I have an EMPI 330 PV for sale - Barely used. Original cost was over 950.00. I would like to get $380.00 for it, please contact me at widmerbecky@yahoo.com with any questions or offers.

This portable Neuromuscular Stimulation (NMES) device is a multi-function electrotherapy system, with the ability to function as a NMES, TENS, and High Volt Device. The 300PV offers all the flexibility and power of the larger, more costly tabletop “clinic” devices in a portable package that runs on rechargeable AA batteries. This makes it ideal for both clinic and home use.
The 300PV generates a low level electrical stimulus to cause muscle contraction. Commonly adjusted parameters are waveform, pulse rate, and the length of device operation (duty cycle).
