Furuno DFF3D Multi-Beam Sonar f/NavNet TZtouch & TZtouch2

Furuno DFF3D | Multi-Beam Strategic Innovation

Furuno DFF3D addresses the demand for wide-swath situational awareness by utilizing a 165 kHz multi-beam sonar engine that provides a 120-degree port-to-starboard view. By integrating specialized signal processing, the system mitigates the narrow-beam constraints of traditional sonar, allowing navigators to see fish and structure up to 650 feet on either side in real-time. This tactical advantage ensures that commercial and offshore navigators can scout massive areas of the water column in a single pass, preventing the loss of pelagic pods that would be missed by conventional vertical sonar.

From a system integration standpoint, the DFF3D requires an Ethernet connection to a NavNet TZtouch, TZtouch2, or TZtouch3 display to render its unique 3D Sounder History and Cross-Section views. In demanding offshore conditions, it is vital to utilize the built-in motion sensor to stabilize the 120-degree sweep against vessel pitch and roll. System performance depends on clean data flow; don’t share the sounder’s network loop with high-latency devices, as the high-bandwidth 3D rendering requires optimized data throughput to maintain its fluid 3D structural visualization.
