It has been 4 years since I posted asking for some help to find an LRL circuit that would fit inside the plastic stud-finder in my photos.
See here: http://www.geotech1.com/forums/showt...light=designer I have received no schematics for circuits to put inside the plastic studfinder. What should I think? Are Geotech experimenters not capable of showing me a simple LRL circuit to fit inside my plastic enclosure that will find millions of dollars worth of treasure?  Best wishes, J_P

Hi iron1944!
A very interesting scheme! Please tell us if you can answer these two questions:  1st - How exactly is called a book in which this scheme was published, author of the book, year and place of publication, and 2nd - Can you put a full page 8 of Electrical parts list. Thank you in advance! Zocky-Zocky

Thank you for your circuit. Now I see a circuit that will fit inside my stud sensor. At least all except the handles and the antenna. If you are looking for an analysis, It seems pretty simple. Since R1 is 1 meg, it is looking at small signals. The electronics are designed to detect slight variations in the resistance seen across the two handles. But at these small signal levels, there may be other electronic events influencing what is sensed. It appears that any sensitive amplifier matched to the handles could work as well, such as the modified zahori amplifiers, or the ivconic ion sensor amp. But this one is configured as an oscillator which varies according to what is seen as a resistance at R1. I am not sure exactly what advantage this has over a simple signal amplifier, but anyone who builds it will probably find out. Looking closer at what the circuit is sensing, it is designed to sense the resistance that is seen through the hands of a person holding the two handles. Electronically, anything placed inside the metal box would not be expected to influence the circuit. I would think that if the antenna picked up a stray charge from the air, it could change the relative charge of the person holding the handles, depending on how well his shoes were insulated from the ground. Maybe this charge from the air could have some influence on the circuit. And if a charge imbalance developed between one hand and another while holding the handles, this could cause the oscillator to vary as well. Also, moisture on the handles and the enclosure could have an influence if it provided a conductive path for current to leak from one handle to the other. My guess is this circuit was originally designed to measure the resistance across a person's hands to show any resistance variations. If this was the original intent of the circuit, it appears to have been modified to add an antenna and a metal box to hold a sample. Does it find treasure? I don't know. I doubt it. But testing it would tell. Best wishes, J_P

For longer range without touching the antenna to the gold, I believe the maximum depth is about 2000 miles with radius of 4000 miles. I believe you will find gold with this device within the 4000 mile radius of any point located less than 2000 miles distance from where you are standing. Point the antenna any direction, then turn the control until it beeps. The beeping will indicate you located gold. Remember, you can also find this same gold detection without using any electronics. Simply point your finger any direction and you will find the same gold within 4000 mile radius from the spot you point to. You may point to any place, up to 2000 miles distance from where you are standing. You should find there is gold within a 4000 mile radius of that point about 99% of the time. Best wishes, J_P

Hi J_P. Before years i constructed two similar devices who had the same operating principle, the measurement of the hands resistance. Results was not good so i believe that this schematic don't work. Regards

According to the diagram in my opinion,
Sending a pulse to generate electricity with a static ne555 mechanical shape. Gold itself does not produce static energy is not suitable for this project I think he kind of circuits we have seen, but they did not know the project, and I see that we have to do research on. m sorry to google translate. thank you

I believe you found this kind of circuit did not work for you. But maybe you did not understand how to use it correctly. I tried to explain the correct way to locate gold with this LRL in my post to mesy64, but maybe I did not explain very clearly. So I try again: I believe this device cannot find any gold unless you touch the antanna onto the gold that you are hunting for. When you touch a piece of gold to the antenna, then you will hear a noise in the speaker to indicate that you located gold. The sound you hear will be the sound of locating the gold you touched to the antenna. I think the gold may make the same sound as when you touch the antenna to a piece of copper or lead to locate copper or lead. I am very certain you will hear the sound of locating when you touch the target metal to the antenna. For long range detection, it does not work the same way. For long range, you cannot pinpoint. You must point the LRL in the direction you want to search, then turn the pot R5 and R14 until you hear the sound. This sound tells you you have located gold in that direction. The gold is located somewhere between where you are standing and 2000 miles distance from you. It may be located above the surface of the ground, or buried up to 2000 miles deep. But it is there for certain, because the LRL made the sound, and the meter moved. Because you cannot pinpoint it any closer than 2000 miles, you must dig many holes until you find it. You may also need to dig off to the sides up to 2000 miles as well because of the poor pinpointing ability. When you finally recover the gold, you can touch it against the antenna to hear the sound and to prove the LRL detected the gold a second time.  Best wishes, J_P

At final you have wrong. If you touch it against you Reset the detector Regards

But in the process of resetting, you should hear the sound change for a short moment. This is the actual sound of detecting the gold piece that you are touching against the antenna. Also remember... you must set the controls to make it sensitive to touching things against the antenna. I have not built this amazing LRL circuit yet because my studfinder shows the same unbelievable performance for finding gold without making any modifications. Think about it... I have 2000 miles range when using the long range mode. Why would I want to make a modification? Now to solve the pinpointing problem...  Best wishes, J_P
