong influence of the sun, magnetic storms and the planet's magnetic field.
It is not a final process. It is a very dynamic process that does not begin and does not end; it's already going on constantly.
Sometimes there are huge changes during the whole day and sometimes during an hour.
Sometimes the detector behaves the same in one and the same place, and sometimes it behaves completely differently.
This is very easy to check and test. Bury the coin to a depth that is at the limit of detection, but so that the detector clearly "sees" the coin at that moment.
Remember the settings on the detector. And return to that place several times during the day and several times during the month, year.
Take a notebook and record the subtle changes.
After 20.50... 100 records; you will clearly notice a "curve" in the changes and the "extremes" on the curve will not be as subtle as they seem at first.
That's why all deliberate detector tests are very vague and don't give permanent results.
That's why all this is a "game without limits".
That's why we've been dealing with this on the forum for almost 20 years.
The same stories.
And a bunch of new models.
Every new detector "brings something new"... and in reality it is not like that.
People do not understand the essence of the problem.
They will go into great detail about everything on those topics... but they will always skip the essence.
Making and dealing with magnetometers "opened my eyes" and helped me understand a lot about ordinary detectors.
With an ordinary metal detector, you cannot see the magnetic field and its behavior.
With a good magnetometer you literally "see" the magnetic field and its behavior.
I just remember Aziz trying to write magnetic field visualization software.
Ha, ha, ha... a momentary "flash" while I was writing this.
...
Off topic... but lately I've been thinking more and more that it's about time I made some Helmholtz coils for further experiments on these topics.
The problem is because it would have to be large coils with a longer distance and strong enough to produce a constant magnetic field at that distance.
And in such conditions, the metal detector test would be quite objective and accurate.
The strength of the magnetic field between the coils must be sufficient to cancel external influences and weak enough not to disturb the normal operation of the detector.
A serious task.
That's why I put it off for a long time.
(There is less and less money in this business, almost no money at all anymore, so that is the reason why I gave up a lot of things, one life is too short for all ideas)

Yes, I have verified for years.... in my test field with the pulse detector that I manufacture, I have samples in the ground from 40 centimeters to 3 meters. there are days that I perfectly detect the sample at, for example, 1 meter moving the antenna north-south but moving the antena east-west i detected lower... and there are other days that is the opposite... it would be magnetism, the moon, etc? I have checked this phenomenon al 100%...the same with a Barnes magnetometer.

Very interesting. A lot to think about. Would explain why some days I have one dime in my test garden that just doesn't want to be found. Then a few days later, a nice clear repeatable signal.

Well the beach trip was a flop. Top Sail had dredged sand and filled the beach up. What I could tell may be 5-6 feet above what may have been normal. Well beyond the detection depth of any detector. Got to send Keith the detector back this week. It was very nice of the guy to loan it to me for over 2 months.

Some time ago I stumbled upon a video on YouTube in which David Adair talks about a lot of interesting things on different topics.
At one point, he also mentions the "doom of the world" that was supposed to happen in 2012.
We are all already familiar with the theories about that.
Although it is difficult to verify; I tend to believe everything he says about the case.
The part that is interesting for this topic on the forum is precisely solar magnetic storms.
This phenomenon is real, constant and represents a kind of "normality" on the scale of the universe.
The impact on planet earth is unquestionable and even easy to see and measure, even in amateur conditions.
In 2012, three strong solar magnetic storms headed directly for planet earth.
The calculations were that if they hit a planet; that within 6 months life on the planet will cease to exist in the forms known so far.
And those three magnetic storms are only slightly stronger on the scale than the "ordinary" ones that happen constantly.
It is easy to conclude that this is a factor that for some reason we have excluded from the "equation" when we talk about metal detectors.
And that is, in my humble opinion; the most important factor that directly affects some properties of soil as a medium that is the main obstacle between the detector coil and the target.
Each of us noticed these radical changes in just one day. But few have fully explored what it is all about.
That's why I often advocate the use of a magnetometer, not so much as a direct detecting tool; as much as a type of "measuring instrument" that will directly indicate these changes.

[Mark-VA]

Interesting.

[ivconic]

Two hours of very interesting stuff. You will have to search through; to find what I mentioned.
Anyway it will be very interesting for you to watch it.

During all-day searching with detectors, many have noticed sudden changes in the detector's behavior when moving from a sunlit surface to a shaded surface,
usually early in the morning or late in the afternoon.
The detector either goes into chattering or noticeably quieter behavior.
Everyone will associate it immediately with moisture in the soil.
But there was no time for the humidity to change so drastically, because the sun had just disappeared from the, now, shady parts of the surface.
So what is at stake?
This is most easily noticed on the spiky hills, when you walk in the style of peeling an orange.
Perhaps many of you don't have chances to visit such sites, but here in the Balkans, almost all late Roman sites are like this.
Some would say "Byzantine" sites.
These were mostly fortifications on deliberately chosen hills.
And the sun "moves fastest" in such places.
During the same day, parts of the hill are strongly affected by the sun and minutes later/earlier they are completely in the shade.
There was simply no time for the humidity to increase or decrease.
Mineralization remained the same, moisture remained the same, what changed?
That's my point.

With more hours spent on a difficult UK beach than most, I can tell you, the Tarsacci rules on my wet beach,

I started life with a Minelab Sov Xs, then a PI c scope 4pi, (always keeping my Sov to hand)
ive had the D2, the equinox, the legend, the beach hunter TDI, and now a manticore, and a few more that have slipped my mind, I was one of the first people in the uk to get a Tarsacci.

NOTHING put more finds in my pouch than the Tarascci,

on dry land, I would say the D2 is up there as the tops, but on the beach, I did not rate the D2

I have detected the same beach for over 30 years,

now get this, not only have I detected this same beach for 30 years, but I detect this beach 99% of the time, I know my beach like the back of my hand, and its a tough beach to get right.

The manticore is a close second to the Tarsacci, but the manticore STILL has issues regarding iron.

Minelab are barking up the wrong tree, with the manticore and its Iron falsing, I should really start a new topic on about this, but in short, (on the beach at least) the Manticore does NOT false on iron per say, but it gives a iron tone to iron that's not there)

[Mark-VA]

I talked to a man involved with the Tarsacci since the release and he stated the coil was most likely faulty, which not only explained the erratic behavior, loss of detecting depth extreme EMI and many other issues. But I had to return the detector, so I guess I'll never know for sure. I guess the best detector I have for my extreme sites is still the TDI SL. I'm sure glad I didn't sell it.
Oh did a few evaluative test lately with both the F75 and the Deus 2, both indicated maximum ground mineralization at these sites. Explains a lot. Most targets deeper that 4" either gives an iron grunt or just crackling sound but the TDI signals there is something there.

All this really makes me want to try a different Tarsacci. Tom Dankowski has kind of stated the same thing as you. Even the owner stated it should do well in the heavy coke areas but the EMI had me shut down.
Thanks for your post.

Keep in mind, on a easy clean beach you won't see the benefits off a tarsacci.

It's only on beaches that would normally be classed as difficult beaches

And were talking in the general term off mineralisation

On heavy iron (which my beach also has when the sand depth is low) I would favour the manticore)

Put it this way,

My tarsacci is my go to detector (for my beach) 95% of the time

I cant say enough, my beach

If your beach is a clean yellow sand with little mineralisation, your not going to see many benefits
