Sügavusmõõtur
A sügavusmõõtur, also known as a depth sounder or fathometer, is an instrument used to measure the depth of water. These devices typically operate by emitting sound pulses into the water and measuring the time it takes for the echo to return after reflecting off the seabed or a submerged object. The time taken for the sound to travel down and back is directly proportional to the depth.
Modern sügavusmõõturid often employ sonar technology, utilizing transducers to both transmit and receive the sound waves.
These instruments are essential tools for a wide range of marine activities. Navigators use them to avoid
