This is a commercial project.

Is this an open-source project?
There's a thread here on this forum, but there's only 3 posts on the subject ->

I cannot remember exactly, but I don't think the numbers were very far away from the suggested values.
Anyway, the detector definitely using conductivity discrimination, and not phase, so it's bound to be unreliable.

Yours post #1167 "The ABC values are: A=175, B=493 and C=582." For me those are very far away from: A=300,B=700,C=800. If You want to know how dicrimination works just look at this patent: https://www.google.com/patents/US5506506 You will also find out what those A,B,C numbers are and how they influence to this unit.

For sure it`s not VLF, but show me any PI DIY wchich can do better.. You have mentioned earlier that Your`s "debug numers" where far away from suggested A,B,C soe as Ivconic suggested make proper coil or change cable/357 to get better results.

In tests I did myself, it does [sort of] work in an air test, but it's very unreliable and inconsistent with distance from the coil.

Try burying all your objects in various types of ground and retest and report back with the results.

Who ever the seller is will only sell to a very limited number of countries so its useless

A programmed CPU is being sold without limitation-50 euro

Hello guys
Can anyone give us the complete components list and the pcb to print and the hex code so we can make this project please

Any version of hex of FPI,.not very stable on ground.

3.20 is a non counting version?
