This is the most often used kind of MFD which some people say they have success with: http://www.geotech1.com/cgi-bin/page...mfd1/index.dat
You can find instructions also for making the rods here: http://www.geotech1.com/cgi-bin/page...lrl1/index.dat
This is the same kind that Dell Winders sells as Omnitron, and many others make copies.



When you finish the circuit you can connect the signal out (+) and (-) to the two brass rods that you push into the ground.
Turn R5 to make adjustment of how much voltage you send to the brass rods.
Turn S2 to switch to different frequency.
S1 is to turn off power.


Best wishes,

I know this much about this circuit.
I want to know how to find gold and silver, this circuit helps? What reaction occurs When the probe is connected to the earth?
8038 will produce a sine wave with a frequency 5 kHz and 8.7 kHz.
I believe you instead of the Ic 8038 using a sine wave producing circuit 386, and instead of a transistor amplifier used for current and more
ok?

Hi ma330,
There are many MFD designs which will put out a frequency.
Some designs use a digital oscillator like a 555 or simple digital gates set to produce square waves.
The preferred method is to use a frequency generator IC that can produce a sine wave.
The 8038 is obsolete, and there are several others that replaced it.
You can also make a transistor amplifier that can produce good sine waves or sloppy sine waves depending on how complicated you want to make it.

Most MFD users think that low power is good, and high power will not work very well for locating metal.
But a few say they like more power.
You could use an audio amplifier connected to the output if you want more power.
But you will probably need an amplifier that uses a higher voltage than most audio amplifiers if you want to pass more current through the ground.
Keep in mind most MFD users think high current is not necessary.
They prefer the 5 volt or 9 volt low power designs that pass small current.

The frequency will not be the exact amount you want.
You will need to make adjustments to the capacitor values at C1 and C2 to until you have the exact frequency you want.
If you are using a function generator IC to make the frequency, and you are using polycarbonate film capacitors, then the frequency will be very stable, and will not change much when the temperature changes.

how to find gold and silver, this circuit helps?
What reaction occurs When the probe is connected to the earth?

Here is what the person who posted that circuit says:

How to use the MFD:
At this point you should be ready to try out the MFD. Insert the two probes into the ground about 2-3 feet apart. Using banana wires connect the probes to the MFD transmitter. Turn on the transmitter and grab the L-rods. Walk a circle (about 10-12 feet out) around the probes until the L-rods cross - you have located a potential signal line. Mark this point. Imagine a line connecting the marked spot and the middle of the probe area. Move farther away (say, 30 feet) along this line and, using the L-rods, try to locate the signal line. Continue moving away from the probes as long as you are able to detect the signal line. Make sure you mark all of your signal hits.

MFD Techniques:
At some point as you move farther away from the probes you will cease detecting the signal line. If you detect a signal line out to a certain distance from the probes but the signal seems to stop, then where it stops should be the location of the target. Before you dig, you can verify this by moving the probes 90 degrees around the target point and triangulating. The target will be at the location where the signal lines cross.

MFD Triangulation:
There are two potential pitfalls with MFDs and both are due to the incredible sensitivity. An MFD has the ability to pick up target signals from as much as 10 miles away, though 1-3 miles is more typical. This means that it can take quite some time and effort to trace out the signal line. Once you have the target pinpointed you may have to face another problem: depth. The MFD can detect targets as deep as 100-200 feet, so locating the target is only half the battle. If a metal detector does not verify the existance of a metal target at the identified location then you should bring in excavation equipment. If no obvious target is found when you reach 200 feet, then the target was most likely subatomic gold particles - you cannot see it and most chemical analyses will not detect it either, but the MFD will.

Be certain to read all of his instructions including the end of what he says for using it and making detection.
He says you should be ready to bring tractors and backhoes to dig a big enough hole to find the buried treasure, because you may have a hard time to find it even if you have metal detectors.

Also read what he says at the end of his project for building the rods:
At this point I hope you have built and tested some of the described LRLs.
They are fascinating devices, not in the sense that they can locate remote buried treasure - which they cannot - but in the effect they can have on the psychology of the user.

According to the designer of this circuit, MFD generators cannot locate treasure.
But if you want to believe it can locate treasure, then I am sure you will find people who will tell you what you want to hear.

Excellent j-p
Thank you for your useful information.
I suggest you do the work for voltage output, 5 to 9 volts?A sine wave oscillator and amplifier with low power for the common good?
Using a sine wave oscillator with two outputs and the ground What is it?
I completely did not understand some parts:
How to use the MFD:..............
MFD Techniques: .............
MFD Triangulation:.........................
It is possible for you to show me parts of the graphics?Painting?
The best moment for you

The circuit you see above is already a low power circuit which puts out a sine wave and does not need modifications.
You can adjust the voltage at R5 from zero volts to nearly 18 volts.

J PLAYER, you are so full of BS, you couldn't tell the truth if your life depended on it.

Shame on you for posting false information to unsuspecting viewers. Dell

I'VE SEEN Dell Winders machines and JP is right on the money. Only difference is price and the signal generators which on Dell's machine is a worked over off-the-shelf signal generator that will run off a battery and the JP device that generates the signal with a simple chip. Anyone with 2 brain cells operating can build the JP shown device including the rotator rods for $30 or less. They both do the same thing - NOTHING WORTHWHILE!

I've seen several of Dell's machines, and while they don't have "the same" circuit as the 8038, they definitely have "the same kind" of circuit. So JP is right.

The shame is adding useless electronics to a pair of dowsing rods and passing it off as anything more than... useless.

Yes, this ground conductivity (apparent of ground resistivity) VLF method has some potential. Worth for further research. But not in connection with dowsing rods.

hi to all
What is the best in class amplifier to boost the frequency to penetrate to the ground(for mfd)?
A?B?...?
please answer
TANK YOU

[WM6]

Trick is not in force, but in correct measurement.

You can use one 5-10W audio amplifier chip.

But if you still trying with L-rod combination, you probably need 5-10kV pp to sense something.

CLASS A, Because Class-A Output devices conduct through 360 degrees of input cycle.

The circuit further searches metals
The only problem is, there is no frequency variable capacitors suffering?? Gold and Silver
