Am I correct in surmising that most of us are using the "hold the trigger in then release slowly as you move the gun away from the LP" method? Seems like ghosthouse does. Yesterday, I searched Youtube for videos like the one cited above. There you can find several different would-be gurus touting several different ways to use the Zerostat. I did like the demonstration that a Zerostat treatment can cause a charged up balloon to fall off the surface of an oppositely charged LP. I would accept that demo as "data".
My neighbor up the street owns a system in which he has invested well north of $100,000, maybe north of $150,000. I observed that he haphazardly squeezes his Zerostat rapidly and repeatedly over the LP, without any regard for avoiding the clicking sound and without the "hold down" final step. When I advised him that his technique is not optimal, he gave me a quizzical look and basically showed no interest. This is a guy who uses cable lifters, ICs and PCs that each cost in the 5-figure range, those crazy things that are supposed to change the room air to promote sound propagation, $100 fuses, etc, etc. Each of us is crazy in a different way, which makes this a great hobby.
