Hello, this is my first post.
I have been reading several of the projects and I am confident that I am at the right place.
Firstly, I know nothing about electronics. I have "bright ideas", but no idea how to implement them. Well here goes.....
All of the pinpoint metal detectors on the market are tuned to a broad range of frequencies.
The higher the frequencies, the more sensitive they are.
I own an Falcon MD20 detector probe. It operates at the 300 kHz range, which covers ALL metals. (Which does discriminate iron). The best and most sensitive detector for finding small gold is the Fisher Gold Bug 2, and it operates at the 71kHz.
So.... Is it possible to take an old coin detector that operates at 6 kHz, and somehow increase the operating frequency to the 71 kHz level? There are other differences, mainly that the coin detector is analog, where the Gold Bug is digital.
Idea #2... how to take a pinpointer and change the frequency. Or how to build a detector that operates at that range and add a ferrite rod with 3 coil wraps.
With all you super smart people I am hoping y'all can help me design and build this.
I look forward to the discussion.
Kerry
