Furuno TZT2BB – NavNet TZtouch2 Black Box Chartplotter

The Furuno TZT2BB is a black-box chartplotter for a boat where the processor needs to sit away from the helm display. It can drive an external multi-touch monitor up to Full HD, making it useful for custom bridge layouts, commercial boats, and yachts with unusual console dimensions. The processor handles navigation and sounder functions, but the monitor, antenna, and transducer must be planned separately.

The built-in 50/200kHz sounder supports 600W or 1kW RMS, while optional TruEcho CHIRP, SideScan, and DFF3D modules expand the system. MapMedia, C-MAP, Navionics, and NOAA chart support gives the owner flexibility over chart data. Dual Ethernet, NMEA 2000, WiFi, USB, and HDMI provide the system connections. The processor is IP22, so it belongs in a protected bulkhead or electronics space rather than on an exposed deck.

Key Features

- Black-box chartplotter design – Lets the processor and external display be installed in different locations.
- External monitor support up to 1920 x 1080 – Works with compatible Full HD multi-touch displays.
- 50/200kHz built-in sonar with RezBoost – Provides conventional sonar through a suitable transducer.
- Optional TruEcho CHIRP, SideScan, and DFF3D – Allows the system to grow beyond the basic sounder.
- Dual Ethernet, NMEA 2000, WiFi, USB, and HDMI – Supports a custom Furuno network and video installation.

Who Is This For?

This Furuno black-box chartplotter suits custom glass bridges, commercial boats, and yachts where a separate monitor is preferred. It is not ideal for a simple installation or exposed mounting; the processor is IP22 and requires an external display, GPS antenna, and selected sonar hardware.

Compatibility

Confirmed features include external multi-touch monitors, MapMedia, C-MAP, Navionics, NOAA, NMEA 2000, dual Ethernet, WiFi, USB, HDMI, DFF3D, SideScan, and optional TruEcho CHIRP modules. The supplied information does not identify specific displays, radar, autopilot, or transducers. No named incompatible system was provided.

The TZT2BB is the flexible choice when a boat needs a custom Furuno bridge rather than a fixed all-in-one MFD. Its trade-off is the installation work: display, antenna, transducer, and optional sonar modules all need to be specified separately. Choose it for a planned vessel system, not a quick chartplotter replacement.
