Bipolar Speculum for estim

I made a bipolar speculum by insulating the two blades. This was east -- there were only 2 contact points on the handle and there was the screw. Both could be easily isolated. I then used my TENS as the source of current. Worked perfectly. Another current source, more powerful than TENS is the earphone plug on a a battery powered boombox.

Never use any source that plugs into the household current (mains) and never pass the current across the chest or near the heart -- it can send the heart into arrhythmia.

Good information and suggestions Good finger. Thank you.
