I use an Audio amplifier unit when I do out metal detecting. I will not post my circuit, as it is fantastic when working.
I and another engineer, in the past, worked and discovered how to amplify the audio sound inside of the metal detector circuits. From it, we could hear the targets
better, and we began to dig FAINT SIGNALS, and low and behold, they were the deeper targets and were fantastic targets.......I promised not to disclose our own
circuit design, and I keep my word until I die. When I die, I still kept my word you see. I never break my promises.............But I post Depth Masters first design!
I started out with a very simple Audio Schematic, and played with it myself. I will stick it in here for the people who want to build their own circuits. It is not
copyrighted anymore as they copied what was posted in the past and took what was out in the PUBLIC DOMAIN!!!!!!!!! Not protected anymore you see...
Lowering the part values, permits more voltage current to travel through the circuit. It increases the amplification ability of the circuit. That is called SOUPING
UP the METAL DETECTORS AUDIO TARGETS.........Do I do this? Yes I did it in the past!!!!!!
That is the secret to increasing the amplification ability of any voltage circuits.....More voltage current in the AUDIO section, amplifies the
FAINT TARGETS, and one digs up fainter targets, and finds things others could not hear with their own metal detectors.
Here below, is the FIRST DEPTH MASTER audio amplifier. Take it, play with changing the PARTS, and one will be able to hear fainter signals, and will
be able to find DEEPER TARGETS...........They used to make money selling Audio Amplifiers that plugged into the audio plug of the detectors!!! They
are out of business now, I do not see them selling anymore audio amplifiers... Start with this very simple AUDIO AMPLIFIER that they started with in the past........
