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???
You’re thinking about normal electric shocks, where the current passes from one contact, through your body, to the ground (earth).
For a stun gun (I’m guessing here), it’s the voltage difference between the two contacts that count, the current passes from one, through the baddy’s body to the other contact. Remember it’s the path of least resistance that it will take, so if the contacts are 6 inches apart (about half the size of the length of a willy), the current will go through that path. If you hold that person’s hand, but their hand is 2 feet away from the contacts, the current would not be interested in going through you.
The current will take the shortest path, that is it travels between the two electrodes of the stun gun. To have the current flow across your body it would need to flow to ground, which does not apply here.
Haven’t heard that one and at first glance it doesn’t make sense to me.
The voltage can be increased to virtually anything you like though the current will become smaller. The product of voltage and current, i.e. the power, will remain the same (ignoring losses): P (W) = U (V) * I (A)

With holding hands however or other electric shocks involving an earth, there is a possibility the current can pass through the heart and stop it.

ouch,that’s just began some brain damage in me head,someone please wipe the drool

not true in my experience… back in university someone had a crank driven generator and with a circle of about 15 people holding hands and the first and last in the chain holding the wires, everyone in the chain would feel the shock… I’m no expert, but that was my personal experience, YphysicsMV…
