What's In A Name

The name stands for the Thomas A Swift Electric Rifle, an allusion to the weapon carried by the hero of early 20th century science fiction young adult novels.





Tasers fire two barbs (with quarter-inch fishhooks on the end) capable of producing 50,000-volt pulses into the targets' central nervous system.

The shock frazzles the body's electric signals, contracting muscles and incapacitating the target.Each individual shock lasts up to five seconds, at the discretion of the shooter, allowing police to gain control of chaotic situations.

Aimed by a laser sight, the two probes have a range of 21 feet and are tethered to the gun by lightly insulated wire. Both need to strike skin or clothing to be effective.



Fabric two inches thick or more, though, can render the jolt ineffective.

Tasers can also be used without the probes, by placing the guns end directly onto a suspect's skin, and firing.

The weapons also have small microprocessors inside them that record every time an office shoots them, and how long the shocks lasted.
