My name is Ken Presner. I am an independent researcher, inventor, author and health consultant with over 35 years of experience in electronics design, computer programming and the health supplement industry.

In 1989 I was paralyzed with Multiple Sclerosis. In 1994 I nearly died from Crohn's disease. My 2 books -- My Recovery Protocol & Against All Odds -- show I did not beat two incurable diseases and return to perfect health by accident. I invented The Ultimate Zapper in 1996. It was vital to my recovery and was quickly recognized by users as the most powerful and effective zapper available. It became the world's #1 seller.

The Ultimate Zapper
Lots of Proof -- No Claims

1. The Ultimate Zapper ranks #1 for effectiveness with 1000 testimonials in The Archive. This is 20 times more testimonials than any competitor. Thousands of people have used The Ultimate Zapper to overcome a wide variety of conditions since 1996. The Ultimate Zapper is also unique because all testimonials are certified unsolicited.

2. The Ultimate Zapper's #1 rank in the Testimonial Department is backed by countless testimonials posted on highly-respected health sites such as CureZone, CancerTutor, Soul Guidance and dozens of other health sites.

3. Professional Endorsements from around the world confirm that The Ultimate Zapper ranks #1 for superior technology and effectiveness.

4. This practitioner & this therapist & this customer are among dozens of people who have compared The Ultimate Zapper head-to-head with devices from other makers and attest to The Ultimate Zapper's superiority.

5. The Ultimate Zapper is the #1 ranked zapper for networking. It is the only zapper with a worldwide network of distributors.

6. The Ultimate Zapper ranks #1 for site links. Far more sites link to The Ultimate Zapper than to any other zapper site.

Premium Models
QE3 & QE2version3 & QE1plus

Classic Models

7. Innovative technology unique to The Ultimate Zapper is the secret to its #1 rank. No competitor comes even close to the technology that drives it.

8. Relative Strength Charts and detailed Comparison Charts confirm that The Ultimate Zapper ranks #1. The Charts clearly show its technology is light years ahead of 30 well-known competitors.

9. This Scientific Study is definitive proof of the superior effectiveness of The Ultimate Zapper and resoundingly supports what users have been reporting in The Archive for over 2 decades.

10. EIS 3-D Body Scanning is graphic scientific proof of effectiveness for The Ultimate Zapper -- the only zapper in the world backed by this amazing technology. Look over the large sampling from the data base with hundreds of patient scans before and after zapping with The Ultimate Zapper. EIS 3-D Body Scanning is cutting-edge technology used worldwide diagnostically by more than 1500 physicians.

11. There are only two devices in the world that create the powerfully therapeutic Electroporation Effect -- a device from Inovio Pharmaceuticals, Inc. (with FDA approval) and The Ultimate Zapper (with clinical proof). Electroporation potentiates herbs, vitamin and mineral supplements, medicines, chelators, colloidal silver, homeopathy and acupuncture. It is also a natural, non-pharmaceutical blood thinner that un-clumps sticky blood cells, as the photos at the above link show.

12. Scientific Evidence proving the superiority of The Ultimate Zapper's harmonics was submitted (unsolicited) by a European electronics expert, accompanied by oscilloscope views and detailed commentary. Harmonics are a vital feature contributing to The Ultimate Zapper's effectiveness.

13. The Ultimate Zapper ranks #1 for power -- hands down. While other zappers are glued to the Hulda Clark schedule of 20 minutes zapping x 3 with two 20-minute breaks, The Ultimate Zapper starts at 10 seconds -- and many people don't need more. And you zap only once with the Premium Models with no 20-minute breaks. By comparison, Coin Zappers like Terminator and Longevity Zapper ironically advertise how weak they are by telling users they need to zap for hours at a time.

14. Dr. Hulda Clark invented the first parasite zapper in 1993. Her research showed that zappers must produce at least 9 volts or more at all times to be therapeutically effective on the cellular level.

But all battery zappers discharge from 9 volts to 0. Not 1 maker mentions the subject of discharge and the inevitable loss of effectiveness. Claims are made for long-life batteries -- as though this solves the problem. But long life does not = high voltage. It just means more time is spent below 9 volts.

The Ultimate Zapper is powered by 9-volt and 12-volt AC adapters that convert to Direct Current -- guaranteeing constant high DC voltage with no drop-off -- which guarantees optimization of therapeutic results at all times.

15. Dr. Jerry. L. Tennant, M.D., has written a series of scientific books entitled Healing is Voltage. His research on voltage confirms Dr. Hulda Clark's decades of research -- and my 20 years of research into the direct link between The Ultimate Zapper's constant voltage and its healing effects. This technology is incorporated in the design of all 5 models.


EIS Scanning (Electro Interstitial Scanning) is graphic scientific proof of effectiveness for The Ultimate Zapper. You will not find anything like it on any other zapper site.

See the amazing scans (below) of a male age 40 before/after using XE. The EIS Page has dozens of scans of women and men with a variety of conditions before/after zapping -- with hundreds more in the data base. The results speak for themselves.

EIS Scanning was developed in France as cutting edge 3-D imaging and diagnostic technology. It is used worldwide by 1500+ medical doctors for fast, efficient and precise patient diagnosis. Read more.

QE1 -- Horrendous ... Painful

Mike D. I decided to get this more powerful model [QE1] to help a man out who has had shingles for five years ... The doctors told him there's nothing more they can do, and he's been in horrendous pain ever since ... Nothing else has worked for this man except your zapper. Thank you for such an excellent and effective product.

Sachiko K. My father is eighty six years old ... had a great pain in the left shoulder bone ... so painful that he was unable to walk ... After close examination of the CT scan the doctor said there are two shades in his left lung ... suspected cancer. He declined painful examinations (bronchoscopic examination and cytodiagnosis) ... and started to use QE1. He is now using it about five times a day, one minute at a time and the pain is suppressed. Thanks to The Ultmate Zapper he is now walking normally. Thank you very much.

XE -- Wonderful ... Tremendous

Michael S. I would like to thank you for your amazing journey and all the creative thinking and personal suffering you went through to produce your wonderful Zappers. In ten years our first zapper stopped several abscessed teeth infections and all that goes with that. I had pains in my prostate that grew and got steady to the point I knew I was getting cancer (I'm 62) I had no intentions of going to the Dr. and didn't need to. I sat on the handholds wet with sea salt, one under each upper thigh ... for about 5 x 1 hour sessions and the pain went -- came back 3 weeks later just a bit and I zapped another few hours. It's been about 5 years. The list goes on with Dengue and chikungunya etc. God Bless You.
Jul. 30, 2015

Dr. Mitchell H. My wife and I had blood analysis showing toxoplasmosis, yeast, fungus trichomonas ... We zapped 10 times [with model XE]. New blood tests showed no parasites. The examiner was amazed. No drugs needed & tremendous results. We're very happy. Thanks for a safe, affordable, non-toxic way to get well. We really appreciate it.

SE -- Ecstatic ... Dying

JoAnn P. I have been zapping [with model SE] for lupus and Lyme which at this point has been by far the BEST I have ever been!! I am ecstatic that the zapper makes me feel so much better. I am also preparing for the liver cleanse as well ...
Jul. 28, 2016

Olga D. My cat was dying & the veterinarian told me to pay to him $186 dollars to put her to sleep because my cat will die anyway. She cannot go to the bathroom, could not breath, vomiting, shaking and discoordinated. Since I bought your [model SE] zapper my cat now eats, plays, running like crazy around the house, almost well coordinated, and her breathing almost normal. I also found your zapper [helps] in combination with superficial electroacupuncture and treated successfully eczema, asthma, fibromyalgia ...

Karen Allen on YouTube

Actress Karen Allen starred with Harrison Ford in Steven Spielberg's Indiana Jones movies. Amazingly, Karen recovered from Lyme disease in one day after using SE. She now uses XE. In Karen's interview and on her Lyme Page she talks about her miraculous recovery and the recovery of "15 or 16 people" who borrowed her SE for their Lyme. The Archive includes 40 amazing Lyme Testimonials including Karen's.

Ken, thank you so much ...

Karen Allen. Ken, I never get sick at all anymore since I began using The Ultimate Zapper. Thank you so much for the part you play in getting it out into the world. It has had an incredible impact on me. All the best, Karen Allen.

karen2Karen Allen: "[after zapping 4 hours] ... I fell asleep ... I got up and I began to realize I felt dramatically different ... within about the next 48 hours all my Lyme symptoms had gone ... I was completely cured by this wonderful little machine ... I am a true believer in the wonders of [The Ultimate Zapper] ... it was one of those eureka moments in my life. I know from my own experience that this works. I have even administered it to 15 or 16 people. It has helped all of them ..."

The Ultimate Zapper                           All Other Zappers

Many professionals and experts worldwide have confirmed the #1 ranking of The Ultimate Zapper -- including electrical engineers, electronics experts, medical doctors, health experts, EIS scanning specialists, therapists, health practitioners, healers and dowsers.

Terminator and ParaZapper have even endorsed The Ultimate Zapper -- the latter unwittingly (he is now trying to take it back) by boldly declaring that "it may be the best single frequency zapper" -- which means the best according to Dr. Hulda Clark who invented the 1st zapper.

Dr. Clark defined zappers as pulse generators (as opposed to frequency generators) that use a positive offset square wave and a single frequency to kill bacteria, yeast, fungus, mold worms & parasites that resonate at all frequencies. This is the exact definition of The Ultimate Zapper. See the Professional Endorsements page.


There's a powerful difference between The Ultimate Zapper and competing zappers. A close look (below) reveals some of the weaknesses zapper makers try to hide. But they can't hide from Relative Strength Charts and Comparison Charts that show the truth via head-to-head comparisons with The Ultimate Zapper coming out head-and-shoulders above all others.

There's a BIG difference
between zappers and frequency generators

Dr. Hulda Clark invented the first zapper in 1993 -- the A6 battery zapper that she used in her research. But it had limited effectiveness with only 2 features, a square wave and a single frequency. Dr. Clark also wrote The Cure for All Cancers. But she died of cancer in 2009. With all due respect for Dr. Clark, please note there are dozens of Cancer Testimonials on this site.

Zapper technology is based on a single frequency -- as per Dr. Clark's discovery. Read why. Some zapper makers try to improve results by adding frequencies to the A6 zapper. The result is a frequency generator. There is a big difference between zappers and frequency generators. Dr. Clark stated, "sophisticated gizmos" that add frequencies do not transform zappers into more effective devices -- in spite of the claims.


The competition ... is still working on it

For those thinking seriously about choosing a frequency generator, The Ultimate Zapper is so effective it even outperforms $4,000 Rife frequency generators, as this practitioner & this therapist proved. But, since frequency generators are hit-and-miss, complicated and very expensive, Dr. Clark said that most people will opt for a zapper. This makes sense.

Read more about the frequency issue and why frequency is only one of many factors that contribute to effectiveness. It is features that determine how powerful and effective a zapper is -- not just a single feature. In fact, the reliance of the A6 on frequency alone was the reason for its weakness.

The Ultimate Zapper's success is based on unique technology embodied in its 12 True Features -- including the best single frequency, as per Dr. Clark's unpublished research, a frequency she ironically never used in her A6 zapper. Extra features are added to the 3 Premium Models. The True Features create a powerful synergy -- a multiplier effect. This is the secret to The Ultimate Zapper's success.

There's a BIG difference
between Bells & Whistles and True Features

Bells & Whistles are touted by many zapper makers as features. But they are obviously not True Features since they contribute nothing whatsoever to effectiveness: "automatic shut-off, beeper, carrying case, belt clip, push-button switches, sleek design, low battery sound alert, protection against incorrect battery installation, timer, straight cables, current sensing circuitry, LED display ... " The list of Non-Features is endless.

The Ultimate Zapper showcases only the 12 True Features that deliver power and results -- with no Bells or Whistles. Additional True Features in the Premium Models create even faster and deeper results. It is no surprise that Relative Strength Charts & Comparison Charts prove The Ultimate Zapper is light years ahead of the competition.

Relative Strength Charts

Relative Strength Charts show survey results after 2 years of field testing The Ultimate Zapper vs. 6 well-known competitors using a cumulative point system based on results obtained and the time required. No contest.

Comparison Charts

Comparison Charts -- no Bells or Whistles allowed -- showcase The Ultimate Zapper's 12 True Features in a head-to-head comparison with 30 competitors. Once again, no contest.

Here's the line-up of the 12 True Features -- with extra features added to the 3 Premium Models. There is not 1 Bell or Whistle in sight. Only the features that create power and effectiveness. No competitor comes even close to what The Ultimate Zapper offers. Read the details here.

The Competition
Lots of Claims -- No Proof

The Ultimate Zapper is the only zapper in the world that provides proof of effectiveness and preeminence -- while many makers offer up false claims, misleading assertions and disinformation disguised as proof.

The full story is in Zapperland, with some examples given below. Arthur Doerksen of AutoZap called Zapperland a scathing expose of the zapper industry. It is also an entertaining expose, told with a large dose of humor.

The Music

In the end, the facts demolish the credibility of zapper makers who are prepared to say and do anything to get ahead. Frankly, I can understand them putting their fingers in their ears when the music starts to play.

It's not easy ... facing the music

Dr. Clark Research Association

Scientologist David Amrein's "Association" is not an association. It is a company and he is the sole owner. He has no medical credentials but greets visitors to his site in a white medical gown. And he uses Dr. Clark's name without her consent, as do Terminator, ParaZapper, AutoZap and others.

David Amrein calls his shop "Dr. Clark's Shop". Dr. Clark invented the first zapper but she never had a shop. She never sold zappers. She stated: "There are other websites and companies using my name ... or selling products that claim to be approved by me ... I am not affiliated with, and have no control over, any other website or company ... no other website speaks for me ... I do not endorse any manufacturer ... ".

Furthermore, David Amrein's devices are not zappers but are frequency generators that require complicated and expensive add-ons in the form of smart keys and program drivers. He misleads people into thinking his devices are zappers and says they are made "according to Dr. Hulda Clark". This is false since Dr. Clark advised people to avoid frequency generators in favor of zappers. As noted above, there is a big difference between frequency generators and zappers.

Never mind. David Amrein finally got things sorted out -- by agreeing to a Federal Court Judgment related to fraudulent advertising & false medical claims -- and then fled to Switzerland from the US. He threatened to "get to" me when I uncovered the facts -- emailing me "I want to sue you". He never did, of course. Instead, he tried to shut down my site by intimidating my Internet Service Provider.

"Who says I'm not an association?"

The Coin Family

The Coin Family includes Terminator, Mini Silver Terminator & Longevity Zapper. They are marketed as convenient zappers but they are very weak cousins opposite The Ultimate Zapper because they have few true features as The Charts show. And their makers unwittingly admit they are weak by requiring users to zap for hours at a time. Serious burns are often the result. False explanations are offered up to try to explain away the problem. This creates a credibility issue for The Coin Family.


Some of the comments in this section
were written before Don Croft passed away.

There are detailed reports here & here about serious burns caused by Terminator. A certified Terminator seller posts this warning: "If your Terminator Zapper starts to sting, itch or zap your skin you MUST move it elsewhere as it can burn through the skin." Which is not easy since The Coin Family recommends all-night zapping.

And Don Croft himself also warns about burns -- in the fine print -- but then does a U-turn and calls them "unpleasant skin reactions", claiming they are caused by biological acidity, not by Terminator. If this were true he would surely offer proof. Does he offer any proof ? Nope. Because there is none.

The truth is that Terminator does in fact cause these burns -- from the coins being in close proximity. The short signal path creates 2 hot spots by focusing the current between the 2 coins.

The obvious proof is that thousands of acidic people zap with The Ultimate Zapper without any burns at all. Which proves that Terminator is a flawed design created with convenience in mind -- not safety. That Don Croft offers a false explanation for Terminator burns is lamentable.


"This picture was taken almost two years ago and the scars
have now faded but I think they will stay somewhat permanently
cause I can still easily see them."

Adding to this credibility issue, he claims Terminator "helps remove heavy metals". Sounds good. If he had any proof he would surely offer it. Does he offer any proof? Nope. Not even a whisper. There is no proof because zappers are not chelators (substances specifically designed to remove metals). The irony is that uncovered coin electrodes can actually cause copper toxicity.

On the other hand, The Ultimate Zapper's Electroporation Effect greatly enhances the effect of chelators -- the only zapper in the world that creates this powerful therapeutic effect.

Mini Silver Terminator

Everyone should educate themselves about Educate-Yourself. The site is run by Ken Adachi -- make that Peter Boudreau. Ken Adachi is his alias. Educate-Yourself looks like an educational site that markets the Mini Silver Terminator, a Terminator clone complete with burn warnings.

But Educate-Yourself is not what it appears. It is actually a disinformation front. Boudreau is a liar-for-hire who has slandered many people. In 2010 he called me "pathological" on his site. I consider myself fortunate. Since he is not a licenced practitioner but a paid disinformer he was able to provide this diagnosis free of charge.

Boudreau appears to be an emotional fellow because he often gets excited on his site. And when he does he shouts IN CAPITALS. Which is actually good since lower case is not very effective for GETTING ATTENTION -- which I imagine is what he wanted when he decided to published false information about my site and commit slander.

Peter Boudreau

Peter Boudreau is indeed a paid disinformer who uses an alias to hide his true identity. If he used his real name it would be easy for people to track him down and take legal action. So, he "borrowed" the name Ken Adachi from the deceased Canadian poet, to create a false face. His father who helps in his "educational" endeavors also uses the alias of a dead man.

Back in 2010 Peter Boudreau went to the trouble of devoting a whole page on his site to propagating false information about my site. It was nice of him to go to all the trouble. But what was all the commotion about? His page focused on name calling, a free psychiatric diagnosis, and false information about the technical terms I use on my site -- "pulses and duty cycles" -- in an obvious attempt to sow mistrust.

Well ... let's do an Educate-Yourself thing here. As though Peter Boudreau didn't know ... in the world of electronics the technical term for zappers is pulse generators. So, it should be no surprise that pulse generators emit pulses. And in the world of electronics, another word for an electronic pulse is a duty cycle -- which anyone can find by doing a Google search.

Well ... it's clear that Peter Boudreau's discussion of electronic terms was simply an exercise in disinformation -- a cunning ploy by a liar-for-hire paid to libel targeted websites and slander their owners -- while appearing sanctimoniously educational. Paid to disinform? Paid to libel and slander? By whom? The answer is shocking.

By COINTELPRO. Peter Boudreau has been linked to COINTELPRO here where they explain that his "intention [is] to administer public confusion by deception". Furthermore, he "serves as the main propaganda mill for the COINTELPRO in the "alternative media" arena". Furthermore, federal whistleblower Stew Webb has blown the whistle on him & his accomplice family. And Peter Boudreau has been exposed as a total fraud here.

Welcome to Educate-Yourself
I'm (not the real) Ken Adachi ... how can I help (disinform) you?

As though all this weren't enough ... Peter Boudreau does his best to evade pursuers by changing his address frequently and he only accepts payment via a "special" tax avoidance donation payment scheme. Well ... so much for Mr. Educate-Yourself Adachi -- electronics authority & amateur psychiatrist -- and COINTELPRO disinformation agent.

Longevity Zapper

David Wolfe wanted to enter the zapper market but he knows zip-dee-do about electronics. He came up with the perfect solution: hire someone to create a zapper while making it look like he created it himself. Well ... the best they could come up with was a Terminator clone -- with burn warnings -- no free trial -- a 1-year limited warranty -- and no returns accepted.

But knowing zip-dee-do has not prevented David Wolfe from pretending he is an electronics expert -- making it all up off the top of his head in front of unaware audiences about "tight electronics" and the "up-down wave" and other fictional (and laughable) terms that do not exist in electronics.

He also claims Longevity Zapper is "designed to help the immune system". If he had proof he would surely offer it. Does he offer any proof? Nope. Not even a whisper. There's a lot more about David Wolfe in Zapperland.

Someone familiar
... is pulling the wool over our eyes.


Steve Coffman has a looong list of claims for Thundervolt & Body Tester. Here's what a customer who used them in a head-to-head comparison with and The Ultimate Zapper had to say.

Pamela S. I purchased the Thundervolt and also bought his Body Tester where you get a reading when you hold hand holds and step on foot pads. [It] shows energetically how you are doing ... I did a test with Thundervolt a couple times and noticed my reading went down! Not up! Then used your Zapper ... guess what, my number went up. So, oddly, this man's invention is showing me to use YOUR zapper!
Feb 17, 2017

Steve Coffman also claims "Our handhold device transmits safe low-voltage pulses ... [that] nullify the threat of pollutants in those attributes by wiping out free radicals." The threat of pollutants in those attributes? Attributes? What attributes? Looks like the English language just took a hit here. Does anyone out there have a gobbledygook meter?

How about nullify pollutants by wiping out free radicals? Wow. Wouldn't that be great? If he had proof he would surely offer it. Does he offer any proof? Nope. Not even a whisper. Because it's pseudo-scientific nonsense made up off the top of his head.

No thunder in the forecast.
Just drizzle.

Steve Coffman also claims Thundervolt blocks radio frequency radiation from Smart Meters -- without any radiation shielding. Wow. If he had proof he would surely offer it. Does he offer any proof? Nope. Not even a whisper. Because there is none. It's pure fiction.

"Zapping has been done for 100 years ..."? He forgot to do a fact check. Dr. Hulda Clark invented the first zapper in 1993. Facts? Who needs facts when you can make it up. It's just one thing after another with Thundervolt.


David Etheredge claims that adding frequencies to ParaZapper improves results. Sounds good. If he had proof he would surely offer it. Does he offer any proof? Nope. Not even a whisper -- no comparative testing -- nothing. The proof came from Dr. Clark who proved that one frequency kills all and that adding frequencies ... accomplishes nothing at all. Which some makers choose to ignore, including ParaZapper.

It's no surprise his new models are complicated, feature-poor, hit-and-miss frequency generators. Furthermore, since they use only a partial list of Rife frequencies they are actually truncated Rife frequency generators.

But David Etheredge calls them Hulda Clark Frequency Generator Zappers and declares -- with marketing in mind, of course -- that you can have it both ways. But Dr. Clark proved that you can't have it both ways. Because frequency generators are not zappers. Here's why.

After all the fanfare, the only thing ParaZapper has to show for itself is weak performance in the Comparison Charts and a dribble of testimonials. This is interesting since David Etheredge boldly has declared that I must have made up The Archive with 1000 Testimonials -- including that of actress Karen Allen.

In an effort to outdo himself he then boldly declared I am a shade tree mechanic -- asserting The Ultimate Zapper is "cheaply made". He forgot to do a fact check. He also claims The Ultimate Zapper "is not microprocessor based". He forgot to do a fact check. Facts? Who needs facts when you can make it up.

According to David Etheredge, The Ultimate Zapper is such a poor device ... that he turned around and tried (unsuccessfully) to clone it and actually took its name for his new UZ model. Wow. I must be some shade tree mechanic to deserve all this attention -- from someone who was caught falsifying his credentials.

Well ... it's clear some competitors will say and do anything to get ahead. Discover a lot more about David Etheredge in Zapperland.

David Etheredge's Testimonial Nightmare


Some of the comments in this section
were written before Arthur Doerksen passed away.

Arthur Doerksen claims his Zappicator "can neutralize benzene and other toxins magnetically". Sounds good. If he had proof he would surely offer it. Any proof? Nope. Not even a whisper -- no lab testing -- nothing at all. He also claims his "Wellness System" and 5 minutes of zapping with AutoZap "help boost the immune system to beat cancer". Sounds good, but obviously (and sadly) untrue. He died of cancer in 2016.

A serious claim -- with no proof

Mark W. Doerksen's Autozap5 uses a plastic in the wrist straps that conducts electricity ... Sadly, the good news stops there ... it looks lousy on a scope [an oscilloscope] and the batteries drop off quickly after 6 sessions ...

I'd rather have a hand assembled analog zapper [The Ultimate Zapper] with no bells and whistles that runs off of an AC adaptor than anything else. I've been using mine since 2015 and have had nothing but good results for myself and my elderly parents. I'm excited ... on the verge of the best 50th birthday present I can imagine! [his purchase of QE2]

Thank you again for sticking to your guns and always pushing beyond the "Clark Rules" and giving the world affordable, top-notch zappers that stand in a league all of their own.

The Best Zapper

Some of the comments in this section
were written before Arthur Doerksen of AutoZap passed away.

Please note

The zapper known as THE ZAPPER PERSONALLY APPROVED BY DR HULDA CLARK does not claim to be the best zapper. But the heading is misleading. It appears to be a copy of Dr. Clark's A6 zapper, but it was not personally approved by Dr. Clark. It could not have been. She died in 2009 before this zapper existed. In any case, as noted above, Dr. Clark never approved or endorsed any zapper.

The best

But many zapper makers do indeed call their devices The Best Zapper. What evidence do they present to back the claim? Nothing but Smoke & Mirrors -- opposite a mountain of evidence backing The Ultimate Zapper.


The best zapper? David Etheredge of ParaZapper goes one better. He calls ParaZapper "definitely the best". Very impressive. How does he back up the claim? He goes all out by providing the most solid evidence he has -- "The Best Comparison Chart". Sounds great.

The only problem is there is only 1 zapper in the chart -- ParaZapper. Which actually makes his chart "The Best Non-Comparison Chart". When you look at the Comparison Charts with ParaZapper and 30 other zappers going head-to-head with The Ultimate Zapper using only True Features, it is clear that playing it safe was a wise move by ParaZapper.


Steve Coffman calls Thundervolt the best zapper. Given its track record (above) Thundervolt has a looong way to go. Here is the basis for his "best zapper" claim.

"First: Dual waveforms; opposing energies crush pathogens" -- without a shred of proof. There is none. In fact, Dr. Clark who invented the first zapper in 1993 proved that zapper technology is based on a single wave form -- a positive offset square wave. And nothing more.

"Second: Interchangeable & swappable handholds and footpads" that allow 24 swaps. Well ... you can do all the swapping you like with The Ultimate Zapper. But swapping is not a True Feature. It is simply a fine-tuning option.

"Third: Body Tester numerically verifies effectiveness and gain in body power". That's presuming quite a lot. Verifies effectiveness? Gain in body power? Please note the failure of Thundervolt (above) in a head-to-head comparison with The Ultimate Zapper where the latter came out on top. The Body Tester qualifies as a feature that contributes to effectiveness? Wow. Really?

Steve Coffman's best zapper claim is clearly a table without legs. This has not prevented him from creating a very long list of claims for Thundervolt. As for backing up the claims? Not a shred of evidence is offered -- except for a dribble of 14 testimonials.


Arthur Doerksen's site is called bestzapper.com. The site still makes cancer claims for AutoZap in spite of the fact that Arthur died of cancer in 2016. Arthur's son now runs the site but has yet to announce his father's passing.

The AutoZap Comparison Chart includes The Ultimate Zapper. However, 5 out of 6 of his "features" are not True Features but are Bells & Whistles. For example, he says that "rugged construction" is a feature -- then says The Ultimate Zapper does not qualify. He obviously did not read this.

His chart also says The Ultimate Zapper has "no constant output voltage". I guess he forgot to do a fact check. The truth is the exact opposite. Now, take a look at the Comparison Charts on this site -- based on hard facts not on Bells & Whistles or false information. The hard facts show that competing zappers are very weak -- including ParaZapper and AutoZap -- and the Charts show precisely why.


The Ultimate Zapper has no buttons and no beepers. And there is only one mode -- the healing mode. Just flip the switch and zap for 10 seconds for starters. Here is the Instruction Manual.

My Recovery Protocol

Includes a free copy of
My Cancer Protocol
My Prostate Cancer Protocol


My Recovery Protocol (230 pages) describes the details of all the modalities that led to my recovery from 2 incurable diaseses -- Multiple Sclerosis and Crohn's disease -- caused by silver amalgam fillings that are 50% mercury -- the #1 neurotoxin on the planet. Wonder why the ADA forced dentists to use mercury fillings? They owned the 2 patents. No surprise -- The Medical System continues to ignore the fact that the symptoms of MS are identical to mercury poisoning. They are all in bed together.

The Big Dental Lie & The ADA Lies

The information in my book applies to all conditions, not only "incurable" diseases caused by "silver" fillings. Parasites and other pathogens attracted to metal and chemical toxins create a chain of pathology. Breaking the chain led to my recovery. My book has helped many people recover their health.

Part 1 of My Recovery Protocol covers detoxification, including sources of toxicity, the chain of pathology, detoxification, specialized lab testing (not via The System), test analysis/ interpretation, and a long list of "alternative" modalities discussed in detail, including parasite killing.

Part 2 of My Recovery Protocol covers rebuilding and revitalization, and the specific factors that consolidate recovery and create a healthy life.

Read My Recovery Protocol to discover the therapeutic steps I took to overcome 2 incurable diseases. My book has empowered people to overcome many conditions by making truly informed choices. It's all about taking charge. Read more about My Recovery Protocol.

Against All Odds

After being poisoned by mercury fillings, I went from paralysis with MS in 1989 to near death with Crohn's disease in 1994. Over a period of 7 years I clawed my way out, escaped the nightmare and returned to perfect health.

Against All Odds (275 pages) is the companion to My Recovery Protocol. It is the personal story of my recovery that ended in beating the odds -- and The System. I tell it exactly like it was -- including the blood, sweat and tears -- and the shocking truth about how The System actually causes disease then stacks the odds against recovery. Read more about Against All Odds.


Arthur Doerksen of AutoZap characterized Zapperland as "a scathing review" of the zapper industry. It exposes the sad, humorous and often absurd goings-on with Terminator, Mini Silver Terminator, Thundervolt, ParaZapper, Longevity Zapper, Dr. Clark Research Association & AutoZap.
