A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft, and a variable-shaped pickup coil. When the coil nears metal, the control box signals its presence with a ...
The magnetic anomaly from a submarine is usually very small. One source estimates that it is only about 0.2 nT at a distance of 600 m. [5] Another source estimates that a 100 m long and 10 m wide submarine would produce a magnetic flux of 13.33 nT at 500 m, 1.65 nT at 1 km and 0.01 nT at 5 km. [6] To reduce interference from electrical equipment or metal in the fuselage of the aircraft, the ...
Public safety diving team members bring in a casualty. Controlling an underwater search from the jetty. Underwater search and recovery is the process of locating and recovering underwater objects, often by divers, [1] but also by the use of submersibles, remotely operated vehicles and electronic equipment on surface vessels.

For the 2023 series, LEWT instituted some measures to prevent further cheating like what Cominsky and Runyan had done. All the top five finishing teams in each tournament will have their fish physically inspected, including possibly being cut open, and a metal detector will be available. Lie detectors will remain in use. [3] [12]
Of 3D-printed weapons, Rounds has said, "This is a new technology which you're not going to put back into the bottle. It is there." He has suggested creating and using new technologies, such as metal detectors that can also recognize plastic, in schools, airports and other public places. [33]
