Taser was invented by Jack cover in 1974. He was a researcher in Nasa. The Taser works on the principle of Electro Muscular Disruption technique. It generally stimulates our motor and sensory nerves which leads to muscle contraction. Stun guns and other self defense products have less effect on high pain tolerance people like drunkers and
The evolution of Stun guns comprises of an interesting idea. The idea was to stun people without any instinct to kill them.Stun gun is a self defense product that uses electric voltage to deal with the attacker. when an attacker comes in contact with stun gun prongs he gets temporarily affected. The current produced by stun guns is of low amperes that is why the person is affected for a small time and the effects are not very serious. Stun guns are available in a wide range of styles. the choice is generally based on individual preference. Higher the voltage of stun guns higher will be the impact. So the people generally wants Stun guns of higher voltage. But their is a disadvantage with high voltage Stun guns. These are very heavy and difficult to carry and use. But as we know that necessity is the mother of invention. Because of people's demand higher voltage stun guns are also available which can be easily fit in cigarette case.
The popular stun guns available in market are:
Stun master gun: These are guns of high quality .These are less expensive and are available in 100,000 to 300,00 volts range. Thus these guns are preferred by persons who wants safety at reasonable prices. This model of Stun gun can be used for both animal and human attackers.
Z- force Stun guns. These guns are very slim in appearance and thus can be easily hold by person with short palms. Because of this reason these guns are mainly used by women. The voltage range of these guns is 100,00 to 300,00 volts. You have to touch the attacker with these guns for avery small fraction of time. After this the attacker will loose his balance and will fall in confusion or get stunned.
Cell phone Stun guns: These guns completely disguises the attacker with its shape. These are available in 800,000 to 950,000 voltage range.
Runt stun guns: These guns are very small in size and can be gripped easily. These guns offers a voltage range of 350,000 to 600,000 which is enough to stop an attacker. this gun is only 2.5 inches in height.
Hot shot Stun guns: These guns are 3 inches tall and comes in a voltage range of 975,000 volts. These guns appearance is like a handheld mobile device.
Small fry stun guns. These guns are the newest in market. These are also known as mini guns because they are so small to be easily fit in cigarette packets.
The idea behind the evolution of stun guns and taser gun was to shock or stun people without any intention of killing them. These self defence products passes electric charge through the body of attacker.
