Looking for Advice: Best PI PCB for Deep & Stable Detection?

[55323352]

Hello everyone, I'm planning to purchase two models of Pulse Induction (PI) metal detector PCBs. However, I don't have much experience with them.

I'm looking for a PCB that performs well in deep detection and is also very stable. Could you please give me some professional suggestions on which one to choose?

Thank you very much for your help!

Hello,
none of these are deep-search detectors. The Clone-PI is more like a regular Pi detector with a microcontroller. It can't be modified because, to my knowledge, the source code isn't publicly available. However, you can connect a frame coil. I have seen a coil table somewhere for different DIY coil sizes.

GeoMax,
Hello, could you please share a complete set of well-designed DIY materials for a pulse induction metal detector, including the schematic diagram and PCB files?
I plan to build one in China. Most valuable metal targets at a depth of 1 to 2 meters have already been dug up here.
Therefore, I need a pulse metal detector with deeper detection depth and stronger penetration capability.
Thank you very much.

buying at ebay you can not get consultations. ebay messages box does not allow to send files and links. forbidden.
while i did sell there i offered to go in GEOTECH, no another way. a correspondence via my email was of a nature of typical spam messages flow.

Hello,

Unfortunately, I don't have any complete, well-thought-out DIY instructions for deep-seeker PI detectors. I'm only familiar with the posts that have already been published here on Geotech. Perhaps the SuperScan PI detector would be something for you. It's a depth finder using PI technology. You can also find the schematics here on Geotech, but only the schematics. There are no PCBs.

Hello forum,

Besides the ones listed below, which can be found on Geotech or elsewhere, does anyone know of any other available PI depth finder diagrams?

Delta Pulse/Sniffer XR71 (both are about the same design)
Sniffer XR7/DBP2010 (both are about the same design)
SuperScan
Lorenz LP5

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

Why shouldn't pictures of your detector be published here?
The PI-Polones with VCO is nothing special. Everything about it has already been published here. Many have replicated the PI-Polones and are still selling their boards. So it's no secret. There are known variations with VCO, without VCO, or with an additional discrimination board. PI-Polones clones are very popular in the Middle East, North Africa, and some Asian countries. The RAMSTAR 5 from Poland is also a modern PI-Polones clone with depth detection and discrimination circuitry. You can find more about the RAMSTAR 5 on YouTube.

“”YHLThis Chinese friend is really something. Did you apply for a patent? Aren’t you just copying someone else’s idea anyway!

You can see, I changed it more than ten years ago, and I have identified and applied pressure control changes well. The reason for not publishing is a trade secret, and many people in China just want to copy and sell it. +For example, the OP also wants to ask you about the circuit diagram of that machine, and the circuit board information is just done by oneself. Here, they are all requesting without any contribution.

I want to ask you, what you posted is my work, I don't need a patent. Can I tell you not to post? You can post other people's things that I can't control. I'm just persuading you not to post my work.

My Chinese friend, I don't need to plagiarize others, because Polish Pulse was extracted from a Polish website and posted on this forum for modification ten years ago. Look at when I registered as a member. You have to put in effort to reap rewards,

[55323352]

Could you provide any proof that this solution is original to you? This approach has long been mature and popular across various forums and is not your own creation. You appear to have copied it from others. Why do you restrict others from sharing it publicly?

[yhl]

It's not enough to have a good circuit to be useful. You need to understand how to modify it, such as working state, current, voltage, duty cycle, frequency, and delay sampling length. I can redesign other circuit diagrams and understand their working principles. I don't have to plagiarize from others. I understand the working principle and don't need any circuits. I can build a good circuit by using other accessories according to the principle,

I'm sorry you didn't understand what I meant, and I can't restrict you. You can post whatever you want. I don't have a patent, and I didn't expect anyone to post my work. I'm happy and interesting to ask you.
