Anti static guns

Ebuzz, I've never used a grounded brush. My Zerostat works fine so I've had no occasion.

With a name like yours, I'd assume you'd be the expert! <:^-)

I just replaced my old red Zerostat because it no longer seemed to function properly. I now have a new blue Zerostat which works great. The first thing I noticed is that the new one emits a slight buzzy or grainy sound as the trigger is pulled and released which my old one did when it was new but no longer did when I replaced it.

I also try pulling the trigger with the end about 1/4" away from my cast iron radiators while in the dark. I see what looks like a tiny lightning bolt between the end of the gun and the metal radiator.

I still have the small black cap that goes on the end of the red original Zerostat that shows sparks when properly activated. Peterayer is on to something. Find a way to see if it sparks. Engineers?

@ Dougdeacon: that is a good one, I hadn't thought of that with my name. But to all: any thoughts on the unit in the original post? Do you think it would work?

I've had my Zerostat since maybe 1985. Still works great. I have the black cap which verifies function but if you've lost it just put your finger on the needle as your pulling and releasing slowly. You'll know if it works!
