What is Fathometre?

A fathometer is an instrument used to measure the depth of water, typically in oceans, seas, or large bodies of water. It operates by sending sound waves from a transmitter to the seabed and measuring the time it takes for the echoes to return. This data is then used to calculate the depth, often expressed in fathoms, which is a unit equivalent to six feet. Fathometers are commonly used in navigation, fishing, and marine research.
