A&M has a similar device though it cannot be used in a sweeping motion. It looks like a long, fat wand, and fires a sphere of ionized gas. 1 shot per cartridge, holds 1 cartridge at a time, comes with 20 cartridges and a charging station. The charging station gets plugged into an outlet and three gas canisters. It uses a mixture of CO2, helium and neon. The cartridge has a small tank that holds the gas mixture and a capacitor for the electrical charge. At peak it delivers a charge of 300,000 volts at 1 billionth of an ampere. Recommended distance to target is 50 feet. The farther the gas sphere travels, the less charge delivered. In practice, I've seen it lay a fugitive out for just over 5 hours. $189, fairly cheap, an non-lethal (usually) alternative to a gun when force must be used.
Notes of caution:
Though listed as non-lethal force, if used on a person with a nerve disorder, a heart condition, or low body mass, it may produce a lethal charge. The idea is to incapacitate (temporarily) not kill, so if one does use it, you might end up with a consequence that was not forseen or desired.
May not be legal in all states/areas.
Some states/areas may require special liscensing/training.
Though it usually does not kill, there will be at the least, a brief moment of extreme pain for the individual shot with it. This may bother the conscience of some users.
Others feel free to add other possible warnings I may have left out.
