Zappers are okay if they are low frequency and high powered. Therefore to have a real good chance ideally you would want a 12-18 volts model and a 15hz Frequency. Paddles are better as long as they aren't too large. The best method of Zapping would be to use a external Zapper for one week, then a Sputnik Pill till its removed, then external then sputnik etc. I personally prefer Blood Electrification but remember this only hits the spot its placed and the Blood via pulse points thanks to Dr Robert C Beck.
A good zapper would a Terminator with a 12-18v modification and external paddles. You would still have it strapped to the body for the mobious coil (scalar wave) penetration.
