Stun Gun Operation and Design
Stun guns are small hand-held devices with two prongs (on top of the device) that generate an electric arc. It is activated by a button on the side of the device. Technically, it's not a "gun" at all because it fires no projectiles. Stun guns have more in common with cattle prods that similarly deliver an electric shock through contact.
The Stun Gun Disadvantage
The greatest disadvantage of a stun gun is that you must be in close proximity with your attacker to use it. A stun gun's advantage is its intimidation factor. When activated, an electric arc forms between the two prongs accompanied by a loud crackle. This display alone often dissuades attackers from pursuing further action.
Taser Operation and Design
Tasers are designed and operate like handguns and fire electrical probes (connected to the Taser by insulated wire). Tasers can effectively engage targets at distances up to 35 feet and use compressed nitrogen to deliver the probes to the target.
The Tazer Advantage
The Taser's greatest advantage is its effective range. Unlike a stun gun, which forces you into the precarious position of being in physical contact with your attacker, the Taser allows you to incapacitate your attacker before he is close enough to cause you physical harm.
Legal Considerations
The legal use of stun guns and Tasers for personal protection varies by federal, state and local laws. Additionally, even though these devices are nonlethal, the law requires justification of use. Check your local laws before purchasing a stun gun or Taser.
