"The chance of three successive misses doesn't drop in a linear fashion," TASER International CEO Rick Smith explains. "It drops exponentially. Three shots gives you a 99.2 percent success rate vs. 80 percent for one shot."
Another benefit of the X3 TASER is that officers can now engage up to three subjects without reloading. The cartridges can be fired in order, or the user can choose which cartridge to trigger out of the three. This gives the user the ability to load the X3 with both short-range and long-range cartridges and choose the cartridge type needed for each confrontation.
H Warning Arc While Loaded-The X3 gives the user two ways to end a confrontation without firing a cartridge. An officer can paint a suspect with the weapon's dual laser system and back him down. Better yet, the X3's new cartridge design shows the electricity arcing across the front of the TASER while it is loaded and the safety is off. This is designed to warn the subject that he is about to get zapped, so he'd better comply.
H Vastly Improved Intelligence and Safety Features-It would not be an exaggeration to say that the X3 is the smartest TASER ever. It features a Pulse Calibration System that measures the voltage and the charge of each pulse (like the X26, the X3 pulses 19 times per second) when the TASER is fired.
Smith says the optimal charge for effectiveness and safety is 70 microcoulombs. The X26 cannot adjust its pulse for effectiveness if the subject is wearing thick clothing; the X3 can.
