Furuno DFF1UHD+ TruEcho CHIRP Fishfinder w/Side-Scan Black Box Sounder

The Furuno DFF1-UHD+ is a black-box TruEcho CHIRP fishfinder with CHIRP Side-Scan for NavNet TZtouch systems. It provides 1kW output and three frequency bands from low through high, making it a useful sounder module for offshore fishing boats and cruisers that already use a Furuno network. It is not a display or transducer package, so both the screen and sensor are separate.

The low, medium, and high ranges cover 25-210kHz, allowing the transducer choice to match shallow structure work or deeper fishing. Side-Scan reaches up to 750 feet on each side, giving 1500 feet of total listed coverage when the transducer and conditions support it. The 10/100 Ethernet port connects to NavNet TZtouch 2, TZtouch 3, or TZtouch XL systems. Plan the DFF1-UHD+ together with the display, transducer, network, and power supply.

Who Is This For?

This Furuno CHIRP Side-Scan sounder module suits offshore fishing boats, charter vessels, and NavNet TZtouch owners who want more sonar capability. It is not ideal for buyers without a compatible NavNet display or transducer, because the DFF1-UHD+ is a black-box module rather than a complete fishfinder.

Warranty & Support

Furuno provides a 2-year standard warranty. The supplied specifications do not state warranty exclusions or service procedures.

The DFF1-UHD+ is a strong choice when a NavNet TZtouch system needs CHIRP and Side-Scan without replacing the main display. Its trade-off is the installation scope: the black box, compatible transducer, Ethernet connection, and display all need to be planned together. Choose it for a Furuno networked fishfinder system, not a standalone sounder.
