My name is Ken Presner. I am an independent researcher, inventor, writer and health consultant. I was paralyzed with MS in 1989 at age 40. I nearly died from Crohn's disease in 1994. I invented The Ultimate Zapper in 1996. It was vital to my recovery by killing parasites and breaking the chain of pathology. I did not beat 2 incurable diseases and return to perfect health by accident -- as Against All Odds and My Recovery Protocol show.

I'll give you more details after at least three weeks. Anyway, your zapper is extraordinary. I love it ... May 15, 2017

From an M.D.

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.

Karen Allen on YouTube

Actress Karen Allen starred with Harrison Ford in Steven Spielberg's Indiana Jones movies. Karen recovered from Lyme disease in 1 day using The Ultimate Zapper SE. She now uses XE. In Karen's interview and her Lyme Page she talks about her miraculous recovery and the recovery of "15 or 16 people" who also used her Ultimate Zapper for Lyme. Read 27 amazing Lyme Testimonials in The Archive -- 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]

SE & XE are the original Ultimate Zappers with 12 True features. SE has solid copper clips and XE is more powerful with gold-plated professional-grade Neutrik plugs. QE1plus is far more powerful, adding a Neodymium Magnet Array & Amethyst Crystal Matrix plus copper and steel handholds. QE2version3 is the most powerful Ultimate Zapper with an enhanced Magnet Array & Crystal Matrix plus 2 pairs of copper and steel handholds.

Other zappers boast an endless list of costly Bells & Whistles that do not create results: low battery lights, timers, sensors, wrist bands, digital read-outs, automatic cycles, automatic shut-offs, modes, panels, flashing lights, dials, buttons, boosters and beepers. The Ultimate Zapper has a no frills approach. You pay only for what creates results -- 12 True Features.


Advancing from SE to XE to QE1plus to QE2version3, expect faster and deeper results produced via the synergistic effect of their True Features. This synergy creates a powerful multiplifier effect. This is the secret to their success. QE1plus & QE2version3 have extra features that maximize power and optimize results.

Look over Comparison Charts that compare The 4 Ultimate Zappers with 30 competitors based on the 12 True Features. No other zapper comes close to the strength of The 4 Ultimate Zappers. It's no simply contest.


The EIS Page features dozens of scans of women and men with a variety of conditions before and after using The Ultimate Zapper. The scans are clear scientific proof of effectiveness for The Ultimate Zapper and are not offered by any other zapper. Below are EIS Scanning images of a male age 40 before and after using XE via Duration Zapping (30 minutes a day for 18 days).

EIS (Electro Interstitial Scan) was developed the US National Aeronautics & Space Administration (NASA) as cutting edge 3-D imaging and diagnostic technology. 1500+ medical doctors use EIS Scanning for patient diagnosis.

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.


These 3 scans were taken after zapping.
Grey areas show total normalization.


Dr. Jerry. L. Tennant, M.D., has written a series of books entitled Healing is Voltage. His work reinforces my 20 years of research into the link between The Ultimate Zapper's constant voltage and zapping results -- research that is incorporated in the design of SE, XE, QE1plus & QE2version3.

How does the competition feel about The Ultimate Zapper? Surprisingly, they love it. Don Croft of Terminator actually 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. She defined zappers as pulse generators that sweep all bacteria, yeast, fungus, mold and parasite frequencies using a single frequency with a positive offset square wave. That is the exact definition of The Ultimate Zapper.

But The Ultimate Zapper is light years ahead of the competition in terms of strength and effectiveness. This has inspired some makers to get creative. After ParaZapper endorsed The Ultimate Zapper he tried to clone it and take its name. Visitors are greeted by humor and shenanigans when they ...

add Against All Odds to your order

Against All Odds is the 275-page companion to My Recovery Protocol. It is the personal story of what I went through to get my life back -- paralysed with MS in 1989 and nearly dying from Crohn's disease in 1994. My book tells how I escaped a hopeless 7-year nightmare of blood, sweat and tears -- in spite of The Medical System.

Against All Odds is more than an account of my recovery. It also exposes the AMA and FDA colluding with the cunning ADA to create illness and profit from the results. Discovering that The Medical System is corrupt impelled me to fight back and search for a solution to the problems I was facing.

According to The Medical System I was facing a losing battle. They should know what they're talking about since they cause these diseases then stack the odds against recovery. But I ended up beating the odds and The Medical System. My book reveals how I accomplished this. Read more.

I wrote My Recovery Protocol after a 7-year life-and-death battle with two incurable diseases caused by mercury poisoning from "silver" fillings -- MS and Crohn's disease. The Big Lie is that "silver" fillings are actually 50% mercury. Mercury leaches 24/7 into organs, bodily systems and tissues. Dentists "place" mercury in our mouths with full legal sanction -- with devastating consequences. Dentists are in total denial.

The ADA Lies thru Their Teeth

Because studies show that everyone working in a dental office is mercury toxic. But you will never hear the M word from your doctor if you present symptoms of mercury poisoning. The Medical System makes sure doctors protect The System from legal liability. They never look for mercury -- the #1 neurotoxin on the planet and the most common toxin we are exposed to. There are many other metals and chemicals that also cause disease. My book addresses all toxic exposure. It has helped many recover from a wide variety of conditions caused by exposure to a variety of toxins. My book tells exactly what I did to recover my health and get my life back.

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

Mercury is the #1 neurotoxin on the planet. It causes childhood and adult neurological conditions. Scientific studies prove mercury causes cancer. By suppressing the immune system mercury causes candida and Lyme. Mercury poisons glands and organs causing diabetes, thyroid disease and heart disease. As it is excreted from the body mercury destroys the bowel.

The Medical System pours billions into research while totally ignoring the issue of mercury and other metal and chemical toxins as a possible cause of disease. Big Pharma controls The System. Instead of looking for toxins and thereby finding cures they "discover" drugs that generate massive profits.

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

The key to my recovery was breaking the chain of pathology by detoxifying mercury and other metals -- parallel with zapping to kill the parasites that are attracted to toxic metals. The disease process was thus reversed. I am living and healthy proof you can even recover from paralysis and near death from mercury poisoning in spite of The Medical System.

My Recovery Protocol contains 20 years of research that has helped many people recover their health. It will empower you to make informed choices. You will not get this information from The Medical System. Read more.

Many manufacturers call their devices "Hulda Clark zappers" when they are actually frequency generators. Frequency generators are much more complicated than zappers -- as this explains. Dr. Clark never sold any devices or endorsed any company. But she did warn about complex hit-and-miss frequency generators involving expensive syncrometer testing and diagnosis -- followed by multi-frequency treatments with generators using complicated frequency charts.

Frequency charts ...
the first of a long series

The Ultimate Zapper keeps things simple. There is no testing or diagnosis. There are no complicated treatments or charts to follow. The only surprise is the amazing results. All you need to know is how to flip a switch.


My site is a message of hope. I am an incurable optimist. You have to be to overcome 2 incurable diseases. I follow my mother's example. Here she is zapping at 90 after twice beating life-threatening cancer. She believed The Ultimate Zapper helped her live a longer and healthier life. Indeed, she kept her own home until she passed away just shy of 98. God bless her.
