There is only one detector better than Deus - it is Deus with larger coil!

DONT START THIS AGAIN

I didn't need to wait long; to get full justifications of my doubts.
And as old member here i feel obligated to "blow a whistle" each time i suspect the problems.
I guess you can't read Russian; neither than i. So i used Chrome and translation to read this:

Here you have some motivation for your tests!

Vast majority of my finds is dating from period of Constantine The Great.
My house is laying on his paths literally.
I've been doing this for 30 years.
I do know about Constantine literally everything, i could write a book.
He is my "neighbor", born 60km away from me.
So i don't really need any motivation.
I only need to wait until October, since than starts my most favorite period of the year for such activities.
Right now, after 3 months of unstoppable heavy raining, last week is very hot and you can't stay longer than 20 minutes outdoor, without fainting and nausea.
So, my motivation will have to wait...
Until than; i flooded myself with mastering the 3D design and 3D printing techniques.
...
About my "most favorite" find of all times; the horseshoe... well!
If i put aside each horseshoe i dug so far; by now i would become world greatest iron tycoon!
I would have my own 100m long yacht and i would cruise around the globe!
Pity... i tossed those each time after the dug.
So, my advice (as an old expert) to a young enthusiast would be: kids; DO collect those horseshoes and DO bring them home!
Pile them and wait. Be patience. Eventually one day; you will earn a fortune from selling that iron!

Try large iron. Say a horseshoe against a cut half. See what you get. I don't have a Deus or Kruzer to try.

But I bet I know the answer.

The best you can do is half the coil diameter.

I have tried a T2, IDX, GM 1+ with both DD and concentric with coils ranging from 5.5" to 12" the answer is always been the same half the coil diameter.

Recovery speed is something else. This governs how fast you can swing and is machine dependent.

Iron separation (masking) is governed by the coil size. Banging a large coil on here in the UK will not make you find more. Our fields are full of bits of plough, horseshoe and so on.

Depth here is not the limiting factor

Perhaps Ivconic can test it cause so far I also have no Kruzer - yet.
I guess the larger iron- and steel-parts always will mess up the discrimination and id-values.

We'd need a MD combined with magnetometer which offers some field-strength analyzer
so the overall find-signal can get compared to find out if there is only the iron
causes the signal or if there is also some non-iron object nearby or below.

Or a metal detector which only can find diamagnetic metal.

https://en.wikipedia.org/wiki/Diamagnetism

Another question is - concerning the wireless XP Deus coils:

If would be already a big improvement if all MD-manufactures would start
to use fiber glass or carbon stems instead of these stupid alu-pipes!

Because if this alu thing already is 30-50cm close to the coil and
the coil shifts into a slightly different angle by touching something -
per instance higher grass or small bushes - this creates already a false signal -
especially if using larger coils.

Iron masking ????

The larger the coil, the higher the masking-effect.

The Kruzer has a very good and fast metal-alloy-objects-distinction
(see test-video - link is at the main Kruzer Thread) but depending
on the iron from low level to steel it always can interfere.

Especially if the iron objects are in between the coil and the deeper good finds
instead of just horizontally on the almost same level nearby.
And very deep or weak non-iron-objects even can show up as iron.

This is fun!
I've been constantly criticized for recommending and glorifying the Deus...
I am not the only one though:

[Funfinder]

I'm guessing that after 5 years a lot people will sell the Kruzer
just because the internal accu is dead...
They better should have used from the outside changeable LiPo cells as in ultra-bright flash-lights.

[ivconic]

[ivconic]

..
One question I asked ca. 5 months ago is still unsolved:
Is it possible to replace the internal LiPo accu?
I'm sure it is somehow but how easy...

It is easier than you can expect.
I did several replacements for customers so far.
In essence it goes like this:

34x28cm is too small anyway. I guess we need the 40cm MARS coil from Ukraine for such test.

Iron masking ????

[Funfinder]

Unfortunately i can't. I sold my 34x28 coil few months ago.
I am now having only 22.5cm coil. The black one from first series.
By the same occasion we had Makro Racer that day in company too.
I pay full respect to that machine in a way how it is made, designed and how it looks and behaves.
But it is not competitive to Deus and Makro Kruzer.
2 days of testing outdoor on the very real field (ancient site); Makro Kruzer outperformed Deus and way over Makro Racer.
Makro Kruzer came with small eliptical coil. And i compared the areas of that coil and my 22.5cm coil from Deus.
Not sure but i got the impression that M.Kruzer coil is covering smaller area, aka is smaller than 22.5cm for Deus.
Maybe this is not right, i can't be sure. It simply looks noticeable smaller.
Yet it is picking deeper targets. Or same targets as Deus but with louder and more clear response.

34x28cm is too small anyway. I guess we need the 40cm MARS coil from Ukraine for such test.

And a 22,5cm coil really is just for smaller stuff - for such a coil any usual coin down to 30cm looks huge!

One question I asked ca. 5 months ago is still unsolved:
Is it possible to replace the internal LiPo accu?
I'm sure it is somehow but how easy...

Anyway: I am happy for you that you have a Kruzer and
I wish you further good success with it. I have 2 Racer with
1 small and 1 large coil and I'm also interested to check
out how good the electro-smog elimination etc. of the Kruzer
works. Perhaps you can test the Kruzer near voltage-lines etc.?

[Funfinder]

btw. Hunters who are searching with small coil don't wanna penetrate!
Compare it with sex: Do you wanna come deep inside or just rub on the surface skin?!

For some of these poor boys of course sweeping detector plus larger coil is too heavy!
They don't have or don't wanna have enough muscles for their often just weekend-short-trips.

But it is pretty stupid to throw away the chance of finding precious deeper stuff just because
of using those small lightweight coils.
Someone can do this at a narrow or limited place which is known for coins or other small stuff
but for sure not on a general useful treasure-hunting basis where you must brute-force hack huge areas!

Sweeping a larger coil is no problem if you can sweep 10min with the left and 10min with the right arm.
Meanwhile the other arm can rest and recover and you are becoming used pretty fast to that method.

In the beginning of hunting at a new site a larger coil is much better anyway
for receiving faster an overview and to get rid of the larger finds which can camouflage the smaller ones.
