Furuno’s new DFF-3D sonar module, which employs a compact multibeam 165 kHz transducer (through-hull or transom-mount, with a built-in motion sensor), brings side-scanning and 3-D viewing to TZtouch and TZtouch2 multifunction displays. The DFF-3D unit offers four customizable display modes. Cross Section displays a real-time sea-column echo 120 degrees port and starboard; the 3D Sounder History mode shows 3-D images of the seafloor and fish icons; the Triple/Single Beam Sounder mode lets you see left, center and right images simultaneously; and Side Scan shows high-definition structure to either side of your vessel. The module costs $2,095 (without transducer).
