Furuno DFF1-UHD CHIRP Sounder Module is a 1 kW black-box TruEcho CHIRP sounder for compatible NavNet systems, with broadband frequency sweeping, Accu-Fish, and bottom discrimination.
Overview Furuno DFF1-UHD CHIRP Sounder Module
Furuno DFF1-UHD CHIRP Sounder Module is a 1 kW black-box sonar processor designed for compatible NavNet TZtouch, TZtouch2, TZtouch3, and NavNet 3D systems. It uses TruEcho CHIRP processing to sweep across many frequencies instead of relying on one fixed transmission point.
The result is a network sounder aimed at better fish separation, clearer bottom reading, and improved seabed interpretation on a compatible display. Its remote-mount format also suits bridges where sonar performance is needed without adding another front-panel unit.
Key Features
- 1 kW TruEcho CHIRP sonar: Uses broadband frequency sweeping to improve detail compared with a narrow single-frequency approach.
- 90-frequency sweep range: The source data lists 50 kHz ± 20 kHz and 200 kHz ± 25 kHz coverage.
- Fish and bottom analysis tools: Bottom discrimination and Accu-Fish functions help turn raw sonar returns into more useful information.
- Ethernet network integration: Designed to feed compatible NavNet systems from a protected mounting location.
- Longer-range CHIRP use: Source data lists maximum range up to 1,200 meters depending on the transducer.
Applications
A strong choice for offshore and coastal boats using compatible Furuno displays that want CHIRP target separation, bottom reading, and seabed analysis from a dedicated black-box module.
