Jeohunter - Visual Ground Scanner

[Qiaozhi]

A warning to anyone searching for reviews of the Jeohunter. There are a number of websites that show up in a Google search which will take you to spam attack sites. For example, one of them warns you that your system is infected, and then pretends to do a system scan. The scan shows numerous trojans and worms, and asks you to click on a link to remove the infection. Another one shrinks your browser window to postage stamp size and then claims your computer is infected. As far as I could see (amongst the spam) there are no reviews of the Jeohunter, apart from those issued by resellers.

If you must search, then make sure your anti-virus is uptodate, or you are using Linux.

Hi RMILLER66,

Shure you can search on the beach because it even detects an 18cm Axe below 40cm of high mineralized brick-stones.

But if you want to search for jewellery, coins or rings better take a detector with smaller coil. You can find rings and coins with the Jeohunter but therefore you must search at 90-100% sensitivity, slowly and they shouldn't be buried too deep.

Perhaps you like to search for tresure-chests, old pirate stuff or bigger metal objects from ships or boats you can search through a large beach area in no time and you can impress the bikini-girls if there are any with your big ehm detector!

btw. look what I've also found 2weeks ago in the middle of the woods: a smiling sun!

Let us share our findings of jeohunter

Hi all,

I am from belgium and hopefully i will rceive my jeohunter tomorrow.

I want to thank Funfinder in the first place for his immense effort to share his experiences with his device with us, respect!

I hope all jeohunter searchers can share info on the device so we can all learn from it, as this device has superb qualities.

Keep up the good work!

jeohunter a stupid toy that I had not know why so many boast when and I know it's none of that even 50% truth. sensitivity after passing the 60% considered ground balance (just to throw on the screen of the device)

Thanks for the reply back.
But this machine advertises 6-8 meters with the small coil and that it will pick up a single coin.
I'm looking for a machine that will go around 6 feet deep in sand to pick up rings etc that other machines can't touch.
I'm only looking for 2 meters.
And the machine advertises to tell you what kind of metal it is.
I'm a bodybuilder so the heavier the better for me but it sounds to me that this machine is just another false advertised Knokta goldking?
The company advertises 80 feet and I'm only looking for 6 and your more or less saying that 6 feet isn't realistic on the beach?
And their ad shows a guy detecting on the beach.
If I've missed something please let me know as this would be the ideal machine for me if it did as advertised.

Thanks,

JP

@ Bunne
I wish you good success with your new Jeohunter and you're welcome to tell everyone here your own experiences. Otherwise some guys here never understand!

Tips for your first search-sessions:
Wear shoes without metalcaps, try sensitivity 80%, changing hands for sweeping every 10minutes makes it much easier and start searching with iron = on modus. Good luck!




@ mikipn
I wanna tell you something concerning ground balancing and large coils:

The Jeohunter like alot P.I. mds with large coil has to handle a huge "resistive power":

The coils field is like a vertically spreaded balloon. A small one has to handle around a quarter of a cubik-meter (coin 20cm, large object 50cm) but an almost 50cm coil that can reach up to 6-8m of distance interacts with several cubic-meters.

If you're lucky the ground consists of dry lose earth and the magnetic field goes through like nothing. Or not strong mineralic rocks. But if it starts with water, mineralic salts, low magnetic or metallic stones or even electromagnetic pollution from artificial radio waves it will start to reduce the depth of detection. Powerful detectors have to handle more than 10times of ground resistance not to forget the field of electromagnetical interference that lies beyond the detected object!

Thats why alot P.I. detectors need to reduce their sensitivity otherwise they would detect every single and larger different mineralized stone under ground.

Jeohunter is not a toy but a very powerful tool if you're tough and clever enough to handle it the right way! And if you wanna scan huge areas for finding the real big stuff!


@ RMILLER66

Thank you for your interrest!

Where did you read 80 feet? With the 1m coil you may get 35 feet if there's a long time rusted tank below good ground.

The below values are for the medium coil and as you can see there is a 5x5cm object described at almost 2feet. If the ground is heavily mineralised and if the search coil is 10cm above the surface this can be reduced for 30-50%.
In air tests show that you even can detect a 5mm coin at 6inch (15cm) but @ 100% and directly below the middle of the coil.
So you can calculate how deep you may find rings or medium sized coins.

The Jeohunter is for bigger and deep stuff but compared to other deep searchers it also can find coins. But you have to search more carefully for those. Otherwise you may buy the Minelab GPX 5000 - http://www.youtube.com/watch?v=ckPKAyX6c10 - it is concipated for micro goldnuggets upwards to coins - depending the coil you're using.

It's perfect that you are a bodybuilder because having strong muscles makes it pretty easy searching with the medium sized coil especially on a wider radius (like I do) but there does not exist any detector that can find single coins at 6 feet.

Check the list - those are in air tests I fully can confirm at around 90% sensitivity. If an object is buried for a longer time it can create a larger field (through ionic interaction with wet soil etc.) so you can get up to 20% more depth. But this only works if the ground doesn't weaken the penetration power of the coils radiation! Otherwise you may get the same depth like in air or less.

But: I don't know every secret about the Jeohunters search antenna and if they write that under special conditions it is able to detect 3-4 times of the given depths it may really possible! Haven't tested it yet and perhaps it's complicated rebuilding such test-conditions.

The medium antenna finds a 35x50cm alu-case in air at exactly 200cm (over 6 feet) where there is written below a much larger 60x60cm object at 190cm! So you really can rely on those values and if they tell the search antenna will find under special condition 3-4times of that depth why it should be not true? But if I have the time I will ask the Marko Group what special conditions those are and if it's possible to test or proof it.



btw. - it is wrong if some guys tell you that compared to P.I. VLF systems can't penetrate highly mineralized ground. Those use the same kind of waves and if they have the same lenght and "voltage" they will go exactly to the same depth - just only that P.I. works with a different recognition (feedback, echo system) which is not always better - often it can lead to completly false electronical signals, as example if the very short pulses gets somehow distorted, reflected the wrong way or gets timing problems. In earlier times those pulses were good for saving power and because of the flyback (high voltage) timing but with todays high energy lithium-ion cells its possible creating much more stable VLF or induction balance systems. And the Jeohunter is very stable if handled the right way. Even if the batterie is almost empty it still works as good as stable a high sensitivty.

btw. often beaches are full of junk so a smaller coil is much better. And if you wanna go for rings and coins better save some money and get a good coin detector with simple metal-IDing.

And about the Nokta Golden King:
It's not a bad machine! If you need gas-sensor, GPS, high grafics, digital camera on board, memory and stuff like this pay 1.500-2.500 bucks additional and get one, but the big advantage of Makro Group was (who split up from Nokta) - they tried to keep it realistic, at a reasonable price and with very good - some say better! - quality. There is a huge load of experience since 25 years in those machines! In Turkey they digged out some of the oldest cities in the world and they really know what counts. If you're just looking for coins at the beach the Jeohunter is too big - btw. I've written that already somewhere in this thread - but if you wanna find deep treasures - especially if you're searching with the 1m coil - it's a fantastic detector with a huge detection range and for "highspeed searching" of large areas - like beaches, too...

Hi Funfinder,

There's a guy now in Brazil who became dealer for Makro. He stocks Jeohunters.
My team and I will soon head to a location that has magnetite in all terrain.
The target is already identified by the FG90 and there are some tunnels bellow the ground. We are planning to take the Jeohunter for a drive in order to see if the target is buried or actually hidden in one of the tunnels.

Do you think the Jeohunter will have trouble in a high magnetic terrain/environment to display data for tunnels/air cavities ?

Thanks in advance.

[RMILLER66]

jeohunter use on the beach

Thanks for the information.

I must have been referring to the OKM line when I mentioned 80 feet?

It sounds like minelab 4500/5000 might be my best bet for the beach even though their coils aren't water proof.

I plan to do some deep treasure hunting but unless I find a cave or void I'm only looking at something that penatrates upwards of 6-7 feet deep.

Deep treasure is a great fantasy but lets get real when it comes to bury something deep.

There's a practical limit to burying an object. Physics and soil dynamics play a huge part in burying an object. As an example, the walls of a trench will, not might, fall in when you get to 6 and a half feet. This is precisely the reason why graves are dug to 6 feet and not 7 feet. Without reinforcement, even wells collapse at that depth. To bury an object at 10 feet, you need to dig a circular hole that is nearly 20 feet in width. Have you any idea how much earth is contained in a cone 10 feet deep and 20 feet wide? Probably not.

You also have to keep in mind that most things of value were dug in a hurry...after a train robbery etc.
Digging 1-2 feet to throw in a strong box and cover it up and drag a dead tree or tumbleweeds over it took time.
A 6 foot hole big enough to bury " anything " would have taken hours,especially with the tools of the day.Not to mention a posse on your @&%*
Even if something was carefully buried with no time restraints,that person might need to someday dig it up in a hurry so again I think most buried " anything " is less than 6 feet deep,more likely 2-4 feet tops.

If the Jeohunter can go 40 feet and I'm focusing on 6 feet or less it might just be a machine I would buy.

I'll just have to wait for a google page of reviews before I spend that kind of money on a machine.
At least with minelab you can google any of their stuff a month after it's on the market and find pages of customer reviews and I can't say that about Jeo products.
All I seem to find is a bunch of sites selling or posting their ad on how great the product is and that their world renowned but,NO reviews that say the product does what it advertses to do?

For me only time will tell.

Thanks again for your input.I hope that it turns out to be a great product and if it does,I'll buy it.

first day

Hi all,

Today I drove 400 km to get my jeohunter, and already tested it.

I searched 2 places today and my ground balance ranged from -110 to -160.

I have the medium coil.

I already learned groundbalancing, which is actually fairly easy to do, nice and user friendly interface.

Now I am trying to understand how rest of the device works.

First Example: I found my first target . The jeohunter said gold after i scanned it (3d scan)
When I did the depth scan I gave in the distances of the signal, which was 30*20 cm.
After I scanned depth, the result was suddenly "METAL".

1.Did the jeohunter made calculations based on the size I gave in, in combination with the measurements Mineral, Frequency, Electrical, Magnetic, Mixture and Carbon effect ?

2. About those effects, do all detectors measure those and what does jeohunter do to perform the material determination? If someone have this information that would be greatly appreciated. It will make me decide whenever its really worth to dig.

3. Is the size of the signal (always) the same as the size of the object?

4. What kind of determination does the Jeohunter have: I saw 3 today: gold, iron and metal. Are there other?

2nd example: in my backyard i dug up a lid of a can (size in diameter about 7 cm), depth 25 cm. The detector was groundbalanced -161 and it kept saying gold, even after i gave in signal dimensions. Sensitivity was at 80%. I tried to change groundbalance and did the tests again in steps from -200 -100 0 +100 +200. Jeohunter kept saying gold. What did I do wrong? Or is the value of can lids so close to gold the jeohunter can't separate it?
Funfinder, I saw a post of you where you say you can play with the groundbalance to especially find gold or silver, does it actually work (my kind of soil is almost non-mineralized so i can give it a try)

A hint, If you're getting crazy on cavity signals, look for molehills. I have been groundbalancing for 20 mins before I saw them

greetz,
bunne

[Bunne]

Another thing i found out: the slower scanning over the object gives you a bigger image and thus more details in 3d.

[Funfinder]

@ Hung,

Great you can get now the Jeohunter in Brazil, too.
Well - I have no experience with magnetite-ground - you may test it directly there.
If the shielding isn't too strong it should penetrate the ground. Try with ground balance zero because magnetite could have same value like iron. I wish you much success and tell us about it.


@ RMILLER66

You can watch the Jeohunter videoclips (the links are somewhere in this thread) and there are also exists other reviews in other forums - some links to those you also can find her.

The Jeohunter finds small and deep stuff too that's why its universal.

btw. not everything you can find was intentionally buried by someone. Sometimes huge masses of ground changed their formerly location. Building streets or houses, highwater, moving sand or through waves etc. Not to forget secret chambers or tunnels and sunken into mud or rivers stuff. And depending on the beach stuff also can "sink" into the dry sand - pretty deep.


@ Bunne

Congratulations to your new Jeohunter and I wish you much luck and success!
Your questions etc:

> I searched 2 places today and my ground balance ranged from -110 to -160.

Better first try with ground balance zero to plus 50.


> 1.Did the jeohunter made calculations based on the size I gave in, in combination with the measurements Mineral, Frequency, Electrical, Magnetic, Mixture and Carbon effect ?

The size you gave in has nothing to do with the internal calculations. But the size, alloy, location and shape of the buried items matters that's why some object show up as gold, like round cannonballs too. In air the gold detection may be 100% correct but this can change with different alloys and under ground conditions.


> 2. About those effects, do all detectors measure those and what does jeohunter do to perform the material determination?

It's different. Some P.I.s only can find out the kind of large metal objects and most usual MDs only can detect correctly the metal ID of small objects.


> 3. Is the size of the signal (always) the same as the size of the object?

It depends on sensitivity setting and ground conditions. Usual from 10cm upwards the edges of coil show the vertically border of the metal object or its detection field.


> 4. What kind of determination does the Jeohunter have: I saw 3 today: gold, iron and metal. Are there other?

Gold, iron, steel and different metals:
metal with value 80% most of the time is aluminium or silver.


> 2nd example: (...) Is the value of can lids so close to gold the jeohunter can't separate it?

Indeed - this is often some aluminium alloy covered with the rust of the can that makes it very close to the range of gold detection.


> Funfinder, I saw a post of you where you say you can play with the groundbalance to especially find gold or silver, does it actually work (my kind of soil is almost non-mineralized so i can give it a try)

You can get much more sensitivity for gold or silver if ground balance has plus 50 to plus 150 compared to minus 150. And if your soil is almost not mineralized better search with higher ground balance for higher "valuable metal objects" sensitivity.


> Another thing i found out: the slower scanning over the object gives you a bigger image and thus more details in 3d.

Try using the same scan speed and recognise that 3d image as representation of the detected energy field.


OK, I hope you will have much fun and success with your new Jeohunter. Make some in air experiments so you can learn everything better:
Place detector and coil at some place without metal nearby and try different metal objects how far those get detected. A 35x50cm alu case should get found from 2m distance at 90 or 100% sensitivity and ground balance plus 100. But you also can try what is the smallest thing you can detect - as example some very little coin, nail or button.

And please report it here.


Below you can see 2 small objects I found in the middle of the woods this may with my Jeohunter, ca. 10-15cm below the coil (coil to ground plus ground to object distance)
At 80% sensitivity. Very old button and 200 y.o. muscet ball. This is like finding a needle in a haystack!

[Qiaozhi]

Funfinder, can you supply any links to reviews of the Jeohunter that were not created by resellers? So far I have been unable to find any. Although there were several links to spam attack sites.

[Funfinder]

Hi Qiaozhi,

I found some links. A few also refer to Nokta G.K. because those are almost the same:
Jeohunter is only half to 2/3 of the price, better depth and quality but without
electronical gadgets and detection unit weights less.

Also attached a pic of yesterdays treasure-hunt (dig until 10pm) -
that shows the real distance from Jeohunter medium size coil -
(iron ball 2,5cm @ 15cm & bomb-shard 10cm/4cm @ 40cm)

Thanks for the list.
However, as I said before, there are no independent reviews of the Jeohunter. The links you supplied either connect to youtube videos or forum discussions of Nokta and Golden King. There was one forum that was discussing the Jeohunter, but this was not a review.
It seems that owners of the Jeohunter are either reluctant to share their experiences, or there are very few customers outside of the dealer network.

[Funfinder]

I have no idea why there are so few persons out there describing how the Jeohunter works but now we have at least Bunne and he can tell us what he wants - I don't wanna influence him or tell him he just should say just good things about his new md.

But he should make fair tests and understand the machine pretty good how it works so he can fully give worthful information.

BUT:
If we take the Nokta Golden King as an overpriced Jeohunter with the same abilities there are independent reports or call it field tests:

Look here:
http://www.thunting.com/smf/gpr_othe....120.html;wap2=

There is Ronin who hates the Golden King and there is Hobbyist who defends it and tells his personal experience with this device. And there's also vourvon
who digged deep holes and buried stuff there - his pdf test is in the already above posted zip:
http://www.multiupload.com/CFQY9B1PTZ

Next:
http://www.detektoren.at/eng/gkfunde.html
OK those sell the Nokta but they are trustworthy and the really found that treasure with the golden king that has the same depth and cavity detection like the Jeohunter.
And it was a nice treasure.

If you read here user Minelabdealer he tells the Jeohunter is better than Nokta:
http://metaldetectingforum.com/showthread.php?t=55941

And here the second post from nbkvy2e
http://thunting.com/smf/gpr_other_ge...15.0.html;wap2

"I Have been using Jeohunter for about 6 months and I am satisfied so far with the findings, weight and good ground balance. I have purchased few more machines in December from Turkey and now I am selling them , they are Jeosonars with 3 search heads . I have it listed on ebay .co.uk , search Jeosonar and you will find it . it is the one for 2800 pounds"


Golden King and Jeohunter are exotic and for the most hobby treasure hunters too expensive so they get some of the established brands or for deep seeking some P.I. and those who have one seems to have other interrests than reading forums, writing there and making field tests.

However kellyco sells the Nokta and metaldetector.com the Jeohunter so the big US market can get it and now even Brasil so it will be just a matter of time for hearing more user-reports or seeing clips on youtube. And who really wanna know how good or bad these machines work and if they hit the own taste (this always is a second question...) can go to those shops and test them personally.


Finally the smallest single thing I ever found (it was yesterday) with the Jeohunter:

It seems to be an old lead-button or it was before a very small muscet-ball
Real thin: 1mm at the edges and 4mm at the center -the weight is just 4 grams.
In the middle of the woods at 90% sensitivity and the search was not very slowly.
I guess it was around 5cm (2inches) in the ground.
The detection field was ca. 25cm in diameter.
No P.I. with 1m coil would ever have found this!
