?I am very grateful to my PC but davor cannot read zip files I prefer JPG or pdf file once again thank you for your advice and assistance

[Davor]

I can't post a .lay file other than in .zip format. Can you save it and open with 7zip or some other free tool?

Hello Icvonic, I am here new in this forum. How good is the IGSL to detect gold and as compare with TGSL and TGS. The IGSL do the same as the other detectors? but the different of these is, the IGSL is to use easy with the ALL Metall and the Disc funktion in the same time automataly through the different noises for ferron and non ferron?
Have you got exprience with the IGSL, TGSL and TGS at outdoor within finding small thin of gold and nuggets of gold? In generally, wich of the detectors of this forum is the best to find gold? And how to compare IGSL with the Hammerhead in detecting gold in the outdoor experience? I ask here so much of quistions, because I look for an exemplar of a good detector for build. My favorits are IGSL and Hammerhead. Can you help me with the clearing of my quistions to finish my imagins?
I am looking for your answer as soon with my regards

?The detector ISGl musketer working but too noisy just coil the coil berpungsi tx and rx is not berpungsi. Only 2 Potentiometer potentiometer tresold and near the other BC327 potentiometer and its not working what why and what should I check I just got a multimeter and oscilloscope there is no voltage between each pin number IC is good I use the Board petravka

[Davor]

Petravka board is OK. It berpungsi for me very well There is only one mistake on a silkscreen.
I'm afraid I did not understand the rest of your message quite well.
Your Tx must berpungsi first. You need ~16Vpp there (sinusoid from top to bottom). Next you must make sure that your negative voltage converter berpungsi, and you must confirm that there is a voltage of -6V or so. After that you need to check Rx preamplifier, and make sure that your Rx coil is in balance, so that there is less than 200mVpp in front of the switchers... and so on.

Can you make a list of things you already did, and perhaps make a photo so that I know what you are dealing with?

?Davor coil tx can detect iron but poor and rx coil sangat2 does not detect the metal coil but very noisy sound whether the coil should wear protective AL sorry my English translate davor I will try repairing with your help thanks davor for his answer,

[medj]

Problem in the device does not work, why I put all the pieces
Power is available in all the pieces
Please help
Or, if necessary
Re-building of the new circuit
Please advise
Thank you

[Davor]

Guys, please put some photos of your boards. My intuition does not work without any input.

Hello all together, can anybody answer me about my quistions of yesterday to compare the detectors.
I am have good exprience in elektronik but I didn't have any exprience in detectors of mining.
Great thanks

[Davor]

Your question was addressed specifically to ivconic, so the rest of us did not find it appropriate to interfere.
Basically all the detectors are operating in the same constraints, hence their capabilities are mostly the same. Target response vanishes by 6th power law, so doubling the performance is a huge task. Popular builds are TGSL, IDX, and IGSL. IGSL detects both non ferrous and ferrous targets, while for the single tone devices you may add a two tone mod, or a digital VDI meter to extend your scope. But regarding the depth, all of these are limited to ~25cm depth for a decent coin.

Hi davor why am I seeing positive voltage 9volt in the groud at pin 2..!!!!.7808 and please do reverse the negative pole capacitor 1000uf and petravka plus on board

Hello Davor, have very great thanks for your answer. It is exactly about to compare the differents about the detectors and describe the know how in any words.
The many of this forum writers, told so lot storys as able fary tales without know how about the detector technology and without properties.
At last, only for appreciation of my mind to well done. Then I can imagin wich part is my favorit. At now, I think the IGSL and Hammerhead are my favorit.
Can you say to me, wich detector is the best for to detecting little and big gold exemplars?
Wich is your favorite of the detectors with through your exprience about thouse?
bye

1000uF is drawn reverse on Petravka board. I have no idea how you get 9V on pin2, because pin 2 is supposed to be GND. Please put a photo of your board, and be a little patient - I'll be on the road for the next few days.

Can you say to me, wich detector is the best for to detecting little and big gold exemplars?

That would mostly depend upon your terrains and how much mineralisation you have. For normal terrains and no professional aspirations, I'd say Goldbug or Lobo would stand out for gold. There is a Lobo light build on this forum, but it is still in development. Many people prefer PI machines for gold because those are coping with mineralisation somewhat better than VLF, but popular builds are lacking ground balance, so the only arena these are really good is salty beach hunting.
But the truth is that any detector that you are familiar with, with a little TLC, should do fine. All detectors will detect gold, but depth and size may vary.
