My name is Ken Presner. I am an independent researcher, inventor, author and health consultant. In 1989 I was paralyzed with Multiple Sclerosis. In 1994 I nearly died from Crohn's disease. I invented The Ultimate Zapper in 1996 inspired by Dr. Royal Rife and Dr. Hulda Clark. The Ultimate Zapper was vital to my recovery -- and has now become a family of five that rank as the world's best parasite zappers.

The Ultimate Healing Zappers

Innovative technology unique to The Ultimate Zappers creates by far the strongest and most effective zappers available. They also kill viruses, bacteria, mold, fungus and yeast far more effectively than any competing zapper. Discover for yourself why The Ultmate Zappers rank #1. Take advantage of the 3-month trial offer.

The Ultimate Zappers have helped thousands recover their health since 1996. The Archive speaks for itself with 1000 unsolicited testimonials -- versus a mere handful on other zapper sites. The Archive contains dozens of Miracle Testimonials, Cancer Testimonials and Lyme Testimonials that show how stunningly effective The Ultimate Zappers actually are.

After I got my life back I wrote My Recovery Protocol & Against All Odds. My books show I did not beat two incurable diseases and return to perfect health by accident.

From a UK therapist

Howard G.: I am a therapist with cutting edge equipment. The Ultimate Zapper is the most effective device I have used, ever. Strong statement? Yes, especially as I have 20,000 worth of healing equipment. I congratulate you on a simple device that will probably work on everyone. Oct. 3, 2012


The Archive is organized under 25 health categories and is searchable via Quick Search. The testimonials are numbered -- and they clearly speak for themselves.

QE2 is Extraordinary

Nick. N.: Your QE2 Ultimate Zapper is much more powerful than I expected ... after only 30 seconds of zapping my feces were full of white worms ... thank God I found you and your brilliantly strong healing device. I'll give you more details after at least three weeks. Anyway, your zapper is extraordinary. I love it. May 15, 2017

From a Medical Doctor

Dr. Mitchell H.: My wife and I had microscopic blood analysis showing toxoplasmosis, anemia, trichomonas, red blood cell damage & yeast. We zapped 10 times. New blood tests showed no parasites. The examiner was amazed. Incredibly fast results -- no drugs. We're very happy. Thanks for a safe, affordable way to get well. We really appreciate it. Feb 18, 2011


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 Ultimate Zapper 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, Jan. 29, 2011

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 ...


EIS Scanning (Electro Interstitial Scanning) is indisputable scientific proof of effectiveness for The Ultimate Zappers. You will not find a single piece of scientific evidence on any other zapper site to support their claims.

Below, have a look at the amazing scans 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 in the wings. 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.

These 3 scans were taken before zapping
Colored areas show abnormalities
1. Colon -- pale blue -- low cell activity.
2. Stomach and liver -- teal blue -- chronic inflammation.
3. Kidneys -- medium blue -- low activity of organ cells.
4. Heart -- navy blue -- hypoxia (low oxygen supply).
5. Heart -- pale blue -- low cell activity.
6. Heart -- yellow -- light inflammation.

The difference between The Ultimate Zappers and the competition is clear. The others showcase Bells & Whistles they call features but that contribute nothing to effectiveness -- carrying cases, belt clips, Lexan labels, sensors, beepers, low battery lights -- the list goes on & on. In fact, you have to look long and hard to find any competitor with more than 1 or 2 True Features.

The Ultimate Zappers showcase only the 12 True Features that deliver power and results. No Bells or Whistles. Extra features are added to the Premium Models for faster and deeper results. True Features = power = results. Relative Strength Charts and Zapper Comparison Charts prove The Utimate Zappers are head-and-shoulders above all the others.

Relative Strength Charts

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

Zapper Comparison Charts

Comparison Charts showcase the 12 True Features in a direct comparison between 30 competitors and The Ultimate Zappers. Again -- no contest. No wonder why Terminator and its clone, Longevity Zapper, recommend zapping around the clock. They are weak battery zappers.

The Ultimate Zappers are so powerful, zapping starts at only 10 seconds and many people stay at that level. There is no around-the-clock zapping (and no 20-minute breaks with the Premium Models). But, thankfully, the actual zapping feeling is gentle and relaxing. Many people zap at bedtime for a much better sleep.


What's the difference between the 5 models? Painstaking research, scientific innovation and extensive field testing contribute to the development of each model. Each is more than twice as powerful as its predecessor.


But there's  much more to the story. The 12 True Features create a powerful synergy -- a multiplifier effect -- with extra features added to the 3 Premium Models -- QE1plus & QE2version3 & QE3 -- that maximize power and optimize results. Synergy is the secret to their amazing success

So, moving up from SE to XEplus to QE1plus to QE2version3 to QE3, you can expect much faster results with progressively deeper penetration.

The Model Chart below is a quick-reference guide to the 5 models. It shows QE3 is 16x more powerful than SE. And SE is no weak cousin. It accounts for 50% of testimonials in The Archive because it has been with us since 1996. SE is The Original Ultimate Zapper. Click on Premium Models and Classic Models (above) for all the details.

Harmonics are a True Feature of The 5 Ultimate Zappers -- one of the keys to their power and effectiveness.

The Ultimate Zapper                           All Other Zappers

And some competitors  really like The Ultimate Zapper. Terminator's Don Croft endorsed it and David Etheredge of ParaZapper also endorsed it, clearly unwittingly, when he boldly declared that "it may be the best single frequency zapper" -- which simply means the best zapper according to Dr. Hulda Clark who invented the original parasite zapper.

Dr. Clark defined zappers as pulse generators that use a positive offset square wave and a single frequency to kill bacteria, yeast, fungus, mold and parasites that resonate at all frequencies. The exact definition of The 5 Ultimate Zappers. See the Professional Endorsements page.


The 5 Ultimate Zappers are easy to use. Here is the Instruction Manual. There are no buttons and no beepers. Just flip the switch and zap for 10 seconds for starters. And there is only 1 mode -- the healing mode.

The Satisfaction Guaranteed package with The 5 Ultimate Zappers is the best offered by any zapper -- including a lifetime warranty enjoyed by 1000s of satisfied customers in over 60 countries. People are so happy with the results that 99% keep their zapper after the trial. Why not give it a try for 3 months? You'll likely be very happy, too. The logo should actually say 99% Guaranteed.

My Recovery Protocol

email me for
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 -- both caused by "silver" fillings that are 50% mercury. Opportunistic parasites & other pathogens attracted to metal and chemical toxins create a chain of pathology. Breaking the chain led to my recovery.

The Big Dental Lie & The ADA lies thru their teeth.

The modalities in my book apply to all conditions, not only to "incurable" diseases caused by dental mercury. My book has helped many people recover their health by making informed choices -- using information in my book that The System does not provide. Why doesn't The System provide this information? Because illness is their meal ticket.

This photo is from the Minamata mercury disaster in Japan in 1956
I looked like this in 1989 -- paralyzed and bedridden with MS

Part 1 of My Recovery Protocol covers detoxification, including sources of toxicity, the chain of pathology, detoxification, specialized lab testing (not via The System, of course), 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 more about 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 is all about taking charge with information not available from The System.

Empowerment -- it's in our hands


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.

I looked like this in 1994 after Crohn's surgery
-- with my actual hospital ID wrist bands (right)

Against All Odds (275 pages) is the companion to My Recovery Protocol. It is the story of my recovery that ended in my 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 first causes serious diseases then stacks the odds against recovery. Read more about Against All Odds.
