Buscando por ahi me encontré esto: (en Ebay precios variados hasta 50 eu)


This amazing product is especially designed for amateur and professional fishermen alike, to find out the location of fish and depth of water. The unit can be used in ocean, river or lake and is fantastic for detecting schools of fish in any particular area. Using amazing and innovative technology, this portable fish finder is the ideal tool to bring the fish to you!

Sonar technology is based on sound waves. The system uses sonar to locate and define structure, bottom contour and composition, as well depth directly below the transducer. The transducer sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off an object; it then uses the reflected signal to interpret location, size, and composition of an object.

Hola gracias por tu comentario. ¿podrías decirnos que tal lectura hace en movimiento?

[Amelius]

no lo he probado con el barco en movimiento
si, desde un muelle y desde una zodiac pero parados
no lo e puesto como instalacion fija....
ya que el transductor flota con la boya amarilla
tiene un monton de cable y no me a dado por desmontarlo
y acortarlo
(por el riesgo de pillarlo con la helice)
repito mis pruebas fueron siempre en parado
