Hi, I don't know much about the zapper since I'm just trying to learn myself but since I noticed no one had answered your post I decided to give it a shot. I had seen some Hulda Clark videos at YouTube so I did a search and a lot of stuff came up, several with demonstrations on how to use different zappers, here's the second one I tried (the first had a lady who talked waaaay too much before getting down to it...): www.youtube.com/watch You will notice on that page that there are other choices on the subject so if this one doesn't do it for you try a different video, there's TONS of info at that site.
