Great information!
Format: Paperback
This is a very well designed book with so much information. I wish there was a more detailed index in order to find what you need. In my book, the first index page was missing!

very helpful Rifing book
Format: Paperback
still learning to use this book as it is a wealth of information about Rife frequencies. I have GB4000 and SR4 equipment and this supplements the Universal frequency book that came with them. This book was recommended by folks in the online GB4000 Users group.
