As many of us who have great audio detectors like Minelab, if you don't use them regularly like those of us who have snow on the ground half of the year, having to relearn the audio tonal signals we receive in our earphones can take up several sessions each season to become proficient again. It has to do with the ability to learn. Some are better learning through audio response and some are better learning through visual response. You know as an adult, which one of these categories you fit into.
For those of us who learn visually, sounds can literally go in one ear and out the other.
There are devices out there that are used for many purposes to measure sound frequencies which audio detectors put out and can convert the tone to a frequency display. As it seems that different metals put out different tones, with a simple electronic memory device which can be a tone learning device, it would be easy to make a device that could be used as an accessory with a small microphone placed in the earphone to measure the tone frequency and convert that to the most likely corresponding metal on an LCD readout.
Now where can we get one or who can design and build it?
Sorry if this is an old tried and failed idea but just a lightbulb moment.
