About
Furuno NavNet is Furuno USA's flagship integrated marine navigation platform, connecting a wide range of onboard electronics into a single cohesive network. The system is anchored by the NavNet TZtouchXL series of extra-large Multi-Function Displays (MFDs), featuring TZ MAPS with BathyVision, intuitive touchscreen interfaces, and compatibility with magnetron and Solid-State Doppler Radars. The ecosystem supports advanced fish-finding capabilities through the DFF3D Multibeam Sonar, which provides 120-degree port-to-starboard scanning at depths exceeding 980 feet, enabling real-time 3D visualization of fish schools and seabed structure. Radar options range from compact 2.2kW recreational units to commercial-grade 50kW systems, with features like Automatic Clutter Elimination (ACE) for cleaner target detection. Additional components include the GP170 GPS Navigator for large commercial vessels, the RD50 Remote Display supporting up to 10 networked screens, and the BBWX4 SiriusXM Satellite Weather Receiver. CAN bus networking enables seamless sensor integration across the vessel. NavNet is built for a broad audience: sport fishermen seeking cutting-edge sonar, recreational boaters wanting reliable chart plotting and autopilot, and commercial operators needing certified, dependable bridge electronics. Furuno backs the platform with decades of NMEA award-winning radar innovation and support for products dating back to 1970.

Frequently Asked Questions
What is Furuno NavNet?
Furuno NavNet is an integrated marine electronics network that connects Multi-Function Displays, radar, sonar, GPS chart plotters, autopilots, and other instruments into a unified navigation system for boats and ships.
What is the NavNet TZtouchXL?
The TZtouchXL is Furuno's latest generation of extra-large Multi-Function Displays, featuring TZ MAPS with BathyVision, intuitive touch interface, and compatibility with solid-state Doppler radars and multibeam sonar.
What depth can the DFF3D Multibeam Sonar reach?
The DFF3D Multibeam Sonar can reach depths of over 980 feet for fish finding and over 650 feet for side scanning, providing real-time 3D visualization across a 120-degree field of view.
Is NavNet suitable for commercial vessels?
Yes. Furuno offers commercial-grade products including the GP170 GPS Navigator (BAM-ready), FAR1518 Radar, and CSH8LMK2 Sonar specifically designed for ocean-going ships, ferries, and large commercial vessels.
How does CAN bus networking work in NavNet?
CAN bus allows multiple onboard sensors and instruments to communicate over a shared network, so data from GPS, radar, sonar, and other devices can be displayed and shared across all connected NavNet MFDs and displays.
