Humminbird's DualBeam sonar combines the advantages of narrow- and wide-beam transducers into one system with wide coverage and better bottom definition. Its precision 20° at -10db 200kHz down-looking center beam looks for fish and structure directly below the boat, while the broad 60° at -10db 83kHz wide beam looks for fish outside the narrow beam around the boat. The Fish Identification feature gives more information on location than a traditional single beam: Fish in the narrow beam are displayed as solid fish symbols; fish in the wide beam are shown as hollow fish symbols. All-new housing design with SD card slot.
I bought this unit this past spring with high hopes because of what they said this unit could do. I put the lakemaster card in it and set out to find the fish. I started finding fish right away while trolling and came across some real good areas. I found several good areas on several lakes that I marked with the GPS and was able to come right back to them later. When the ice moved in I was able to use these way points to find the spots again and keep catching fish. I've just returned from an ice fishing trip and was wondering why anyone would ever buy anything else. This baby does it all and does it well. Hummiingbird may have just made most everything else they make obsolete cause this is all you need year round.
