Getting a Diagnosis with BioElectrical Devices

I know of, but fairly new to the Rife and zapper world. I have a small "terminator"-like Croft zapper and had a Z4eX zapper. Don't know where it is.

I'm interested in learning more. I have an engineering and nutrition background and I am dealing with a distended/bloated belly, and trying to help my dad. I've seen Rife software, and apps, and other devices.

Is there a way to do scan or diagnose?
Where is a good place to start, either with software, or hardware? Tweet
