Clark Zappers

Extreme Zapper $90
http://www.dragonfly75.com/eng/EZ.html
Features: frequency selection of 30KHz or 2500Hz, 12 volt peak output, 50% duty cycle, positive offset waveform, guaranteed squareness of waveform when connected to patient (essential for effectiveness which is proven by lab tests), "Power" light (indicates sufficient battery power) and "Out" light indicating that output current is flowing to user correctly.


Terminator II Zapper $124
http://www.terminator2zapper.com/
Features: A zapper that has "orgone material" (although Wilhelm Reich never referred to any orgone material since orgone is pure energy. Supposedly orgonite can transform negative orgone into positive.), Neodynium magnet (supposedly to increase the energy from the fictitious orgone material), Mobius Coil (supposedly produces some kind of magical energy field), Natural Crystal. "Electrodes" are two copper pads for contact on the body. Problem with this is a very limited effective treatment area. See drawing below.

Frequencies: 15 Hz.
Electrical current output: 5 milliamps! (Ha! I guarantee you that no one on this planet can receive 5 milliamps of current at 15Hz without pain. This is proof that this guy is a New-Age space case that should get back on his meds and stop talking nonsense for gullible people to believe.)
Conclusion: This is a device for gullible people. It is a smogde-podge of New-Age trinkets all wrapped up in one device. Wear it around your neck if you want to "feel good". If you want a zapper that really works then buy mine.

The Ultimate Zapper $190
http://zap.intergate.ca/
Features: 80% duty cycle, 10.5 volts peak switched DC, 2500 hertz frequency
Exagerated Claims: zapper also does blood electrification (pure baloney), zapper increases effectiveness of medicines taken by electroporation (although scientific literature says electroporation only happens at frequencies below 100 hertz and at voltages hundreds of times higher than what this zapper outputs), zapper only kills bad bacteria and leaves the good bacteria alone (more pure baloney)

VariZapper $294
http://www.drclark.com/pictures/VariZapper_Gammatext_en.htm
Features: no output frequency listed, needs Program Driver Cards for other Clark frequencies, digital display, outputs to wrist bands
Conclusion: Without the essential technical information no assessment of effectiveness can be made. It can only be assumed that the output is traditional (5v peak, 30KHz, current limited output which looses the squareness of the waveform when in contact with patient which looses effectiveness)

Zapper Digital LCD $299
http://www.huldaclarkzappers.com/php2/index.php
Features: adjustable from 1Hz to 1MHz, 4.5-5 volt peak output of switched DC, digital frequency display, outputs to two wrist straps, can run any single frequency or sweep thru a range of frequencies
Conclusion: This would be a good unit to experiment with different frequencies but it's low output voltage of 5 volts greatly limits its effectiveness when using it to kill microbes.


Auto-Zap 5 and FreeCoil SuperZappicator $419
www.bestzapper.com
Features: 2500 hertz frequency output, 10 volt DC peak output, output to wristbands, 5 preset treatment progams
Output waveform is "classic Clark" in that it is not a pure squarewave when connected to the patient. They are so falsely bold as to claim the non-stablized waveform from the old Clark design is more effective. Look at the research proving how wrong they are at http://www.dragonfly75.com/eng/Medikzap.doc. They even wrongly claim that the waveform limiting resistor is necessary to prevent "tissue damage" by excess current although the Extreme Zapper produces more voltage/current and still outputs 25 times less current than what is necessary to cause the slightest amount of skin damage.

FreeCoil SuperZappicator
They claim its "north pole signal" reaches 12 inches from device. (not possible for a low powered electromagnet. My OMF Generator can't be effective that far although it is powered by 3000 volts.)
They say it is an "8-magnet version" which explains how it can reach 12 inches. But here's the catch; regular magnetic fields from magnets don't fight microbes. There is no research anywhere proving they do. But there is research showing oscillating magnetic fields and pulsed magnetic fields do. The magnets just reduce inflammation which can lead people to think it is fighting the infection. A nice con.
Conclusion: Their zapper is a one-frequency device with less output power than mine and a non-squarewave output. Their Zappicator is a pure New Age con, an overpriced set of magnets. To buy high powered magnets for a low price go to http://www.wondermagnet.com
