Jeohunter - Visual Ground Scanner

[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.

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 ,

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!

ZEMĠN AYARI NASIL YAPILIR?
Cihaz açıldıktan sonra direk olarak “ZEMĠN AYARI” modunda açılır. Cihaz kullanılmaya baĢlanmadan sağlıklı sonuçlar alınabilmesi için zemin ayarı yapılmalıdır. Arama esnasında zemin etkisinin değiĢtiği toprak yapılarına gelindiğinde ve tekrar zemin ayarı yapılması gereken durumlarda “ZEMĠN” butonuna basarak zemin moduna geçiniz ve zemin ayarınızı kontrol ederek tekrar zemin ayarı yapınız.Zemin Ayarı AĢamaları
1. Zemin ayarı yapmak için, cihaz “LCD” kısmında açıldıktan sonra otomatik olarak zemin moduna gelinir.
2. Arama baĢlığını yerden 40 cm kadar yukarı kaldırıp “RESET” butonuna basınız.
3. Zemin moduna gelindiği zaman cihaz üzerinde ki zeminin o anki etkisi “Zemin Etki” olarak ekranda görülür. Bu etki zemin ayarı yapıldığında değiĢecektir.
26
4. Zemin Ayarı metal ve boĢluğun olmadığına emin olunan bir noktada yapılmalıdır. ġayet zemin ayarı tutturulamıyorsa, bulunulan yerden yan tarafa kayarak tekrar zemin ayarı yapılmaya çalıĢılır.
5. Operatör cihazın arama baĢlığını “40 cm.” yukarı kaldırır ve reset tuĢuna bastıktan sonra arama baĢlığını toprağa paralel “5-10 cm” yere yaklaĢtırır.
6. Cihaz üzerinde zemin etkisi yoksa Ģekilde gösterilen barda herhangi bir etkileĢim yoktur ve “Zemin Ayarı %100 yapılmıĢtır ibaresi görünür. Bu durumda cihaz arama yapmaya hazır haldedir ve “ONAY” tuĢuna basarak arama moduna geçebilirsiniz.
7. Cihaz üzerinde zemin etkisi varsa, cihazın Ģekilde gösterilen “ZEMĠN AYARI” barlarında bir etki görülür. Bu etkiyi gidermek için “-“ yönde ki etki için “-“ butonuna + yönde ki etki için “+” butonuna basınız. Bu etki kaybolana dek ve “Zemin Ayarı %100 yapılmıĢtır “ ibaresi görülene dek “-“ veya “+” butonlarına basılır.
27
8. “+” veya “-“ tuĢlarına bastıktan sonra arama baĢlığını yerden 40 cm kadar yukarı kaldırın ve “RESET” tuĢuna basıp, tekrar arama baĢlığını yerden 5-10 cm yukarda tutarak zemin etkisini gözleyin, zemin etkisi hala devam ediyorsa “+” veya “-“ tuĢlarına basarak etkiyi gidermeye çalıĢın.
9. Eğer zemin etkisini gideremiyorsak Hassasiyet seviyesi bir kademe düĢürülerek yukarda anlatılan iĢlemler tekrarlanır.
10. Zemin etkisi giderildikten sonra “ONAY” tuĢuna basarak Arama Moduna geçebilirsiniz.

I have a geohunter3D dual system and 3 search coil When I bought a lot of things I found
I love geohunter and I Directly "in the company saw macro Education
Geohunter is a best metal detector. a very good manual ground balance and auto balance.when you detect a metal at the same show's size and depth of metal in the oscilloscope Monitors

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!

ishtar hunter `anladiysam arap olayim birader`... kinda weird English and not understandable at all.. what a magical ground balancing for a VLF metal detector

Yes, I thought that as well.

It sounds like you would have to start detecting early in the day, as it would take until lunchtime before you achieved ground balance.

Hi mkd33
you first setup must can balancing your geohunter if you don't balance you device your detector when search Error occurs and you learn balance is not true.i learn right balance for you ::you power on your detector and so select your language ,your system go to the ground balancing and you must keep your search coil 40cm over ground so detector show the ground number for example 110 so you must press reset button and must down slowly your search coil to The land and you listen your detector sound and see the graphic bar in right side if your detector, sound and graphic show Positive(+ or Like when detect metal) you must keep search coil over 40 cm ground and press + button so again slowly your search coil to The land and listen detector sound if When search coil keep over3cm over ground and you don't listen any sound + or- your device is balancing ------if you keep search coil over40cm ground and you press reset button so you down slowly your search coil to The land and listen Negative (_ or like when detect void) appears you must keep search coil over40cm ground and press _ button so again slowly your search coil to The3cm land and listen detector sound if No sound is heard your detector balancing you must Should it do so When you are close to the ground does not have any effect + or -

Are you sure?

I have built a TwinLoop design from ETI, which has overlapping coils, but they are round.....not nulled.

I know that some PI machines use two coils, but of the ones I have seen, nulling was never a thought, it was just to allow earlier sampling of the received signal.

For the Twinloop I built, it allowed the detector to ignore radio programs and other transmitted electrical noises that some PIs pick up.

Not that I am a PI expert, far from it.......

Perhaps someone else could jump in with some technical thoughts in this area....I am always prepared to be wrong when a full and proper expalantion is available....

I never mentioned "nulling", but simply stated that a DD coil can be used on a PI. This is nothing new.

However, nulling the coils will prevent the pre-amp from being in saturation for the same length of time as a mono, and allows the RX coil to have a greater number of turns, thus increasing sensitivity.

Andy, if you have made TWIN LOOP project, experiment this:

http://www.geotech1.com/forums/showthread.php?t=13622&highlight=sharky

The loop configuration of Crone's is not the best design. Note that for pinpointing they use different coil arrangement. An induction balanced oOo or DOD loop configuration can outperform all other coils when you serch for small targets. Large deep buried targets need large coils, but Sharky achieved enogh depth with normal coil diameters.
