yes ican project for epe 877

thank you

I think mr Epitopis have a working magnetometer and working dataloger.Buth problem is in recorded data format and represetation this data in some geo software..
Regards too all!

Have this one.. works OK but not very suitable for logging carl's gradiometer.
Thats why i am looking for data Logger for Carls gradiometer
so , if someone can help us !!!!

Magnetometer - Gradiometer

who can help me please here to connect those two pcb ?????
the gradiometer and datalogger
there are some numbers on the box of datalogger and 8 pins on the pcb of gradiometer , which are the correct connections between them?????

Hi friends,

Did I can find or detect gold and treasure under soil
by Epe pic magnetometer ?

Or Epe pic magnetometer only can detect iron
and ferromagnetic metals ?

Thanks...

Hi epitopios,

Thanks...

Thus the best choice to detect gold in 2-3 meter depth under the ground is only PI metal detector ??? yes?
what is your propose...?

Hi zenit52
I am just a radioamateuer and very fresh here in this forum with so many guru in this hobby , i just find out that my gradiometer shows me from a distance of 20 - 30 burried things , then the next step is to find out what is underground , so its up to you what you use next , a good metal detector to find out the ferrows and non-ferrows metals ?
the next move is yours
* next days i will see the bionic machine of a friend

LC oscillator

The inductance changes because the coil is wound on a core with high permability. It`s inductance changes when influenced by ferromagnetic materials. Seems as if the sensor electronics is some kind of square wave LC oscillator.

Hello Olsteffe

Very close !
It seems that the sensor is a Armstrong oscillator ( thanks Ivica !), the coreform inside is a metal strip like vitrovac or metglas. ( both work )
If you look at Yahoo magnetometer group you can find more info !
There is a circuit that works !

Hello Epitopios
Do you have the complete article? I can just find parts of part 1 and 2
