This gun can stop small rogue drones without destroying them

We've seen a couple of brute force anti-drone devices designed to snatch the tiny machines out of the sky, but Battelle's DroneDefender is one of the first to do it with an invisible beam delivered in an ultraportable, gun-like form.

The device uses radio control frequency disruption to halt and bring down drones in a way that keeps the drone intact while preventing it from setting off any kind of self-destruct sequence.
That last point is important because small drones are increasingly being used for aerial surveillance. In the case of industrial espionage, the ability to snag a drone intact in order to investigate its source could be vital.
Capable of five hours of continuous use, the device has a range of 400 meters and jams ISM bands (radio frequencies reserved for industrial, scientific and medical devices) and GPS signals. A look at a brief video demonstration (below) shows a user targeting and bringing down a small drone with ease, just outside of what looks like a guarded facility.
