Bill, this is what is inside your water well sounding device. Just a speaker.
And the acoustic waveform it sends looks like this.
Along with the waveform I created last week and launched with a much larger speaker.
So, my method is identical to the well sounder, just much stronger impulse. Now I gotta go monitor the output of their mic amp and see what that looks like.
