I can attest/validate this video. Good capture.
I merely wish that he would have used a bit higher Sens whilst using the M8 coil. I believe he could have used a Sens of 27.....and ...... with a steady hand/sweep..... would have acquired better (and still 'stable') results. I use Sens 30 with M8 coil....... but I DO like the unit a little crackly/chatty!

His sand appears to be fairly pure silica sand..... with minimal minerals. (Only alkali).

Hi Mr Danksowki…greetings, hope you are well.

You may be wondering why the video was done.
I’ll explain. Some folks have been saying PI units deeper overall wet salt sand as well as in the salt water, a blanket statement of sorts. If we dial the clock back to when Excalibur 2 released. This blanket statement then may have been true imo. But along comes Equinox, Deus 2, and the mighty Manticore. These units likely make the blanket statement false. Yet even seeing Calabsh show 2 PI models on NC salt beach wet salt sand what is seen in the video performed in Australia are similar results.
One gent even said Florida beaches PI deeper than MF.
So, you live in Florida I believe.
If the gent in Australia came to a beach near you and done same test in wet salt sand, what would be the results please? Best guess…
You see pi units many don’t have external speakers hence not a lot of videos on YouTube showing comparisons of MF vs PI on beaches.
Calabash has remote microphones. He uses and places in pi unit headphones cups to show folks what is going on.
This which is deeper PI or MF has sparked some debate and yes there are some who may not even believe the gent in Australia results.
Nor do they believe Calabash’s results he got on NC beach.

Any info you can supply would be helpful for the detecting community.

PS
The Pi unit called Garrett Axiom wearing 11x13” DD coil gets its turn in the barrel next on NC beach against the Manticore soon.
I’ll post this video link here so folks can see. I don’t know what the results will be.

This video shows nicely... how the Manticore ... identifies the target by changing the target depth. -/5cent nickel/..
at 18 inches the signal is almost without VDI but it is nice to see,, where the target signal is located in the Iron limit graph..

The terrain of this salty, wet, sandy beach seems to be low mineralized because the range of the VLF detector /Manticore/ is really good..

Here it must be said that modern multifrequency detectors on programs with salt elimination.. really prove to give good depth results in detection.. in conductive terrain,,,

I know that there are specific conductive terrains where Manticore does not excel especially on certain targets.. which my colleagues and I have tested several times..

From my point of view, the PI detector does not have to stand out here because the terrain of the beach is low mineralized, and reasonably salty.., so the best features of the Pi detector /detection in strong mineralization/ do not have to be especially effective here...
The advantage of the PI is shows itself in more demanding terrain..

As for the PI Axiom, it will be interesting to see a test with a 13 DD coil which corresponds in size to the 12x10 DD coil of my PI ATX..

[NASA-Tom]

Speaking specifically for all of Florida (and Georgia & South Carolina) beaches......... I do not believe there is a PI that will out-perform the Manticore ... in the wet-salt..... on the beach. But....... keep it: apples-to-apples...as far as coil-size goes. Yes..... a 15" coil on a PI may beat/trump the Manticore with the 8" coil.

Now........ if you have mineralization....... (say) 3-bar or 4-bar (Fe3O4 bargraph) mineralization.......... in a wet-salt environment..........,,,,,,,,,.......... THIS is where the tables start to turn.......and a PI may start to outperform a SMF/VLF unit. A good example is: Northern California beaches...whereby.... there's a fair amount of black/magnetic sand. This is where a PI will win.....especially in the depth department....(((yet: fail..... in the ID department))). In cases like this...... it's Tarsacci time!

Basically you don't need a P.I. till you do.

And you'll know when you do.

Wet salt silica sand like southern eastern coast stick with multi.

Wet salt black sand grab a P.I. (Hawaii)

Iron rich ore and or black sand shore deposits grab a P.I.

Move inland to high F.E bar soil like 6/7/8 grab a P.I. especially as you hit the 8 FE bar.

There's even some inland lakes in the U.S. that's P.I. will be optimal.some lake shores are magnetite volcanic deposits.

I would surmise the great salt lake is a tough one to hunt the beaches super salinity and lots of minerals.
Used to be quite the tourist destination in early 20th century.

That is a very accurate observation Keith.... 6-7 Bar Fe3O4 is somewhere at the level of 4-5% magnetite..in the field...and here a very good VLF detector /suitable for magnetic field/ can still be great with a PI Detector..where the detection limit is 8" per 1 gram of 24K gold..
...But on magnetic mineralization with a strength of 8 bar Fe3O4 and more... it is already the detection domain of a PI detector..
Another advantage of a PI detector is, for example, the ability to detect very small targets 0.1 gram of gold under ironstone...
A modern VFL detector can detect a target under ironstone but must deal with a significantly larger target at the level of around 0.4-0.5 grams..
