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.

Great reference for RIFE devices
Format: Paperback
I've been using RIFE frequency sounds for addressing some problems. Now I got an affordable RIFE device that comes with tons of programmed setting, yet impossible to cover all. I like this books is very well organized and includes lots of good information that will allow me to program my own settings for specific needs. I do recommend it to any person interested in getting these frequencies on paper. Worth the investment.
