Wow, nice ad there Allen. But I'm there with you about the need for a Clark style zapper. The battery wave works way much better than any frequency based Rife type zapper, Since it would have to cover around 550 or so frequencies, Dr. Clark found.
I have used many type zappers over the last 15 years, and found any of them to be effective enough to do all those things (beat off a stage 3 liver tumor) if you do the herbs in the protocol of Dr.Clark. My current choice is the SCADA RSG-4. It works fine. It has all the electronics and battery in the hand holds. I tend to pull the box kind off on the floor, and it eventually breaks them. :(
Anyway,Dr. Clark's son invented the zapper, and she really learned to use it properly. I'd advise checking her book, Cure for All Diseases' out. (Free download here.) She covers a lot of environmental clean-up, including the highly profitable dental clean-up. I think she was coerced to do so or endure even more harassment/possible jail time (again).
But the cleanup info, while not nearly as horribly necessary (especially the dental one) as who ever actually wrote that part of the book makes it sound, does give good ideas for where and what kind of toxins you should be on the look out for. Like gas fumes or freon out of a leaking fridge.
But I read and did her protocol 15 years ago, and the maintenance ever since (stopped zapping for a few years, doing only the herbs, thinking by now that should suffice, but nope, without zapping the worms just crawl out of the digestive tract where the herbs can no longer kill them and started up the cancer) but haven't done one of the 'necessary' clean-ups and I'm great, health wise.
By my reckoning, if all that 'designed to be overwhelming and make you give up' terrifying clean up crap was so vital, I'd hardly be well yet, eh? So I say find the obvious things like a leaky furnace or car muffler and don't let them terrify you with teir lies.
