The Coast Guard says it will begin using a new non-lethal signaling and warning device to enforce security zones in Hawaii's ports, waterways and coastal waters.
The LA51 is a 12-gauge military shotgun.
A Coast Guard video demonstrating the device shows a guardsman firing the shotgun in the distance in front of a boat on the verge of veering into a security zone. The people on the boat hear a pop and see a flash and smoke in the distance.
The Coast Guard said Wednesday the device is safer than the M16 tracer round it currently uses. It also gives off a bigger flash and sound.
It says Department of Defense weapons testing shows there is little risk of the LA51 causing significant injury.
