Looking for open-source deep PI metal detector schematic

[Carl-NC]

No, and to get more depth requires (literally) an exponential increase in power. You will need a car battery and a 50-amp transmit current just to get a modest improvement. It's a limitation in physics.

Here are the internal photos of the DIY machine I just bought from someone. It's a clone of the Chinese 6103 board.

What is the name of the original detector and where can I buy your board? Are they available on Aliexpress?

Hi Algan, this one isn’t available for sale — it’s made by Chinese hobbyists as a DIY project, and there are no schematics for it.
Still, with a 40cm coil, this machine can detect up to 1.5 meters deep, but its stability isn’t great.
It’s a clone of the 6103 circuit board.

Interesting... and what kind of clone detector electronics does the 6103 board use?

I think it's some kind of copy of the Chinese PI200 https://www.youtube.com/watch?v=32aYqs3E538

6103 is the PCB from the company that cloned the golden mask

It seems to me that it's the PI Polones with VCO.

ask the schematic from the chinese. while i sell something i MUST to give

1. schematic
2. with all Test Points
3. BOM file
4. manual How-To-Solder step-by-step
or, do you prefer to buy the cat in bag????

i am Tombstone? why you are sure silent after my coms? you have to get full info from your seller because YOU PAID HIM MONEY.

各位同事，

请接受我的道歉，因为我没有单独回复每个人。
我从中国的DIY供应商那里购买了这个成品探测器单元。
遗憾的是，卖方已打磨并擦掉芯片上的所有标记，并且没有提供任何电路原理图。

我已经上传了设备的内部照片。如果你能帮我分析和解码PCB电路，我将不胜感激。

该机器具有出色的检测性能：
它可以探测到1.5米深的铁铲，
并检测到5到6米处的车辆。
但是，它只响应铁基金属信号。亲爱的同事们，

Hi,

Could you post a photo of the front panel with all the controls? This gives a better indication of what type of detector electronics it might be.

try find up a gold by different way, sell it and buy MINELAB detector.

OP, please don't post photos of my machine on the forum
