[. . . ] Withaclickontherequestedicon on the top bar, the information you wish to add to the echogram is presented in a dedicated frame. You can place the frame wherever you want, andyoucanresizeittoanyshape. It is even transparent, so you will not loose any information from the echogram behind it. New Zoom function Echo Position TheEchoPositionpane providesa3Dpresentation ofthesinglefishechoespresentlylocatedintheechosounder's beam.

Differentfishsizeandspecies havedifferenttargetstrengths. With thehelpfromthefisheryscientist weareabletocalculatefishsizesfor differentspecies. Withmorethan25 years split beam experience, Simrad has become the world leader using thistechnologyfordeterminingfish size. Multiple frequencies available Limitless capabilities Different frequencies and transducersareusedfordifferentfisheries. Mackerel, Tuna, Anchovies, Herring andotherschooledfisharebestmeasured using a high frequency system, typically120or200kHzdepending onthedepth. Cod, Pollock, Saithand otherbottomfishcanbemeasured using70or38kHzsystems, while18 kHzisusedfordeepwaterspecies. The Simrad ES70 echo sounder is more than a regular echo sounder. You can put together a system with as many transducers and frequenciesasyoulike, andbuildthe sounding system you always dreamed of:Lookingdownorsideways, fish volume, singlefishdetectioninshallow as well as deep water, bottom discrimination, history echogram, recording facility, unlimited personal settings, data output to plotter, etc. Long history, long experience Simrad has manufactured echo soundersformorethan60years.
