Thankyou very much indeed for all of your help. I think I'll buy the Terminator 2 to get me started on something, but I will continue to research this more as I am a true novice. I am in touch with a lady who is an expert (well, you know what I mean :)) on Hulda Clark e and she swears by Hulda's A5. I haven't yet asked her what her thoughts are on the Terminator but I will.
I like to have as much info as I can before I make decisions, but I need to get started and think I'll start with the Terminator. Because I don't know much, (anything in fact) about zappers, I don't know if it's a good thing or a bad thing that the Terminator is a modified version of Hulda's zapper and isn't the frequency different also? Please forgive my ignorance, but I want to learn, but I thought that everything has it's own frequency and as the zapper is supposed to kill parasites, wouldn't changing the frequency change it's ability to kill the parasites?
