PI Vs VLF Air Tests

Ground that is that minerized when you Ground Bal your just Adjusting for the Signal the Ground is producing.     All that does is change the zero point on the detector.  The detector is unable to define a target if the return signal from the ground is more then the target.

   Your not neutralizing it.  Your not Discriminating it.   Your just adjusting for it.   Works out good if the Ground does not produce the same strength  Signal as the target.

So If the Target produces A VDI Lower or Higher than the Ground then It is picked up by the Detector, ??

	The comparisons are unfair. Both have their advantages and many of us have more than one type of machine. My Minelab, for example, is a work horse and extremely simple. I don't have one of those computerized jobs. I have an El Dorado, Mk III. Works fantastic on the beach and adequately on land. My Tesoro Compadre and Tesoro Tiger Shark are fantastic on dry land and only so-so on salt beaches. In the lakes around here, the Sand Shark can find a tiny chain at 10 inches. That's hard to beat. I have found dozens of those little earring clips in a single day. So small that they slip through the scoop and I have to find them with a strainer. I mean, those clips are so tiny!

Yes, I know what you mean, I was talking to Steve H a few months Back and he told me that my MXT with the 12" concentric coil would have better Depth than my TDI in more normal type Soils, Yet I see people doing live tests with the explorer and the TDI Pro and the TDI is Going Deeper,
It is A Very Confusing topic because I found the deepest Small Item with my Minelab Sovereign GT and The Factory 10"DD @17",

I have come to believe that The Impossible Depths are Reached more By A Fluke of Nature and not because of the Machine,
I have tried to Pin Whites down about their machines and Coils and I asked them if they have been Tweaking their Products and they never said Yes or No, But what they did say was,, There are Always On going refinements going On,,,  I asked them Because My MXT can see my bare Hand and using that 15" concentric it does too and I have tested it and it can see Items smaller than Half A Grain or 0.03 grams, Even the 10"DD can see it So I know they Are Hot Rodding these machines, Because the older models were never this Hot and it can see my Bare hand between 4 to 7 Inches which is just Crazy

	There is an accessory that will find the deepest targets repeatedly. It fits between your headphones. Couple that with experience at interpreting a whisper of a response and you will outperform anyone.

Lol, Yes I agree, I think that maybe less than 5% or Less of people even notice the Third Tone (whisper) as part of their detecting skills, It is one thing that I always practice when I am not detecting in order to recognize those faint signals,, When using that Technique I found it is so important not to have the Threshold up to high To Allow the Item to Break The Threshold Stability, Oh I Love This Hobby everyday Is A Lesson and the learning never ends,

One thing that I have noticed, By using the 3rd Tone system it can Add up to 45% More Depth depending on the Type of Target
