  \: d3 o, |( i& M! yThe history of echo sounders dates back to the early 20th century when scientists and explorers recognized the need for accurate measurements of ocean depths. The first primitive versions of echo sounders relied on basic principles of acoustics, sending out sound waves and measuring the time taken for the waves to bounce back from the seafloor. However, these early devices were limited in their capabilities and often provided unreliable data.
