      Esteban,
      If what you are trying to detect is a local anomaly in the electric field ,but this field is variable by nature, why dont you make 2 detectors,use one as a noise cancelling system ,the other for searching ,and both signals mixed so you only detect the real anomaly?

        can someone give me some of the post of Esteban explanding the signal please. I need to read or reread them thanks.
        Carl do you know some of his post on the signal?

          For sure it will keep you occupied for a while....
          BTW, could you share results and pictures of your experiments?
          you were asking all the time for diagrams and info, so you could build all of them, how it went?

            I wish to made it. Much filters, also poor detection... Saw an old circuit in J. Markus book wich can detect masked signals by noise, and this noise can be more in magnitude than useful signal. This uses a square wave 60 V peak to peak as reference.

              Yes I build some of the circuits and all of them from Carls circuits to others DID NOT WORK FOR ME.
              BUT ALL THE METAL DETECTORS ( BFO,IB OR TR,PI )I MADE DID WORK.
              FUNNY THAT SOME PEOPLE CAN MAKE THEM WORK(OR SAY IT WORKS) AND OTHERS CAN'T.

                If noise is random,it should cancel itself.You just need to invert one of the outputs ,if you use the opamp idea just reverse it and mix the output , then with both detectors in parallel you should detect nothing, as long as you separate them or point to 90º should begin to see results

                Many says they dont work, but among them i dont see (m)any that actually built them.
                Actually i am one of the few that did (seriously) , i could find some strange and yet unexplained behaviour. Did you? If i may give you an advice,don´t spend too much time lurking around, or you will have no time left to build and field test them

                  Fred, maybe you're right...

                  Also I know in forum many persons can't replicate with success "normal" MD. This is, some scientific devices as MD based in principles known for all.
                  I will no insist in some things. To make a stable BFO maybe is an "art"...

                    Three guaranteed methods to pick up a gold signal from more than 10 feet every time

                    Here are some tests you can try that are designed to allow you to pick up a gold signal from long range:

                    Test 1:

                    Get a small battery powered radio and a gold coin. Turn on the radio and tune it to a strong station, then bury it along with the coin about 2 inches deep in dry soil. Walk 10 feet away and turn on your LRL. Point it all directions and see if you can find the hidden treasure. If this doesn't work, then turn up the sound on the radio and try again. (This method takes advantage of an audio signal emitted from the location of the buried gold, and radio).

                    Test 2:

                    Get a small battery powered AM radio transmitter and a gold coin. Turn on the transmitter and then bury it along with the coin about 2 inches deep in dry soil. Walk 10 feet away and turn on a portable AM radio that uses a coil antenna, and tune it to the same frequency as the transmitter. Try rotating the radio all directions until you find a null position. Continue moving around and rotating the radio to see if you can find the hidden gold coin and transmitter. If you can't find it, try lengthening the transmitter antenna so it reaches near the surface of the ground. If you can find the hidden gold coin, then you may honestly claim that your AM receiver is a treasure locating device because it produced a treasure. (this method takes advantage of the electromagnetic waves sent out from the location of the buried gold, and radio transmitter).

                    Test 3:

                    Get a quarter-stick of dynamite and a gold coin. Dig a hole 6 inches deep, then drop in the gold coin and stick of dynamite. Fill the hole until only the top of the dynamite showing. Light the fuse and Walk 100 feet away quickly. Soon you will hear an explosion, and you will see things flying through the air. Now go back to the hole where the gold coin was. If you are lucky it will still be there. If not, then we can see that the amount of energy released from this gold signal is very large. The coin has probably shifted its location. If you can't find the gold coin, Don't worry. Your test was still successful. The signal accurately marked the location where the gold coin was at one time. This is all that is required to prove your LRL works! It has never been necessary to actually recover a treasure when proving your LRL located it. (This method takes advantage of an audio and visual signal emitted from the location of the buried gold and 1/4 stick of dynamite).

                      I believe that the portable radio will work better with ferrite !!!!!

                        From what I read here the LRL is not sensing the gold object but the ground surrounding the gold object or maybe an electrical charge or ions around the gold object.
                        So you need to forget about LRLs actually being able to detect gold.
                        You need to find an incredibly old gold object in the ground and make a device that will pick up that halo or whatever else it is called.
                        If a LRL actually picks up the gold itself, then there would be a means to know that it actually works.
                        I hope I haven't misrepresented the usefulness of LRLs.
                        I know, I know, it sounds incredible doesn't?
                        Just have faith that they work, then make one or buy one since you will never know for sure if it really works or not.

                          Hi Geo,
                          Of course an AM radio works better with a ferrite. In fact, most AM radios have a ferrite rod placed inside the coil antenna to improve performance when a small coil is used. However, these radios still use a coil for the antenna as opposed to a whip antenna. And this coil type antenna is responsible for the phenomenal directional LRL abilities of an inexpensive portable radio.

                          Best wishes,
                          J_P.

                              Maybe, is not good idea to use IC for eliminate noises and also great part of the signal generated by the "phenomenom". Do will better reference voltage in opposition to noise? This circuit claims that can be detected useful signal masked by noises, even if noises are superior in magnitude than signal... This uses a 60 V peak to peak square wave as reference. According the text, can be detectable signal in order of milivolts masked by noises... 1964 circuit and maybe forgotten, but don't know if is useful, but is interesting.

                                Esteban,
                                I am not talking about cancelling the noise, but cancelling the signals of 2 identical devices, one with the needed signal the other without.
                                This way you can remove the natural variations of the field you want to explore.
                                Below i call this e-field but you can call it whathever you want :-)
                                Regards,
                                Fred.
