Very interesing - so how did the high voltage generator get used as an long range metal (gold) detector. It seems the high voltage circuit was only part of the total system. The unknown old parts have been identified as a high voltage generator. So did the doctor tell you how to use it as an LRL??
BTW - my wife has one of those electreat devices. She used it to restore badly burned hand back to normal condition.
She has used the the Electreat for many other nerve maladies and it does restore normal nerve conditions. The Russians did extensive testing of using high voltage low current in many medical situations and found that the HV does help restore and heal the body. The American drug cartel has been very effective in keeping many very good alternative treatments off the market in favor of using high priced drugs to cause more problems than they help.
