NOTE: AIRMAR NO LONGER MANUFACTURES THIS PRODUCT
Airmar has now made it possible for saltwater fishermen to “widen up” the high-frequency, 200 kHz performance for most of today’s popular fishfinders. The SB264 connects your existing, 1 kW, Airmar transducer and a newly-installed SS264W for wide and narrow-beam selection at your fingertips. The switchbox works with most of Airmar’s 1 kW transducers including the B260, M260, B258, and B256 found on boats from center consoles to large, sportfishing vessels.
Installers can leave any of these models in place and mount an additional SS264W Tilted Element™ transducer, then wire both into the SB264. The waterproof panel-mount switch is easily installed and takes minimal space. This lets the operator toggle between 200 kHz wide (25°) or narrow-beam (6°) fish finding, together with the 50 kHz low-frequency operation.
Traditionally at 200 kHz, most transducers have a narrowly focused beam in which fish swimming near the boat can go un-marked because they are outside of the transducer beam. At 50 kHz, the beam is wider, thus marking more fish, but resolution and detail are not as crisp. Tightly-spaced fish tend to appear on the fishfinder screen as one large target or “blob". The SS264W, 200 kHz, transducer provides the coverage and resolution needed so that fishermen do not miss any fish or bait lurking close to the boat. Additionally with the, tightly-spaced fish appear on the fishfinder screen more as individual targets and as arches.
Wide-beam, 200 kHz operation is great when trolling or searching for fish in the mid to upper portion of the water column. This makes it ideal for tuna and marlin fishing. Switching to a more traditional, narrow-beam, 200 kHz operation works best when bottom fishing for cod or grouper in waters up to 122 m (400'), providing optimal bottom detail and separation between the bottom and tightly-spaced fish targets. A narrow and wide beam, 200 kHz combination on the boat caters to the versatile fisherman who may be bottom fishing with a narrow beam in the morning and tuna or marlin fishing with the SS264W, 200 kHz by afternoon.
