Furuno DFF3 Black Box Sounder
$1,439.00
Furuno DFF3 Black Box Sounder is a network sounder for NavNet systems with selectable 1 kW to 3 kW output, adjustable dual frequencies from 28 to 200 kHz, and deep-water capability.
Overview Furuno DFF3 Black Box Sounder
Furuno DFF3 Black Box Sounder is a high-power network sounder module for NavNet, NavNet vx2, and NavNet 3D systems. It is designed for deep-water fishing operations that need selectable 1 kW to 3 kW output and flexible dual-frequency control rather than fixed-frequency operation.
Furuno Free Synthesizer and Furuno Digital Filter technologies allow the installer to tailor the sounder around the transducer and target fishery. Ethernet networking also makes it practical for multi-display bridges where sonar data needs to be shared across the helm.
Key Features
- Selectable 1 kW to 3 kW output: Gives the system enough headroom for serious deep-water sounder use.
- Adjustable dual frequencies: The source data lists user-adjustable operation between 28 kHz and 200 kHz.
- FFS and FDF processing: Supports more flexible setup and cleaner target presentation than a basic fixed-frequency module.
- Deep-water range: Source information lists operation up to 3,000 meters / 10,000 feet.
- Networked bridge use: Ethernet connectivity allows sonar data to be shared around compatible NavNet systems.
Applications
Best suited to commercial fishing, deep-water sportfishing, and larger vessels that want a networked black-box sounder with more flexible frequency control and stronger depth reach.
