How does a Stun Gun work?
A stun gun is an electrical self-defense device that uses high voltage to stop an attacker. Touching a person with the prongs on the stun gun quickly immobilizes the attacker. However, because the amperage is very low, no serious or permanent injury is inflicted.
The stun gun is designed to key into the nervous system. It dumps its energy into the muscles at a high pulse frequency that makes the muscles work very rapidly, but not efficiently. This rapid work cycle depletes blood sugar by converting it to lactic acid all in just seconds. The resulting energy loss makes it difficult to move and function. At the same time, the tiny neurological impulses that travel throughout the body to direct muscle movement are interrupted. This causes disorientation and loss of balance and leaves the attacker in a passive and confused condition for several minutes. Still, there is no significant effect on the heart and other organs.
As a general rule, a one-half second contact will repel and startle the attacker, giving some pain and muscle contraction. One to two seconds will cause muscle spasms and a dazed mental state. Over three seconds will cause loss of balance and muscle control, mental confusion and disorientation.
The stun gun is legal in most states. However, before you order one, please make sure they are legal where you live. You may check here first.
[color=red]The electrical shock that emits from the unit will not pass from the person being stunned to the person doing the stunning. The effect is localized only in the affected area and does not pass through the body. Even if you or the attacker are wet or standing in water, you will not get shocked.[/color] If you have any other questions about these devices, give us a call or send us an email.

how can this be?
i’ve always been told that if peoples hold hands,it would be the last in the chain to feel the shock…
another point is,how does this device generate such a shock from just 3 9V batteries???
