Earth Glows Plasma systems are based on high voltage electrostatic pulses instead of RF carrier waves.
Static charges can pass Rife frequencies thru the body like RF does but at a simpler lower cost method. Static fields carry very little stored energy/ capacitive and can discharge/ flip polarity very fast.
The R VI units generate the same whole body response to frequencies at < 1 MHz using different energy type emitters. Simply pulse the R VI at the modulation frequency of the RF carrier and you'll have the same base frequency but with 3 different energy emitters to choose from.
