Deepers Detector

[MFC]

Some members of this forun ask for info about Deepers.

Here I post two schematics Deepers 7 and 10, they are not complete yet. I don have the values for Deepers 10 DD but the sch I thing is correct. This is very similar to Deepers 8 AT.

Deepers 7 reversed by me.

All power source of Deepers are the same with a small changes.

if somebody have the values for complette these schematics please post here.

kt315 was going to do a deepers pi project a few years ago it was in his poll, but he never did it.

Hello MFC,

big Thanks

can we made a pcb design together, i would start with sprint layout if somebody is also interested and would help me i think i can do it

I want to know if you want to use this figure to improve the depth or identify iron metal,

depth? 50A through a large coil? yup? look post #80.

China RD people (well mostly reasearch, no development) will never stop..

KT ... Delta Pulse

chinese one got from me gerbers on Delta Pulse in exchange on some micros. i hope whole China are doing DP now LOL!
BTW thats his board, with my remarks. http://www.geotech1.com/forums/album...chmentid=40275

Please forgive my ignorance but why are the electrolytic capacitors marked with Positive to GND?
Is this correct or an error in your labelling?

[Alexismex]

It is not an error because GND is Positive

Deepers 10 FULL.JPG. The LF412 pins at the audio output is error. Pin 5 and 6 reverse

Do not know what the author designed for the purpose of this circuit? Use double d coil to identify iron metal? Then its post-level amplification is correct, is stable, what are the advantages?

Hello again Here is a some correction for two schematics posted by me before.

I will post the hipersensitive search coil 53x25 cm factory details soon. Number of turns, dimensions and exact type of wire.
The frame 1mx1m is made from litz wire type. I dont have numbers of turns in this moment.

The Deepers 8 posted here in the forun is correct, I have been make it and test in ground, very good on a no mineral and low mineralized ground, in red ground is not Good, to many noise even using a DD coil. This PI Met Det is exact Deepers 10 design I think very little difference. The power source for Deep8 is not posted here. I will post soon the Deep 7 factory power source for you and I think is almost Deep8 AT. Same power source Ground(0v) -12v and +6v.

Any doubt or change, mistake etc please email me.
