Furuno DFF1 Sounder Specification

The Furuno DFF1 Sounder is a robust digital fish finder device designed to integrate seamlessly with the NavNet and NavNet vx2 series, offering advanced fish detection capabilities for both recreational and professional seafaring activities. The sounder operates on dual frequencies, 50 kHz and 200 kHz, allowing for versatile depth penetration and target separation. It boasts a transmission power of 600W or 1kW, which ensures optimal performance in various water conditions, providing clear and accurate fish echoes. The DFF1 employs Furuno's proprietary DSP (Digital Signal Processing) technology, which enhances target detection by minimizing noise and improving signal clarity, crucial for distinguishing fish from underwater structures. It supports multiple display modes, including single and dual-frequency displays, A-scope display, and zoom functions, facilitating precise monitoring and analysis of underwater environments. The compact unit is designed for easy installation and integration, requiring only a NavNet or NavNet vx2 display and a compatible transducer. Connectivity is achieved via an Ethernet interface, ensuring fast and reliable data transmission across the network. The DFF1 is engineered for durability, with a waterproof casing that withstands harsh marine conditions. Its user-friendly interface, combined with powerful processing capabilities, makes the Furuno DFF1 Sounder an ideal choice for users seeking an efficient and effective fish-finding solution.
