Hello Funfinder (and everyone with a Jeohunter ),

I have the Jeohunter 3D Dual System, and I kinda know how to use it, how to make ground balance. But when I search, sometimes I get gold from metals. Is this normal or is there something with my Jeohunter. And have you ever gotten this "problem". Can it be used to find for example 14K gold? And its maybe not the best place to ask you this, but have you ever found gold with it? And can you explain how you make your ground balance, do you need to take the ground balance and divide the ground balance by 2. So if you get 10 ground balance, you need to divide it by 2, so 5, and then press the + or - button depending on what the Jeohunter says. And is it dangerous for the Jeohunter if the search head (coil), if a couple of drops get on the search head (coil), and dust. That's all.

PS. My first discovery was an bullet from 1917, and if someone knows, there is a lion and a capital letter A on the bullet. Does someone know from witch country it is. It is right after the first World War. I found it in Macedonia.

Thanks ,
MKD33.

Hi MKD33!

Ground balancing is absolutly easy:

The goal to achieve is to keep the detector within the quiet range inbetween cavity and metal signalizing. The more sensitivity and/or the higher mineralisation the smaller this quiet range will became.

Adjust the groundbalance with the plus and minus buttons until you get a value where the detector will not give any sound while you lift the coil from 5cm to 40cm above the ground. On strong mineralic soil this may not be possible with very high sensitivity because there is a strong detection interaction between very large coil and mineralic ground. Solution: lower sens. until it works.

As a rule of thumb: The more mineralisation, the more minus ground balance value.
Hot rocks, loam and clay have around minus 80 while black sand has ca. minus 150.
At deep humus soil, quartz and silicion sand or granite or lime the 0 value will work.

With reset button mod you can reduce the coil liftings "quiet zone" from 3cm to 20cm above the ground - this gives more sensitivity.


The gold detection works but you have to consider gold most of the time is alloy, even natural gold-silver alloy called electrum. There is alot other metal stuff in shape and alloy that also fits into the disc- or better notch-range of gold, like alu foil and alloys containing copper. Also large ball shaped steel objects like cannonballs will fall into this category. However the gold detection works, I have tested it with small golden ring and other stuff.

Greets to Macedonia and great findings with your Jeohunter!

[Funfinder]

PI detectors can already work with DD coils. They have the advantage of better pinpointing, but the mono coil tends to have greater depth.

thx for the info. Greater depth for large objects only? Because the sensitivity zone of very large VLF DD coils in the middle also reacts very good on very small objects.

[Funfinder]

bla bla bla.... only words__!!! but real users say vice versa whatever you guyz claim with huge `only word` ads!
there is no video even with these things, i mean to say no real ground video....! only pre-prepared soil and pseudo tests!

Ronin, you're back. What have you done all the time?
I know you don't like the Jeohunter but have you really found a better detector yet?

btw. We (me and ishtar hunter) are real users and our tests are real, too - for shure.
If you don't like the Jeohunter, why don't you get yourself a cheap PI an walk around
with 1m frame? Or what was the detector you said it works much better as Jeohunter?

Hi mikebg
Thank's of you and funfinder for help
ok but the friend don't know my english translate and write turkish for me and i post turkish pdf for his

[Funfinder]

Thank you Funfinder,

Your explanation is very good .

MKD33.

Thanx!

I've written it already here in this thread, but I repeat it as additional info:

That's another valuable tip - IF the ground is not or just very low mineralized:

Under such conditions you can get better sensitivity for gold and especially for
silver if you raise the ground balance from plus 50 'til plus 150.
Make some ground balance in air tests (use different values from minus to plus)
with a large silver coin or very big copper / alu item to see the difference.

The ground balance itself shifts what is recognised as positive (metal) or
negative (mineralic). As example if you set the ground balance to minus 200
even mineralic stones will give the tune of metal and if you set it to plus 200
it should be possible to discriminate rusty nails without iron off because now
they fall into category mineralic. However with the scan button you always
can check what it is.

Lower ground balance (minus) gives more sensitivity to (long time ago buried
rusty) iron while higher ground balance is better to find deep noble metals.

Some may say now: Oh, that's not good, because I'll get bad sensitivity for
silver on very high mineralized ground. Yes, but with other detectors this may
be similar, if they have a very broad range of different ground-balance!
The extremly sensitivity of the Jeohunter is based to find very small changes
in "field-activity" so it detects smallest changes in ground-resistance, too.

But: Gold is not that strong affected at strongly mineralized soil because
it's conductivity is close to iron AND besides:
It is possible to search even at higher ground balance values at heavy ground,
but the quiet zone of the ground balance in this case is not that wide spread
as with correctly ground balance setting. With reset button mod this is no
big problem because you can set the detector quiet within half a second.


Good luck MKD33, just make some tests until you are used to it and:
If you like bury something very deep and post the test results here!

Hi fun finder
dear my friend thank you of your good post and thank's for your post of ground balance
yes your comments is true but please see this post too
Fore ground balance you don't need to learn number for soil it is very easy :when i was in makro company in turkish learn carefully to me .my english language is not good for this i don't write good and sorry but you see.when you are in ground balance mod keep coil above 40cm ground and so press reset button and slowly Lower coil near ground until put on ground or( keep 3cm above ground) and see ground effect my be is negative or positive .if ground effect is negative you must keep coil above 40 cm the ground again and press enough the -(negative) button until when slowly Lower coil near ground or put on ground removed (negative sound and effect) for test a good balance ,you must Move up and down coil and don't listen any sound from detector & for positive effect you must use +button and repeat the steps above if your device Was balancing press ok button and go to detect.
In during the search you can use automatic balance by Pressing the reset button but( you don't press reset button on metal when has discovered your detector )
Important Note:when you keep coil above 40 cm the ground and press reset before resetting you must can keep 100% and see 100% ground balance so pressing reset button if you don't keep 100% This means that ground is mineral or Below coil is a metal and you must change your area for balance .

Mineral ground don't let me to set any number in ground balance but if the effect ground it was positive we can detect Non-ferrous metal carefully such as gold.And can make deep search.

Searching inside a house

Funfinder, first thanks for all your comments. They are most instructive.

I am planning to do some searching in a old house (over 500 years) with walls about 70cm thick. I will be looking for places people may have hidden valuables and also for a possible escape tunnel (rumor has it that the house had an escape tunnel).

Most of the floors are either concreet (not reinforced with rods) or tiles, walls are made from stone not bricks.

What detector would be a good choice ?

Thanks for your opinion.

If anybody else has an opinion, they are welcome.

Hi FoundIt!

Thx you liked the information. For easy understandable visible instructions how to use it here you can see the newest user guide videos in high definition:

Coming back to your question:
70cm thick walls is no problem if there is large metal directly behind - no prob for any good MD. If you wanna find hidden rooms or cellars you need a detector that is sensitive to cavity like the Jeohunter. But also the stones have to be at least a little bit mineralic so you can detect the difference between massive stone ground and not that thick stone regions with air behind.

You will have a problem to detect a hidden room behind a wall if you search this wall from outside and there are no changes behind this wall. In such case you need to make measurements of the room-sizes and search for places where secrets rooms would have enough space to hide.

Find the entrace to the escape tunnel should be very simple because such tunnels have to be connected somewhere at the cellar or first floor and are surrounded by massive rock. I heard a device called Emfad that works with passive longwave-receiver also can discover hidden rooms and a russian GPR called Loza but you will pay alot more for them compared to the Jeohunter.

I wish you good luck, this treasure-hunting project sounds very exciting, so pls tell us more about your progress and success if you like, especially if you really should use the Jeohunter.

JeoHunter 3D - JeoSonnar 3D: difference?

Thanks Funfinder for that response.

Another question: in trying to decide what to buy, I looked at the description of the JeoHunter 3D and the JeoSonnar 3D; I can't see what the difference is between those two.

Can you tell me what the difference is and in my case (walls and floor) is one better than the other?

[Funfinder]

Hi FoundIt!

Where have you checked the describtion? Usually the only difference is the language (Jeosonar is turkish and I guess arabic, too) while Jeohunter is with english menu for the worldwide market.

Besides the new 3D Dual System is inclusive 1m plus small coil while the Jeohunter or Jeosonar 3D standard version is with one coil and costs some less. Same with Jeoscan 2D - comes with standard coil and costs even more less.

However this is good choice from you because Jeohunter or Jeosonar is very reliable.

I saw a treasure hunting report where they used the russian Loza GPR in some old easterngerman (or was it czech?) castle and the display showed something that looked like a hidden cellar. So they drilled a deep hole through very hard rock and there was: Nothing!

btw. the Loza's 2 antenna system and display is nearly the same as this device for 2500 Euro:

http://www.geotech1.com/forums/showp...64&postcount=3

Maybe the pulsediscriminator works better for cavity as the Loza but you need alot expierence to decode the output pictures correct, it can't see buried metal and you need additional computer or laptop stuff. So the Jeohunter is much easier to use and you get a very sensitive and deep metal detector, too. You also can find very precious meteorites that are hardly detectable with any other MDs because you will be able to detect already very fine differences in ground conditions. Good luck and tell us your progress.

Hi ishtar hunter,

thanx for the interresting Jeohunter test you made here:

Hi GURUS,
I am new to MD’ing, and know only a very little about it.
I have gone through all the pages of this thread, and found many promising facts of joehunter. Here Joehunter and Nokta almost cost the same. Nokta has a better look and feel and some extra features compared to joehunter, but I don’t know if it works like joehunter. As I know both the products origin belong to same group which are now separated. Can you throw some light so that I can buy either of the one.
Second question is, What is ground balance, if I don’t know how to ground balance a device is it of no use at all.
Thanks

If you don't know what ground balance means, then I suspect both of the detectors you mentioned will be too complicated for you to use. This year I met someone who had a Nokta, and after one year he was still having to read the manual and watch the DVD to figure out how to use it. I would advise buying a simpler cheaper detector in order to learn the basics and to get used to metal detecting.
