The MagZapperThe SOTA MP5

The MagZapper is a magnetic pulse generator similar to the MP5 made by SOTA Instruments. Both units are based on the original research which has been adopted and used by large numbers of people world-wide since the early 90's.

The SOTA MP5 is widely considered to be one of the best magnetic pulse generators available. In my opinion it is the best, without a doubt, and is a product I have personally used for years. When the MagZapper was introduced in early 2011 by Dr. Clark Research I wanted to know more about it, particularly the claims that it produced twice the capacity of the SOTA MP5.

What I found with the MagZapper was a reasonably well-made unit that, unfortunately, does NOT live up to its claims. Even worse, in my opinion, is the recommendation by the manufacturer to use the SOUTH POLE side of the wand to "stimulate" an area of the body. The exact wording from their instruction manual is:

"To stimulate an area, apply the S-Side (S = South Pole of the magnet) of the applicator directly to the skin."

The disturbing part about this statement is that it is widely recognized that South Pole energies do, indeed, stimulate an area, as in to "encourage growth." Why is this bad? Well, just consider for a second what you may be stimulating and encouraging to grow: bacteria, fungus, mold, cancer cells, etc.

I personally had the honor of speaking on the phone with Walter C. Rawls, Jr. in 2004 about the use of magnetic fields and their health benefits. Mr. Rawls and his partner, Albert Roy Davis, spent years researching magnetic fields and their influence on biological systems. They wrote numerous articles and books on the subject. Mr. Davis was the person who, in 1936, first discovered there was a difference between North and South pole energies. Mr. Davis was nominated for a Nobel Prize in Medical Physics in 1976. In other words, Davis and Rawls were unquestionable experts on the use of magnetic fields with the human body. You can read more of their accomplishments and truly outstanding contributions to mankind by clicking here.

The main thing I took away from my conversation with Walter Rawls, Jr. was to NEVER expose the body to South Pole energies for any length of time unless you were VERY sure about what you were doing. That advice has stuck with me ever since, which is why I can't advise anyone to use South Pole energies when using a magnetic pulse generator. There's simply too much uncertainty for most people to take the risk. A few minutes here and there are not going to cause any problems, but 20 minutes per session with multiple sessions is definitely too much in my personal opinion.

My second major issue with the MagZapper is the publicized comment that it has twice the capacity of the SOTA MP5. This statement is misleading in a big way. According to one reseller of the MagZapper:

"The Clark MagZapper has twice the capacity of the SOTA device!*, at almost the same price. * Total capacity of the built in capacitors is double that of the SOTA device."

What exactly is this saying? Well, the impression is that the MagZapper is twice as strong as the SOTA MP5 and in some way better or more effective. That is simply not the case. The actual technical specs from the manufacturer of the MagZapper state:

Technical data
Size basic unit: 210 mm x 155 mm x 52 mm
Size applicator: 250 mm x 75 mm x 28 mm
Maximum strength of pulse, measured with instrument FW Bell Gauss/Tesla Meter 5180
1 s (1 Hz) = 2.400 Gauss
2 s (0.5 Hz) = 3.000 Gauss
3 s (0.33 Hz) = 3.600 Gauss
4 s (0.25 Hz) = 4.500 Gauss
5 s (0.2 Hz) = 6.000 Gauss
Type of Signal: pulse
Frequency range: 0.2 Hz – 1 Hz
Power supply: DC 12 x 1.7 A = 22.4 W

The above info states that with a 5 second pulse the output strength of the MagZapper is 6,000 Gauss. Actual measurements on a production model showed an output of only about 5,000 Gauss. You can barely see the measurement of 5.09 in the picture below, which means an output of 5,090 Gauss:
5,000 Gauss at 5 second Pulses

At a 1 second pulse setting it actually does better than the stated 2,400 Gauss with a measurement of 2.96, or 2,960 Gauss:

1 second pulse measurement

Now for the interesting, and misleading, claim of twice the capacity. Unlike the SOTA MP5, the MagZapper uses two capacitors, each rated at 350 Volts and 560uF. I guess this is where they claim twice the capacity, because they use two capacitors instead of one. The problem is that the unit charges each capacitor to 330 volts but only fires one capacitor at a time, so it fires (pulses) one capacitor while the other is charging. This has no effect on the output of the MagZapper in any way whatsoever, which makes the claim "twice the capacity" completely misleading and strictly a marketing ploy..

My guess is the only reason two capacitors were used was in an attempt to extend the life of the capacitors, which are an off-the-shelf variety MXR series made by Rubycon. These capacitors are not intended for strobe/photoflash applications which generally produce numerous and frequent pulses, and they are not designed to take the long-term continuous charging/discharging that a magnetic pulse generator requires.

A best guess is that these capacitors will fail after a year or two of regular use, and sooner with heavy use.

How does this compare to the SOTA MP5, which only uses one capacitor? The capacitor used in the MP5 is custom made and is particularly suited for strobe/photoflash applications. It is rated to last 30,000,000 (yes, that's 30 million!) pulses and under normal usage can be expected to last 10 years at the very least.

Also, the production model of the SOTA MP5 has been routinely measured as having a maximum output of up to and around 7,000 Gauss, but the company conservatively rates it as having a 6,000 Gauss output. There is nothing misleading about the performance or life-expectancy of the MP5.

On a positive note, the circuit board and design of the MagZapper is decent and appears to be well made. The plastic enclosure with its very striking and bold lime green color choice could have been a bit higher quality, but it is really not that bad. The coil used by the MagZapper appears to be a direct clone of the coil used on the SOTA MP5 and seems to be decent.

The MagZapper does allow you to speed up the pulse rate to as fast as once per second, but this lowers the strength of the magnetic pulse by up to half, which effectively lowers its penetration into the body. This isn't necessarily a bad thing, but it does mean you don't get as much penetration and a weaker magnetic pulse, which does limit the benefits somewhat.

To summarize:
  • the MagZapper seems to be reasonably well made, but the actual Gauss output does not appear to be as claimed and is below the output of SOTA's MP5
  • there is a big question about the life expectancy of the particular capacitors used in the MagZapper and whether they were correctly chosen for use in a magnetic pulse generator application
  • the capacitors used will most likely severely limit the life expectancy of the MagZapper
  • the claim of "twice the capacity" is completely misleading and appears to be meant to confuse customers and imply that the MagZapper is stronger and more effective
  • the ability to speed up the pulses while lowering the output is of questionable value
  • Lime green may be fashionable in Europe, but I find it a bit too much for my taste
