Sonar
SOund Navigation And Ranging
NIC (Network Interface Card)
a television- like display device is called a
node
Softcopy
computers are called silico sepians
A device for detecting underwater objects is typically called a sonar device. Sonar uses sound waves to detect and locate objects underwater by measuring the time it takes for the sound waves to bounce off the object and return to the device.
It's called the rudder
SONAR True basically in principle but this doesn't fit, and I think that the answer is ASDIC or Anti-submarine Detection Investigation Committee, the former US name.

A device that listens for sources of underwater noise is called a hydrophone. Hydrophones are used in various applications, including marine research, underwater acoustics, and naval operations, to detect sounds such as marine life communication, geological activity, or human-made noises. They convert sound waves into electrical signals for analysis and monitoring.
The name of one such gas leak detection device is called Photoacoustic Multi-gas Monitor. This device and others can be found here: http://www.lumasenseinc.com/EN/products/gas-monitoring-instruments/gas-monitoring/innova-1314.html.
a divice that supplies air to underwater swimmers
The device that helps divers breathe underwater is called a scuba tank. Scuba stands for "Self-Contained Underwater Breathing Apparatus," which allows divers to carry their own supply of compressed air. This enables them to explore underwater environments safely and for extended periods. Additionally, divers often use a regulator to control the flow of air from the tank to their mouth.
SONAR is actually an abbreviation for SOund Navigation And Ranging. RADAR is correspondingly an abbreviation for RAdio Detection And Ranging. LIDAR is correspondingly an abbreviation for LIght Detection And Ranging.
DIODE
Asdic
The apnea detection device was developed by Dr. Benjamin Gilmartin, an anesthesiologist. He created the device to monitor apnea (temporary cessation of breathing) in patients undergoing anesthesia or in critical care settings.
