An echo sounder is a type of sonar used to measure the depth of water by transmitting sound pulses. Along with the speed of sound in water at the time, the time interval between emission and return of a pulse is used to determine the depth of water.
Omega provides one of the markets most sold model. With graphics and relevant navigational details continuously shown on the LCD, this echo sounder provides history memory that stores depth, time and other available navigation data for the preceding 24 hours. It has three transducer connections with resonant frequencies of 38, 50 and 200kHz. By choosing the corresponding transducer in the menu, each one can be shown on the display at a time. External connectors are provided for printer, VGA and NMEA in/output.
