Great work
What's the maximum depth for metal
Can I know how deep the metal is
How I can see cave by software
Thank you
So it is very hard to talk about "depths". Depths will depend on magnetic features of buried object and also on several other factors like soil type and content.
There is no exact method to calculate depths according to signal from these sensor. However there are some empiric methods of approximation.
But that's the topic for books. You'll have to search and read some books about that.
Same applies to your last question; the type of magnetic "anomaly" and how to distinguish among different types. The books are carrying the answers.
I can write here numerous examples about some achieved results with such magnetometer. But it would be pointless. Because each example is a story on it's own.
Some of the results are modest. Some of the results are unbelievable. I bet none of the readers will truly accept some results as true.
For example, 17.3 meters in water on this:

Seems you don't understand my words at all.
Nor you put even a smallest effort to understand.
You'll find your answers in books.

But if you have good will and interest; very soon i will offer SMD kits by affordable prices.
Will be available over ebay soon. I will post the news when it happens.
In meantime you can do lot other similar things on this subject.
You can use John Becker's approach, instead Microchip PIC; you can use simple comparator.
To be able to know when the magnetic changes happen; you have to establish reference.
For example; on single button press to take current value and use it as reference to compare with incoming readings.
Simple voltage comparator will do the job just fine. Before that you'll have to figure out how to convert frequency from sensor to voltage.
Simplest and cheapest would be use of LM331. Look up for datasheet.
Here is the example:
LEDs lit on polarity change, accordingly.
Further you can feed the output to some audio vco.

Sorry don't understand all.
What is "Co będzie zawarte w ZESTAWIE?"
Rest i can translate with online translator.
Ok, kits will be ready soon. (Horrible one month delay from China pcb manufacturer !!!)
I am expecting pcbs in next week.
You can use both type of sensors, any you prefer, you just let me know in advance; so i to set up certain variables in code properly.
