Officers will start testing the tool for free for 90 days beginning in January.
A training video put out by the company that makes it demonstrates how it works.
The device, called the "Bola-Wrap 100," fires a Kevlar cord that wraps around a person 10 to 25 feet away.
It's an alternative to firing a taser or a gun and may be particularly useful when dealing with mentally ill individuals.
The device will be distributed to 200 officers once they are trained.
