Fu­runo’s DFF3D multibeam sonar is a net­work sen­sor that adds side-scan­ning func­tion­al­ity to its NavNet TZTouch and TZTouch2 mul­ti­func­tion dis­plays. Us­ing a 14-inch-long, multibeam trans­ducer, the DFF3D of­fers side-scan­ning range to 650 feet while down­scan­ning to depths bet­ter than 1,000 feet, ac­cord­ing to Fu­runo. The trans­ducer has a built-in mo­tion sen­sor that keeps the im­age sta­ble in rough con­di­tions. The com­pany’s pro­pri­etary sig­nal pro­cess­ing pro­duces images to help the user find and track fish. Four dis­play modes in­clude triple/sin­gle beam sounder, which al­lows tra­di­tional sonar views, or sep­a­rate the left, right and cen­ter images si­mul­ta­ne­ously. Mean­while, sides­can al­lows the user a high-def­i­ni­tion im­age of struc­ture on ei­ther side of the boat. The 3D sounder his­tory lets the user parse a de­tailed im­age of the seafloor to dis­cern tar­gets and op­ti­mal fish­ing struc­ture or an­chor­ing lo­ca­tions, while cross sec­tion dis­plays a real-time echo of the wa­ter col­umn out 120 de­grees to port and star­board. The var­i­ous modes al­low the user the flex­i­bil­ity to tai­lor the sonar view to the task at hand. With three-di­men­sional fish tar­gets dis­played in re­la­tion to the boat in real time, the DFF3D shares in­for­ma­tion that may help im­prove catch rates.
