Funfinder look at this:

Not sure what to make of it.

[Funfinder]

Crazy stuff! Reminds me on those hiking-poles with inbuilt magnetometer at the lower end.

But one thing is remaining "invisible" while detecting and the other digging out the stuff.
If you have to dig out the stuff after midnight you also can detected it at this time.

While www.metaldetector.com is a really good MD-shop I still can't say what I should think about this drs 3D vest.
For me this looks like a wireless magnetometer setup but they write it can detect if its noble metal or iron.

Though the screen-images doesn't look real high definition concerning the detection-resolution -
seems you will just get some approximate field values of each 1-2meters with very "blurry" imaging.

My personal opinion and suggestion:
Write metaldetector.com a mail and ask them or the company directly for further details first.
Because this also depends at what area you wanna prospect and how large the finds are.

It may work great at plain fields with low mineralization like in arabic countries or at battlefields over Europe
but in mountain-regions or at the jungle I'm not that shure.
And of course such a special detector will not replace a real metal-detector plus sensitive pinpointer.

And if they write already it works with smartphone android this reminds me pretty much at a piece of
software like this here, which is magnetometer based, too:
https://play.google.com/store/apps/d...mobyle3d&hl=en
(check the Magnetometers forum area for more info)
Just for information you can take a short look at: http://www.okmmetaldetectors.com/
because they offer other magnetometer based detectors there, but they also sell Long Range Locators
and their reputation is very bad all over the MD world! Search this and the LRL forum for more infos about OKM.
For me this drs 3d looks pretty the same as those extremly overpriced OKM magnetometer or LRL devices.


Of course usual magnetometers or gradiometers are working, but they need alot experience and a good knowledge
of interpreting the output images correctly, otherwise you will end up digging deep holes for nothing.

So the best method would be to get detailed info first and test such stuff personally - at a location that is
similar to those for what the detector would be intended finally.

btw. what you did not asked for so far are movable GPRs that work on a 2 antenna and 30-500 MHz technology.
Costs are 10.000 bucks upwards, detection results: very questionable!
I saw already some docus with nice display "radar" output (alot zig-zag lines or hard to recognise ground patterns)
but they do not work everywhere and they really can produce crazy failure-signals, too.

You may be lucky and find a really good working one but this could easily costs 30.000 bucks.
Those detectors are used by professional archaeologists to scan the soil for hidden walls or culture-layers etc.
Using them of course also needs alot experience and you have to scan the area by grid-patterns first to receive
a complete data-image of the whole area in the end.
Here you can find some products overview: http://www.geophysical.com/products.htm
If you have the money to buy such device testing it before is an absolutly must because there are so
many different types that you have to be shure what kind of output it produces at certain locations.
And too deep signals are not always a benefit - they can lead pretty fast to 10meter deep empty holes.

https://play.google.com/store/apps/d...mobyle3d&hl=en

This demo app does not appear to exist in the Google Play Store, although the other three [non-free] OKM apps at the bottom of your link are present.

[Funfinder]

After 1h of search it seems they have removed that demo app from the whole internet ....

Perhaps the smartphone magnetometers meanwhile are even better than those of their overpriced rover uc sticks
so they became afraid of losing money with their cheap demo toy in combination with newer phones.

But who cares - the german law will smoke OKM out soon, these "bionicized" LRL-fantasts ...

detecting the smallest possible finds with 32cm coil - test

Today I got some real interesting results - finding out what is the smallest stuff the DeepHunter is able to detect.

That ultra-thin and perhaps 0,001 gram lightweight flitter of alu-foil was detectable nearby TV and computer
from around 2,5cm (1 inch) at all-metal and sensitivity 8,5, the same with the 1,5mm small compact tin-ball.
The coil has to be swept pretty fast at ca. each 25cm x 25cm spots for best ultra-small results.

For a 27x32cm coil this is absolutly amazing, because this is not a super small 10cm goldnuggets coil but one
that also is able to find beer-caps at ca. 50cm and large stuff at super depth where any 10cm coil fails completly!

And because of the high electro-smog immunity it doesn't matter if the site is in the middle of the living-room
or if its outside in the wilderness. Of course a very good pinpointer is needed to locate all the super small stuff.

Good luck ...


PS: Meanwhile there exists a second detector with the name Deep Hunter
(Golden Mask - Deep Hunter) so don't get confused:
https://www.youtube.com/watch?v=ilzB...yK7w10u8VXYdLg
It works with pulse induction, comes from Bulgaria and the depth seems to be very good, too.
http://www.shop.imperio.bg/golden-ma...hunter-pulse-1

Of course it has not all the many features as the original real DeepHunter but walking around
with a large but lightweight 55cm coil plus hang over the chest P.I. unit can bring good results.

The Makro Detector DeepHunter really finally would need a very lightweight 65cm motion coil
for the easy ultra-depth experience! Perhaps with 2 holders and 2 armrests to hold and sweep it!

[Funfinder]

Funfinder what about the pulse units such as the Lorenz Deepmax Z1 and the Deep Tech Pioneer 4500. From the Youtube videos they look like they go very deep and are great in mineralized soil. What is you opinion about PIs? Thanks.

Yesterday I saw the docu "The Curse Of Oak Island" (from 2014) where they also used the Lorenz Deepmax
and it failed BIG-TIME with the BIG 2m coil!
Check out episode 4 and 5.
But this happens if amateurs use profi-equipment and if they believe in crap like curses and demons, omens and dreams!
They also fear about that first a 7th person must die on oak-island until the treasure (or the "secret") will be revealed.

The data-logging output was full of red "noble-metal" spikes but in the end they found nothing at this swamp-region!

How simple can it be? Use a good normal metal-detector and reduce sensitivity or even just use a high sensitive pinpointer
and you know if the target is real, you even know it if the target is a 2mm metal-shard with a modified Garrett Pro-Pointer!

Personally I assume that the camera-guys moved too close to the electronic-box or the electronic-box was very near
the (btw. very unstable looking) 2m frame (this is stupid anyway: they claim the coil is 10m deep but the coil cable is just
2m long - so why not detecting the electronic box directly?) so thats the way they got their "fantastic" signals all over the area!

landman, as I told you already - be careful with those P.I.s - you don't wanna spent more money to dig huge holes for nothing
compared with the costs of the MD itself!

[landman]

Funfinder, I just purchased a used Nokta Goldengate 3D detector. Will be experimenting with it soon.

[Funfinder]

Not the best idea in my opinion, but mainly because of the huge weight -
I've mentioned the weight-issue already many times.

Well, heres a short overview:
http://www.metaldetectingworld.com/4...oldengate.html

The weight is already with standard coil but without the batteries 2,5kg
so it will have with accu-pack and 32x40cm coil perhaps ca. 3,5kg.

For longer hunts you absolutly need the orginal Nokta accessories
that come with this detector: the bungee-weight-reduction-carrying-harness.

For serious usage you also should get a backup battery-pack.
And also the standard accu-pack must be still fit enough -
would be no good if its already from 2011 and has lost half the power meanwhile.



Personally I have never worked with the Golden Gate but it seems to be
pretty similar to the Golden King, it just can't be used with the 1m coil.

Because of the weight it will be hard checking-out huge areas to find
brand new treasure-spots but if you know already about promising places
and with some experience you will detect pretty deep and interesting stuff.

Buying this detector used was a clever move because that way you can
test out and experiment how the non-motion technology exactly works
and if also everything else really fits your needs.

Main drawbacks: evtl. too old used batteries, weight, no XXL coils available
The max. depth is limited by the largest coil with 32x40cm (15.7'').

hi landman,

if you want some info about the bungee-vest, below there's something attached.

btw. I made some tests with the (see also below) T44, T100 (both non-motion) and C47 coils.

So far the motion-coils for the CoinFinder CF77 don't offer the 32-35cm size -
so at the moment the super standard C32 coil (26x32cm) is another pro argument for the DeepHunter.


Next I calculated the diameter of one single part of the T44 nonmotion coil - it has 44+16+44+16cm
This is 1meter20. So the total wire-lenght if the complete DD coil would have just two single turns is 2m40.

This is important if we now compare the depth of the DeepHunter T44 coil (44cm x 32cm nonmotion)
with those of the largest from the Golden Gate which is nonmotion too, but smaller and more eliptical.

Compared with the Jeohunter the depth of the Golden Gate may be reduces about 10-15% because of
the smaller coil size and compared with the DeepHunter about 15-20% because of its new depth-improvement.

But this is not that much, a 10x10cm alufoil-plate will be still found at ca. 70cm with the Golden Gate.

btw. I have tested it - the DeepHunter with C47 (39x47cm) motion-coil also is able to detect a
10x10cm alufoil-plate at 85cm in air which is the same distance as with the nonmotion T44 coil.

The T100 coil found the 10cm alufoil-square even at 90cm while it detected a 20cm alu-square from 1m15.
The depth analyses was very exact. Those tests were made in the living-room with all kind of metal-stuff
nearby. This is absolutly no problem for such detector. Sensitivity-setting: 9 (one step below the highest).

Interesting also is the oscilloscope-curve:
For the 1m coil T100 the 20x20cm alufoil gives a very weak signal starting at 1meter20 while the
100% power-peak shown on the screen already is reached if the foil is still 75cm away from the coil!

This demonstrates how sensitive the DeepHunter is, because the closer 2/3 of the whole detection distance
and ability already is far stronger and over the shown 100% limit.


The main advantage of the nonmotion-technology absolutly is its depth!
Because of the static and not "blurred" energy-values it provides, detection of stuff beyond 1meter
depth is alot better reachable with a non-motion MD, compared with motion-detector and same coil size.

I have to test this again with different conditions but it seems, that someone has to sweep its
45cm motion coil really very fast to receive a signal from a 25cm pan beyond 1 meter distance.
With nonmotion this is absolutly no problem, a 45cm coil even will find that pan at 1meter 25.



So landman, for the moment and if you can deal with the weight and the percentage of
depth-loss compared with the DeepHunter, you will be still able to reach pretty nice targets.
You will see it was OK that you got a detector with non-motion technology
which also has reliable discrimination and can find cavity and if you have found out all
the advantages first hand, you still can go for the best available equipment in this area.


Important for your tests and experiments will be in the beginning that you start with
lower sensitivity, learning how to recognize and distinct the real and repeatable signals.
You may retry and use the reset-button in the beginning until you have enough practise.

After some time you can raise the sensitivity and the search-speed for geting closer
and closer to the maximum possible depths. You also can experiment with layers
of mineralized bricks and with cavity and you will see the huge difference compared
with motion-detectors! Many of them have no chance at all to detect anything below some bricks.

Have a good time with your first tests and good luck.

I was under the impression that the Blisstool owner is the greatest detecting writer out there. BUT! REALLY! Only now I see why was the Pulitzer prize invented.
You still got to catch up with the million videos on the Internet.
I wonder who's going to win this one...

[landman]

Hi Funfinder. Buying the Goldengate was just a cheaper way of getting into the 3D detector game. it's my new toy and I'm excited to see what it can do. If it surprises me and I find a good application for it that will be a bonus. I'm waiting till the summer of 2015 for the new Nokta. If that looks as good as they are alluding to then that will be my next purchase, otherwise I'll join you with a deephunter. See attached.

Look at Nexus, seems he needs some attention by freaking around and brabbling stupid sh*t like a little kid!
Offtopic, next please.

Hi landman,

thank you for the depth jpg - I assume it shows the 40cm coil values and with 120cm for a 20x20cm brass plate in air
it may detect it at medium mineralized soil at 90-95cm but at sensitivity 10, so you really need a good practise first
because usually, depending how high mineralized is the soil, searching at sens. 8 is the intermediate standard.

btw. from my point of view it's not about the 3D stuff and all the additional gimmicks - what counts is depth, quality
and reliability. Thats why I prefer Makro-Detector over Nokta, because The Jeohunter and meanwhile the DeepHunter
focuses on what really counts and don't wants to create some kind of "Multi-Apps Computer-Metal-Detector" with all
kind of additional stuff. Depth analyses and visual 3D images are great but they only count for the real deep hunting.

If ca. 85% of all finds are not that special deep, you will proceed much faster forward if you don't bother
with scanning and analyzing it at all, just dig it out within a few seconds or minutes and save your time.

Or even better - clear the area with a Garrett Ace first until all the surface near stuff has been removed
and afterwards look with the professional equipment for the real deep stuff. The larger the coil, the bigger
and deeper treasures you will find anyway. And often this is absolutly true: The deeper, the more rare it is!

Infact its not the "3D detector game", its the ultra deep detector game including using large coils and
of course this only is useful at real promising and "rich! locations. And by the way those non-motion detectors
simply are super-immune against electro-smog, though I only can speak for the Jeohunter and DeepHunter
but I guess the Nokta may be pretty the same if it comes to that. If there is an antique roman street directly
nearby a town or highway with electricty lines etc. only the best motion-detectors still offers an useful depth.
And of course thats also the reason why are nonmotion deepdetectors much better penetrating mineralized soil.
They use a very powerful but stable EM-field which doesn't gets blurred away by the motion-circuit.

Btw. with some good bungee-cords from a gym or sports-shop you can built your own weight-reducing-vest,
just be careful that the material is strong, thick and secure enough so there can't occure any health-problems.

And also important: Good luck for finding some great treasure-locations where your detector really can show
its full power because this is not for gold-nuggets but for the real deep and so far undetectable special stuff!

[landman]

Two questions:
1.) If I were to clear the area out first as a first step with a Ace 250 what size coil? Their largest?
And would I detect in All metal digging everything? or just non ferrous?

2.) If I was to hunt specifically in the Andes mountains and needed good mineralization handeling, good depth
depth and a good size loop, And since I'd be backpacking in which means it would have to be light.
I've got it down to these detectors to go in with that in mind. And may I add it would be to
explore each area to see the potential of several sites and then to bring bigger heavier deeper equipment in at a later date.
So far I've narrowed it down to:
a.) Bliss tool V with the 15" coil
b.) Aka T-72 http://www.aka-detectors.com/metal-detectors/t72/
with the 15" coil.

[landman]

PS: What do you think about this? My understanding a new Manta V4 is replacing the V3 soon.
