Furuno DFF3 Network Sounder: High-Performance Marine Echo Sounder
The Furuno DFF3 Network Sounder is a state-of-the-art black-box echo sounder designed for professional marine applications. It offers high-resolution sonar imaging and is ideal for fishing vessels, research boats, and navigation operations. By integrating seamlessly with Furuno’s NavNet series displays, the DFF3 provides real-time, detailed underwater images, making it easier to detect fish, map the seabed, and avoid obstacles.
Key Features:
Dual-Frequency Operation: The DFF3 utilizes advanced Free Synthesizer (FFS) technology, allowing users to select two frequencies between 28 kHz to 200 kHz. This flexibility allows for optimal imaging in varying water depths and conditions.
Variable Output Power: With selectable output powers of 1, 2, or 3 kW, the DFF3 can adapt to different operational needs, making it suitable for a wide range of vessels.
Advanced Signal Processing: Equipped with Furuno’s Digital Filter (FDF) technology, the DFF3 enhances target detection, providing clearer sonar images with improved bottom discrimination.
Heaving Compensation: When connected to a Furuno Satellite Compass, the DFF3 compensates for vessel heaving, ensuring stable sonar readings in rough seas.
ACCU-FISH™ Target Identification: With compatible transducers, the DFF3 can provide individual fish target identification, including size and depth, helping to improve fishing operations.
Broad Compatibility: The DFF3 integrates seamlessly with Furuno’s NavNet, NavNet vx2, NavNet 3D, and NavNet TZtouch series displays, making it easy to incorporate into existing onboard systems.
