Hello, dear friends and teachers.

Please introduce me a good pulse metal detector in terms of range and stability so that I can build it.
Thank you in advance dear friends.

You need to define more closely what you are interested in, what kind of PI detector?
Ones with small coils and that they are sensitive to small targets like a coin.
Or are you interested in "deep" ones with large coils and good ranges for large objects?
You cannot cover all conditions and requirements with one and the same PI detector.
If you want a PI detector with a small coil, say up to 30cm in diameter, to be sensitive
to coins and smaller targets; Barracuda and Surfmaster PI are the most popular in self-build.
If you want a deep PI detector for large targets at greater depths, with larger coils;
Delta Pulse, Sniffer XR (DBP2010) and several others are good choices.
If you want to try the "digital" version of the PI detector, which can be set to work with both small and large coils,
which decently covers most requirements; FelezJoo is a hit!
But it should be noted that the successful production of this detector is conditioned by a very careful selection of
some components as well as the proper making of coils. Many have tried with different results.
And of course you have several solid projects available in the ITMD 1,2 and 3 books.
Carl (owner of this forum) and George-Qiaozhi (the authors) are the people you should contact for any further info.
I certainly failed to mention a few other noteworthy PI projects.
Over the years, a lot has happened on the forum and there are many interesting projects.

Hi dear friend.

I mean a single coil pi metal detector that can penetrate the soil at least for a 40 or 50 cm object with a 50 cm coil at a depth of 3 meters and have good stability.
Analog and digital do not matter.
At the same time, it has a particle removal system.
I made felzjoo, but it is very sensitive to particles and is constantly out of balance.
I want something much stronger.
Thank you for your reply

That is high demand.
I don't know such detector.

Hello dear professor.

Please, is it possible to introduce a good circuit that you are considering that has good depth and stability.
Thank you for your reply
