I think you need to be more specific in your search terms.
I normally don't use Google, but tried it for zappers as follows.
Without listing all Hulda Clark, Parazapper, Don Crofts zapper and others.
Give it a try.
I have been using the internet since its beginning so I am highly aware of how to search.
Whoa, did parazapper get up on the wrong side of the bed this morning?
I told you I don't like Google either, and I don't use them for my searches, but the same kind of search efforts I try to do get me all kinds of goofy results.
I was trying to help by suggesting the two key words to get a medical zapper search done and it worked.
This doesn't mean you have to give up your hatred for google.
