When And How To Use Stun Guns

What's the proper way to use a stun gun? The self-defense device has been in the news recently first as an attack device and second to subdue patient in a hospital.
For the latter, 151 hospitals in the United States are using these personal protection instruments as a security measure.
When patients get out of control and appear as if they could be a threat to doctors, nurses, and staff, the device controls the patient.
Nevertheless, stun guns are legally considered a personal protection device, aside from the use at hospitals.
But like other personal protection devices like pepper spray and mace, knowing how to use the device is the difference between protecting yourself and getting away from the situation and having to protection against your attacker.
A general rule for using stun guns is being familiar with the device.
Although commonsense, knowing how to use the device doesn't mean putting it into action on just anyone.
First, once you've purchased such a personal protection device, familiarize yourself with its parts.
The most crucial are the test and contact probes and the on/off switch.
Knowing their location and how to use them prepares you for an emergency.
Instead of fumbling, use the device with confidence.
Once you're familiar with the general format, create a plan for using it.
This is a combination of activating the device - locating the on/off switch and turning it on as quickly as possible - and knowing where to aim on the attacker.
In general, aiming for the torso is far more effective than an extremity, as the effect of the stun gun will be far more pervasive on the attacker.
Additionally, find a soft spot, instead of one near a bone, to aim.
When stun guns are used, simply touching the attacker with one is not sufficient.
The device needs to touch the attacker at an appropriate point for three seconds or more, which will leave the attacker stunned for roughly 15 minutes.
