Omega Ground Balance

[all iron]

My Omega Ground Balances at 62 approx here in Terre Haute dirt.

But when i took it to Michigan along the sandy shore it balanced out at 54 approx.

If i took it to a salt water beach, what would it balance out at?

So.... with that being said, What is the difference between the 3 soil conditions?

Does the number directly reflect the amount of minerals in the ground / for example, the lower the number the higher the mineral content?

Is it that simple?

Don't know if this will help,, this is from a F-75 manual...May be the numbers will carry over to the Omega....

The two-digit G.B. Setting number displayed on the LCD indicates the type of ground

mineralization.

Some typical ground mineralization types are:

0 to 10 Wet salt and alkali

5 to 25 Metallic iron. Very few soils in this range. You are probably over metal.

26 to 39 Very few soils in this range -- occasionally some saltwater beaches

40 to 75 Red, yellow, and brown iron-bearing clay minerals

75 to 95 Magnetite and other black iron minerals

Thanks- this is useful and interesting information.

Thanks also!
I sure would appreciate Dave Johnson explaining ground balance for the Omega and what the different numerical values ( when proper balanced ) at different locations throughout the country.

What does this tell us about the soil?

Here is a quote from NASA Tom regarding numerical values in regards to ground balance:

"The Grnd Bal numbers are only an indication of the TYPE of dirt.....................and has nearly NOTHING to do with the VOLUME of mineralization. This is also to say; you may have someone with a Grnd Bal of... say '43' in Illinois. And another person with the EXACT same Grnd Bal number of '43'.....but he is located in N. Georgia. The guy in Georgia can properly ID a penny to a depth of 1". The guy in Illinois can properly ID a penny to 8". They both have the same TYPE of mineralization...............but the guy in Georgia has a much higher VOLUME of mineralization; posing the greatest handicap.
Same thing can happen with two different people.........in two different States.......and both of them having a Grnd Bal of... say '93'. The numeric Grnd Bal ID is not nearly as important....as the VOLUME of mineralization. A better indice would be the Fe3O4 bargraph (magnetite)."

Hope it helps you understand better the ground balance/Fe3O4 readouts.

Many places will have a different range of Ground Phase Read-Out. It is a good general idea reference to how bad the ground mineralization is, but it's only a PART of the information you need. Fortunately, the T2, Omega, Gamma and G2 also provide us with a Fe3O4 reading that helps enlighten us with the amount of ferrous iron mineralization that is also present. The greater the intensity of the ferrous content, the more "mineralized" the ground really is.

Most of the sites I have to hunt around here (NW Oregon) this past several months provide a Ground Balance Phase reading from as low as 76 to somewhere in the mid-to-upper 80's. Generally, we can guess that a higher-range GB read-out is likely to suggest a higher level of iron mineral intensity, and often it does. The sites I am referring to here provide no less than 3 bars of Fe3O4 read-out, and generally much higher. Nasty bad ground.

If i took it to a salt water beach, what would it balance out at?

That will vary depending upon how wet or dry the beach is, the amount of low-conductive salt present, and that combined with the degree eof mineralization of the beach sand w/o the wet salts factored in.

So.... with that being said, What is the difference between the 3 soil conditions?

The difference is that some might be more mineralized than another, some might have more ferrous mineral component, and some, if wet, will have the low-conductive wet-salt properties to deal with.

Does the number directly reflect the amount of minerals in the ground / for example, the lower the number the higher the mineral content?

Usually, not always but usually, the higher-the-number the more negative iron mineralization there will be

Is it that simple?

It can be simple, but the best thing to do is simply adjust the GB for the site you're hunting, AND, once you find some clean ground to bob the coil to get a good Ground Grab balance, bob it a few more times and look only at the Fe3O4 reading. That will be an important indicator of how bad your ground is at that site.

Thank you !! that's exactly what i was looking for
