Furuno NavNet TZtouch3 19" MFD 1kW Dual Channel CHIRP Sounder

The Furuno NavNet TZtouch3 19-inch MFD (MPN TZT19F) is Furuno's flagship 19-inch multifunction display, with a dual-channel 1kW TruEcho CHIRP fish finder built directly into the display itself. For sport-fishing operations, serious cruisers, and commercial-use helms that want the largest TZtouch3 display, the TZT19F packs MFD plus fish finder plus full network integration into a single glass-helm unit, eliminating a separate sounder black box and the network complexity it brings.

Built-in 1kW dual-channel TruEcho CHIRP fish finder. The dual-channel design means you can run two CHIRP frequency bands simultaneously, covering both shallow-water high-resolution structure and deep-water target detection without switching transducers or manually retuning. For sport-fishing operations that work multiple depths through the day, dual-channel is the difference between a flexible fish finder and one that's optimized for a single use case. TruEcho CHIRP signal processing delivers the target discrimination and detail that makes modern CHIRP sonar genuinely operational, not just a checkbox feature.

Quad-core processor for responsive operation. The quad-core processor handles chart panning, multi-panel switching, radar overlay, fish finder display, autopilot interface, and all the other MFD functions without the input delay that frustrates operators on older or lower-end displays. For helm operators who use the MFD as the primary instrument across long fishing days or offshore passages, the responsive performance is what makes the screen trustworthy under operational pressure.

19-inch IPS display. The 19-inch screen size makes multi-panel layouts genuinely usable, four-panel split (chart, radar, fish finder, instruments) at sizes you can actually read. The IPS panel technology delivers wide viewing angles that keep the screen readable from any helm position including off-axis viewing and with polarized sunglasses. For sport-fishing helms where the screen is referenced from the wheel, the tower, the cockpit, and the fish box, the wide angles are operationally meaningful.

Quad-screen display configuration. Run 1, 2, 3, or 4 different functions on the single 19-inch screen simultaneously. Common sport-fishing configurations: chart plus radar plus fish finder plus engine data. Common cruising configurations: chart plus autopilot plus wind plus AIS. Custom layouts per use case, and switching between layouts is one touch on the screen.

Built-in network capability. Connects via the Furuno NavNet network to additional MFDs (TZT9F/12F/16F/19F), the optional DI-FFAMP 2kW or 3kW Deep Impact CHIRP amplifier for serious deep-water fish finding (with 5kW or 10kW transducer compatibility, BT-5 required), the DRS NXT solid-state Doppler radars (100W or 200W with Target Analyzer, Fast Target Tracking, Bird Mode, Rain Mode), Furuno NAVpilot-300 or 711C autopilots for full autopilot control from the MFD, AIS, instruments, multi-beam sonar, and a wide range of additional sensors.

Backward compatible with TZtouch2 networks. For boats upgrading from a TZtouch2 helm, the TZT19F slots into existing TZtouch2 network topology, so you don't have to rebuild the entire helm electronics stack. Add a TZtouch3 alongside existing TZtouch2 displays and the network handles the mix.

Cloud route sync. Plan routes at home using TZ Navigator desktop software, the Cloud.MyTimezero.com web browser interface (US raster planning charts), or the TZ iBoat iOS app. Sync planned routes from the cloud to the TZT19F system before departure. For sport-fishing operations that plan multi-day trips with specific waypoints, the cloud sync eliminates manual data entry at the helm and reduces errors.

TZ First Mate App integration. Track your catch and location data through the TZ First Mate mobile app, with synchronization between tablet or smartphone and the TZtouch3 system. For sport-fishing operations that need catch logging for tournament records, fisheries reporting, or trip documentation, the mobile integration handles the data collection without manual logging.

CZone digital switching integration. Compatible with CZone distributed digital switching for whole-boat electrical control through the MFD. Lights, pumps, fans, audio, blinds, all controllable through the TZtouch3 interface when CZone modules are installed. For modern smart-yacht installs, the integration extends the MFD from navigation instrument to whole-boat control surface.

Weather data integration. Free weather data via NavCenter Weather, plus optional BBWX4 SiriusXM Weather Receiver for premium subscription weather services. For offshore operations where weather routing is operationally critical, the integrated weather data eliminates the need for a separate weather receiver instrument.

PIN Code Lock security. Four-digit password required at MFD startup, protecting the navigation data, waypoint library, and route history from unauthorized access. For charter operations, brokerages, or any boat where the MFD might be accessed by people who shouldn't have full data access, the PIN lock is genuinely useful.

Install considerations. The 19-inch flush mount requires precise dash cutout work for the glass-bridge aesthetic. Built-in dual-channel CHIRP sounder needs the right transducer for your hull and target species (Airmar B-series and similar 1kW transducers, sourced separately). NavNet network requires NavNet cabling and topology, plus power, NMEA 2000 backbone, and any radar/sonar/autopilot connections. Total install is a marine electronics installer day-plus for a clean glass-bridge integration. Not casual DIY because the cutout precision, transducer install, network integration, and TZtouch commissioning all benefit from professional setup.

Why pay this much. Three reasons. First, the 19-inch IPS display delivers multi-panel real estate that smaller TZtouch3 models can't, making the four-screen capability genuinely operational. Second, the built-in 1kW dual-channel CHIRP fish finder eliminates a separate sounder black box, simplifying the helm stack and reducing total cost when fish finder capability is the requirement. Third, the Furuno NavNet ecosystem (radar, autopilot, multi-beam sonar, CZone, weather, cloud sync, mobile apps) is mature and comprehensive, with commercial-grade engineering and proven service network. For owners building or refitting a serious helm on Furuno, the TZT19F is the MFD that earns its position.
