It's not the lightest machine at about 13 pounds, but it's portable enough to be usable by one person. You don't need technical training, either, so it's easy for security staff to use.

Whether or not you see the DroneGun in action is another matter. It's not FCC-certified as we write this, so you can't legally operate one in the US unless you're with the government. Provided it's approved, though, it could help take down drones at airports, protect soldiers against drone bombs and otherwise help in situations where it's simply not possible to get close.
