MFD Frequencies?

MFD Question for Tim Williams

Hi Tim,

I started a new thread to ask this question because it may lead to a discussion that is not relevant to the H3Tec testimonial thread where it arose from.

You have established your position that MFD is not the same method as MRI, and does not use magnetic detection methods at all.
While you don't explain how MFD can work or even make a claim that MFD works, you do acknowledge that some people find buried things when they are using MFD signal generators.
My question is about MFD frequencies. I am not opening this thread to argue about whether MFD works or not, only to ask about the frequencies used in MFD methods.

You have stated that MFD methods incorporate a signal generator which uses frequencies found in a table listing the NMR frequencies known to exist in the magnetic field found on the earth.

If we put aside the unknown explanations and arguments of whether it works or not, we have an understandable element in MFD, ....the NMR frequencies.
As you described above, there are NMR frequencies in the audio range for most substances you would want to search for.
We also see people often posting questions of what frequencies to use.

It seems strange to me that anyone would ask.
These frequencies are published in many reference databases.
The only variation of any big importance would be the local earth magnetic field and temperature.
The average local magnetic fields of most locations on earth are published in databases, and the temperature can be found with a thermometer.
(I suppose you would be interested in the ground temperature at the depth you want to hunt for a treasure).
If you wanted an exact correction for the earth's magnetic field, then you could take a portable magnetometer to your treasure hunting site and measure it.
With this information, you could know with good precision what the NMR frequency is for any element.

Yet we see people keep posting requests for information of what frequency to use.
This seems silly, because the NMR frequency is not the same in one location as it is in another, simply because the magnetic field strength and the temperature are not the same.
They would obviously find a more precise NMR frequency by looking at the NMR tables and applying the correction factor for local temperature and field strength:

g = hv/BH

Secondly, we know the earth's magnetic field and temperature are constantly changing enough as time passes to make a substantial change in the frequency.
This is another reason why it would be appropriate to periodically check the temperature and magnetic field strength to adjust for the changed NMR frequency.
And even after we arrive at the calculated frequency, there will be minor adjustments to be made to correct for chemical impurities at the sample which will change the frequency.

So according to the same scientists who publish NMR data, we see the exact NMR frequency will be different when we change the magnetic field strength, the temperature, or the chemical invironment of the sampled element. This means the NMR frequency will be different when any of the following variables change:

1. temperature of the ground where the sample is located
2. chemistry of the ground where the sample is located, and impurities in the sample
3. time of day as the magnetic field and temperature changes
4. magnetic field changed from geographic location where the sample is being measured
5. materials in the ground or near the sample that concentrate magnetic field such as black sand, iron objects, magnetic rocks, etc.

The biggest variable is the geographical location, which can cause the frequency to become double or reduce to half because of the magnetic field strength can vary from double to half.
And the other variables seem to be constantly changing to such a degree I would want to check my calibration every 15 minutes or so to be reasonably close to the actual NMR frequency of an element.
I can envision carrying a portable magnetometer and a probe-style thermometer I could poke into the ground.
But I would see no usefulness to ask people in other locations what is the frequency.
This is because other locations seem very irrelevant to the NMR frequencies where I am located, considering I am at a different place and time.

So there is my question:
Why do people use standard fixed frequencies for MFD methods when we know the NMR frequencies are not standard fixed frequencies for the earth field in different locations and different times?
Why wouldn't a person adjust his frequency to the actual NMR frequency that is found at the time and place where he is located?

I also have a second question:
Why would anyone want to use a harmonic of a frequency when the fundamental NMR frequency resonates stronger?
