Detector #2

[Zocky-Zocky]

Funfinder!
My congratulations on this your detector. I like it. I think we need to work on its further development.
I would like to pray, if not a problem, the following information:
1. Induktivity and resistance of the antenna 15 cm;
2. Cross-section of copper wire in millimeters, from which the antenna is made;
3. Resistance Plate antenna;
4. Dimensions Plate antenna;
5. From what kind of metal is made Plate antenna;
6. Are the values of resistors on your schedule in ohms (ohms) or Kohm, and
7. Have you used an active speaker with its own audio amplifier?
Many thanks you in advance for your response!
Good luck in future investigations of wishe!

Hi Zocky-Zocky!

Thx for your interrest but for now I have no idea how to improve this stuff. The EMFAD detector uses passive long wave receiver that can find EM-field concentration but what we'd need is to get the "reflection field" of metal objects inbetween the underground electrostatic field.

Modern earthquake-warners can detect the current of bedrock if set under friction or pressure like it is used in piezo-lighters but yet I have no idea how to use this for metal detection.

Answers to your questions:

1. don't know but these values are not important in this case
2. 0,25 or 0,30 mm
3. no idea
4. ca. 25x15cm
5. iron tin, but you can use anything
6. if there's written no k the ohm values are below 1000
7. the activ-speaker has an amplification, but not alot

btw. if you're using a larger plate antenna you can get even more sensitivity. Good luck with your experiments!

@all
You may have forgotten my question...
Which detector can find a 3cm diameter coin at 50cm depth?

I guess it really could be the: The Minelab GPX5000!

Maybe after upgrading to The Minelab GPX4500!

Well,in my field test,MINELAB GPX5000 cant go deeper than NEXUS standard SE...
The MINELAB is beter for finding nuggets in mineralized soil.
Maybe your minelab coil is biger than 14" ,to get this deep results.

Good luck with the circuits - with building, testing, analysing and whatever.
And no stupid comments!

Thanks for the design, the one with integrated circuit you set up? Is it the same circuit at the beginning of the post?
Does the box have to be wood or other material? I'll ride because I believe in your technology, hugs

Hi
Thanks for posting schematics.
I don't quite understand how your IC1 LM358 is used ... pin2 (IN-1) and pin6 (IN-2) are not connected to anything??

Thanks again.

The same way that you registered in the LongRangeLocators forum.

Still waiting for an answer.
