Detailed explanation-1: -Answer: The correct answer is (4) Fathometer. A Fathometer is a gadget that is often used for measuring the ocean and sea depth. It is sometimes called 312 Fathometer. It is generally attached beneath a ship or boat and produces echoes and sound waves into the water for measuring the ocean depth.
Detailed explanation-2: -Multibeam echosounders (MBEs), a type of sonar that sends out rapid sound waves in a fanlike formation to scan the bottom of the ocean floor, are used by the National Oceanic and Atmospheric Association (NOAA) to measure the depth of the ocean.
Detailed explanation-3: -A fathometer is one such device that is used to determine ocean depths.
Detailed explanation-4: -A tachometer (revolution-counter, tach, rev-counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.
