While browsing through an old "EPE Magazine" from July/August 2004, I discovered the following article:building a PIC magnetometer by John Becker I had all the components except the fluxgate sensor FGM-3, as a friend had given me a live stream probe from OKM, I said to myself that I had the answer to my question, but when I opened the probe, I discovered something else than the fluxgate sensor, here's the picture of the sensor of the OKM probe, in their doc, they talk about "EMSR SCMI-15-D", does anyone have any data on this system so that I can adapt it to Becker's magnetometer? Thank you

From the looks from your photo and what I can gather from OKM on that number is that is a board from their 3D ground scanner. So my answer would be most likely be NO.
The smart-ass answer would be " You wold have to go back to the future and get a fluxgatev capacitor". Cheesy

A bad day at gold prospecting or metal detecting is better than a good day at work.

a true poet, dear friend, I already knew that this module was not a fluxgate whose pic is attached, I wanted rather to know if someone would support my doubts, namely, I think that the small black component at the edge of the PCB was rather a classic hall effect sensor like a proximity sensor because in the test, this OKM probe did not go deeper than 50 centimeters maximum.
i'm waiting
thank you

The second photo you sent is definitely  a fluxgate sensor. If there are any numbers on the other sensor, I would be glad to research it.

Fatquarters.com used to sell fluxgate mag kits. I built two of them and they worked GREAT! It would pick up my barbeque grill from 30 feet away.
