Most of them use the original X-26L, but there's a new model now with upgraded features.
Steve Tuttle with Taser International gave FOX 10 a sneak peek at the new smart weapon.
It's an upgrade to the original which only gave limited information to the user like; time, data, and duration of use.
"How many pulses per second are we getting? Were we getting any resistance on any of those individual settings? What were the engineering logs reporting back," said Steve Tuttle.
A quick glance at the screen and you see the device gives the battery strength and the type of cartridges in the Taser.
"It also gives you error codes so it can fix itself like you need more firmware updates, or you need to get a major fault looked at, but go ahead and use it, or if it's a serious error then just go ahead and don't use it," said Tuttle.
One of the main differences you'll notice between the original Taser and the new version are the number of cartridges, this is the original taser it has one cartridge, and the new one has dual smart cartridges.
"You now have the dual-shock capability, we've never had that before so in the event that you miss you have a built-in backup," he said.
A back up for officers and anyone else using a taser to defend themselves.
Phoenix and Gilbert Police, and the Pinal County Sheriff's Office are all using the new device now.
