Echo Sounder
An Echo Sounder is a marine instrument used to measure the depth of water beneath a vessel by transmitting sound pulses downward and recording the time it takes for the echo to return from the seabed. This time measurement is converted into depth using the speed of sound in water. Echo sounders are essential for safe navigation, especially in shallow or unfamiliar waters, as they help prevent grounding and allow accurate charting of underwater terrain. Modern echo sounders often display depth readings digitally and can provide additional information such as bottom contour and sediment type. They are widely used in commercial shipping, fishing, and hydrographic surveying to ensure precise depth awareness and improve operational safety.
Furuno FE-800
The FE800 is a result of Furuno's many decades of experience developing echo sounders, sonars, and underwater application equipment and systems. This echo sounder is a breakthrough over the conventional paper 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 the SOLAS Convention ships by the new IMO standards. The basic system consists of a display unit and distribution box. The 8.4" high-brightness color LCD display offers an easy-to-read depth sounding in various modes, permitting optimum representation with respect to the environment.
