Everytime a taser goes off, it releases 500,000 volts of electricity. On Thursday Butte police officers learned how to use these tasers, but not by just practicing on dummies.
Each newly hired police and detention officers had to get hit with the painful tool.
Butte Silver Bow Detention Officer T.J. Carter said, "You feel the little barbs and a tiny pinch and then your whole body cramps up and you can't move and it just hurts."
Instructors said it's critical these officers know what it's like before they use it on a suspect or inmate.
Anthony Jurenik, a taser instructor with the department said, "They've got knowledge about it that's why they have to be tased to use it. Also, so they understand the effects of what it feels like."
When shot, the tasers release two electrified prongs that attach to the person's body.
The electricity triggers several muscle spasms causing the person to lose all control over their body.
Instructors said it is safer and more effective than pepper spray, but it still has its dangers.
"If the hand crosses where the barbs are, we call it being bit," Juernik said.
There's the chance that an officer could get shocked or the darts could hit the wrong spot. That's why they say it's important to have this training. So they know what they're doing and how it feels.
"So you don't overdo it and cause any harm to them because it really hurts. You don't want to hurt anyone else unintentionally," said Carter.
The department said more than 100 trainees have been tased. It is part of a day-long class on the safety and proper use of a taser.
