    Turning a pinpointer into a PI - Possible
    by brinbrin
    Hello.

    I've been given this Chinese junk (brand is SHRXY). By sheer curiosity, the previous owner had opened the coil casing. Still working, it can detect a quarter at about an inch.
    I just want to know if any one here has ever tried to make a coil for such a cheap machine. Would...

    SBG- slow motion metal detector
    by scs-bg
    Slow motion discriminator.
    Many have noticed that when a detector is very fast, the depth is reduced. The detector works restlessly and perceives interference. A good solution is a detector that works with slow signal tracking. In this option, there is almost no loss of depth. But then the discrimination

    Hi everyone, I've built many metal detectors but haven't been satisfied with any of them. I've tried digital and analog, all kinds. I'm looking for a stable and truly useful device. I'm waiting for your suggestions. Which device should I build?

    Designing a highly sensitive digital PI detector
    by Nogtail
    Hi! I’m very new to this whole metal detector thing. My experience with metal detectors begins and ends with a toy that came with a magazine I got when I was about ten. From memory, it could barely detect a car from about an inch away.

    I have an application that may benefit from a metal...

    I'm looking for a schematic for building a data logger or any information regarding a data logger that can be integrated via the headphone jack of the Gold Mask Pro 7. I would be grateful for any help, thank you.
