MZ5b from Maestro-Zapper

The MZ5b zapper of Maestro-Zapper has an extremely simple packaging, obviously to offer a very low

It comes without 9V battery or any electrode, but with 2 PDF big manuals.  He is described as “… the
smallest, lowest priced zapper, in the world, in the category of zappers run by a micro-controller”

Alligator clips permits the use any kind of electrodes.

Mechanical specs :

Automatic shut down (sleep function).
Program_2 : Name : 2.5kHz.  Sweep frequency using 33 different frequencies, between 2424Hz and 2522Hz.
75 scans per second, for a maximum of 3h09mn.
Rise time : 118nS without load, 71nS under load, giving about 3.5MHz cut off frequency at -3dB

Overall :
With so many functions, 2 main
frequencies, 2 automatic
programs and its denuded
packaging, this zapper is amazing,
even without a buzzer.  Can it be
effective with this small voltage?

At $28.00, where is the catch?

This low price, Its functions and
automatic sequences puts it in
the category of 1st zapper’s
users.  Its voltage at the lower
end of Dr Clark’s
recommendations (5 to 10V)
makes it acceptable for general,
routine use.

2010) $28.00US
=  Ideal for newcomers wanting
to try this technology with the
basic zapper’s effect (30kHz) or
frequency zapping (2.5kHz), or as
a backup zapper, or a traveler’s
zapper, due to its minuscule size.

similar results.

Maestro-Zapper comments on this "MZ5b" bench test :

=>  “At $32.00, where is the catch?”
The packaging and presentation of an electronic device (cabinet, escutcheon, geneeral packaging, …) very
often counts for more than half of the cost price. 
Quite often, the colored carton box of washable fabric soap cost more than the product inside!
Simplifying the presentation to the extreme leads to very low priced to the customer’s end.

This zapper (MZ5) puts the use of a micro-controller in a range of price otherwise unattainable..  This
zapper is intended as an incentive to an easy use and an easy access (price) to any first user.
Profit margin is so low, it makes potential retailers unhappy.

Add a buzzer, an appealing hand held case, a higher voltage, and you will end up with a more powerful
device (MZ6 style)… and with a price 3 to 4 times higher. 

=>  “The voltage is acceptable, but a few more volts would not hurt.”
For the general purpose use this device is intended, a reliable 5V is sufficient, as many happy users will
testify.  For more serious use, it request a longer session’s time. Those who have a sensitive skin, or are
afraid of electricity really appreciates this lower voltage, still efficient according to Dr Hulda Clark.

In the original zapper, the output voltage without load is a mere 8.0V with a new battery.
On the program_1 with 30kHz, this zapper is less powerful than the original one, despite a lower 806_Ohm
internal impedance, and about equal if a 6.5v battery's voltage is used.
With Program_2, 2.5kHz, 93% duty cycle is more powerful than the 30kHz, 55% Duty cycle.

30kHz with 7-20 automatic sequence to begin with, 2.5kHz continuous for more serious cases.
What else could we ask for…  If that is the case, look for the MZ3b

=>  “The transparent heat shrinkable sleeve  seems out of context.  Can it be improved?”
Initially, a transparent case, similar to USB packaging was in the drafting board, but initial quantity did not
justify the price of the plastic mold needed.   When quantity will be acceptable, a better solution will

=>  Numerous LED’s functions seems confusing at first.
Thanks God, only at first! With routine, you get used very quickly

will make a high number of odd

very long duty cycle of the
waveform (RC = 93.5%).

Certain Internet sites associate zapper and serious illness.
It is not our role to make such assertions. 

Illness does not interest us.

We leave it to the experts of the unhealthy states.
We are only interested to feel better, which is highly subjective, and to get rid of as much “invaders” who drain our resources, as possible.

These invaders, who live at our expense, we name them under the generic name of “parasites”.

We experience the influence of the zapper effect
on these parasites, on a hypothetical and empirical basis, which have nothing to do with medical or scientific rules.
