Key Features
- Instant TimeZero Chart Handling: The architecture of the Furuno NavNet 3D 8.4 facilitates instant chart redraw, allowing you to zoom and pan smoothly without the staggered steps found in inferior displays.
- Full-Time 3D Chart Rendering: You can choose a traditional 2D top-down view or utilize the scroll pad to pan and zoom the chart to any angle, creating an immersive perspective of both surface and underwater bathymetric data.
- Satellite Photo Fusion: Overlay high-resolution satellite photography directly onto your raster or vector charts.
- RotoKey & Cursor Pad Interface: The signature RotoKey rotary knob provides instant access to menus, while the point-and-click cursor pad allows for context-sensitive control of any data box on the screen.
- UHD Digital Radar Compatibility: Integrate with Ultra High Definition radar sensors for crystal-clear target presentation.
Applications
Used as a main or secondary helm display for chart, radar, and sonar information in coastal and offshore navigation. The screen format and network support make it practical for skippers who need one place to review key navigation layers while underway.
It also fits upgrade projects on existing Furuno networks where a dedicated display is needed for route planning, target awareness, or split-screen monitoring.
