NAVIGATIONAL ECHO SOUNDER
echo sounders, sonars, and underwater application equipment and systems. This echo sounder is a breakthrough over the conventional paper eating sounders; there are no consumable items. The purpose of the echo sounder is to provide safe navigation by detecting the clearance below the ship (particularly in shallow waters) as required on

Modern echo sounders use split-beam transducers and hydroacoustic systems to estimate fish size and track fish movement in 3D. The document discusses echo sounders and factors that affect the speed of sound in water. [1]
Echo sounder | Nautical Science Grade 12
Except on digital displays, various range scales can be displayed, ie 0 to 10 metres, 0 to 20 metres, etc. Echo sounders usually operate in the 10 to 55 Khz frequency range. The human ear can only hear sound in the 8 Hz to 18 Khz range. The echo sounder frequency range is therefore referred to as ultra sonic.

What is an echo sounder Device used to measure depth of water short pulse sound energy transmitted vertically down Time taken for it to echo back is used to determine depth Time taken (t ) = (2 x d) / v or d =(v x t)/2 Factors affecting echo sounder : Temp of water, pressure,salinity
Echo Sounders Flashcards
Explain the basic operation of an Echo Sounder. Click the card to flip 👆. In a vertical Echo Sounder, a pulse of sound is transmitted towards the sea bed from a transducer on the underwater hull of a ship. On reaching the sea-bed, part of the sound is reflected back. Given the speed of sound in water (usually 1500m/s) and the time interval ...

Doppler Log
When the signal of echo sounder is bounced off the seabed, the speed indicated will be in relation to the fixed seabed and will, therefore, be speed over the ground. Athwartship Speed The unique feature of some of the Doppler log is to provide athwartship speed over ground, which was never possible by any other logs.
