BARNEGAT BAY - When a fishing boat went down in waters off Sandy Hook last week, the New Jersey State Police used special technology to locate the sunken vessel.

New Jersey state troopers often deploy this sonar technology when conducting water searches throughout the state. Similar technology was used during Superstorm Sandy and in the aftermath of the "Miracle on the Hudson."

"What's nice about this stuff is it doesn't get cold, doesn't need to drink or eat. In many cases we will send this down instead of a diver," says state police Sgt. Christopher Wozniak.

The devices create images using sound waves, and can see up to 50 feet on either side of the boats they are used on, much further than trained divers can.

State police say the sonar technology can also be used in the fight against terror as the cameras allow them to check piers underwater for any potential explosives.

Troopers say the devices are some of the most valuable technology they use.
