THE VOLTAGE MYTH
Be an Informed Buyer
The electronic stun device market is permeated with claims of extremely high voltages.
Unfortunately, most of these claims have little basis in reality. As you can see in the table below
from an independent published source,' the advertised voltage of most stun devices is greatly
exaggerated.

As you can see, only the Nova Spirit and AIR TASER advertise the actual voltage. The
AIR TASER has the highest, measurable, real voltage of any stun device on the market.
In reality, voltage tells you how far the spark will jump - and how much clothing the stun
device can penetrate if the spark must jump through fabric. This is the only true benefit from
higher voltage (amperage and power determine how strong the pulse feels).
In order to measure the peak voltage of a stun device, simply measure the distance that
the spark 'jumps' when you activate the stun gun into the air (measure from the two points
where the spark starts and stops). The rule of thumb is 30,000 Volts per inch. For example,
the maximum voltage of the stun gun below is 0,3 inches x 30,000 Volts/inch = 9,000 Volts.

Do Not Measure Here

Remember, the voltage is measured where the spark actually jumps, not from the
forward electrodes. Measure the length of the actual spark itself.
Again, there is much confusion about voltage. Voltage claims are usually not accurate.
However, calculating the length of the spark (and the voltage) will tell you how much clothing a
spark will penetrate. The best test for effectiveness is to look for the T-Wave™ trademark and
to test the unit to make sure it is built with quality and survivability.
