Steven Gibbs knew back in the 90s that radio shack would go bankrupt and he was right on the money. I predicted this event in 2005 on Paranormalis, but debunkers made fun of me. Well, here we are. Good old radio shack is but a fading memory. People wonder about how such a company can survive.
Maybe, this does not seem important to you. Still, it was radio shack parts that were use in every HDR and this created a problem for us. Where would inventor Steven Gibbs find a new source. Tragically, a lot of old school companies were gone. However, the internet was our savior. Oh yes, Steven Gibbs uses Digikey now. That said, the parts are similar, but not the same. Expect to detect a slight difference in harmonic resonance.
HDR is 80s tech and it did not grow. Frankly, the unit was first built in 1985 and it is an upgrade of the old sonic resonator built in 1981 which is in turn an upgrade of the sonic x. That one was built in the 70's by another man. Bruce Perrault was his name.
