Features

Internal Fish Finder

NavNet TZtouch2 is the first product from FURUNO to feature the brand new RezBoost™ technology.
Accurately spot individual fish and increase your catch.

Multi Beam Sonar
Innovative tool for exploring wide range of water column and seabedNEW

Scanning image of Multi Beam Sonar

New Multi Beam Sonar model DFF-3D gives you real-time 120° port-starboard view of the water column and seabed up to 200 m depth*. The DFF-3D allows you to explore fishing spots and find fish in deep water by far faster than conventional single beam sounders. Alternatively, the main beam penetrates right under the boat at a depth of approximately 300 m*. Installation is made easy, thanks to a compact transducer design. The built-in motion sensor gives you clear images under your boat even in rough water.

* Maximum depth dependent on installation, bottom type and water conditions.

For Multi Beam Sonar model DFF-3D, see https://www.furuno.com/special/en/fishfinder/dff-3d/ for details.

RezBoost™

Rezboost™ is a revolutionary new technology utilizing FURUNO's advanced digital signal processing to provide fantastic resolution without having to change your transducer.

Conventional Signal Processing
RezBoost™ Signal Processing

Every NavNet TZtouch2 display has a built-in Fish Finder that is dual-frequency (50/200kHz), and has a 600W/1kW power output. With TZtouch2, Furuno is introducing a new, proprietary Fish Finder technology, called RezBoost™. RezBoost™ is a revolutionary new feature that utilizes Furuno's exclusive digital signal processing protocol to produce fish targets and images that are up to 8 times sharper than a conventional Fish Finder*, without the need to change out your narrowband transducer^*1, or purchase an expensive broadband transducer.

* RezBoost™ performance may vary depending on depth, range and signal frequency used.
*1 To check if your transducer supports the "Enhanced Mode", see the list below on this page. In-hull mounted transducers are not compatible with RezBoost™ technology.

FURUNO Digital Filter (FDF™) Fish Finder

FURUNO Digital Filter (FDF™) Fish Finders feature advanced filtering capabilities and digital auto tuning, which eliminates noise. FURUNO FDF™ Fish Finders deliver the ability to spot individual fish with clarity, accuracy and detail. Whether in shallow or deep water, FURUNO FDF™ Fish Finders give you what you would expect from a Fish Finder at all times.

Up to 10 times sharper image than conventional FDF^*2

Find More Fish With TruEcho CHIRP™ Fish Finder

An advanced technology for both professional and enthusiast fishermen. Designed to operate across a wide range of frequencies utilizing a broadband transducer, the TruEcho CHIRP™ network Fish Finder delivers significant advantages in signal clarity and target definition. Due to the constant sweep of frequencies the TruEcho CHIRP™ network Fish Finder is capable of gathering more and higher quality data than a traditional single frequency Fish Finder. The clear presentation marks individual game fish and bait fish, even when tightly schooled together. TruEcho CHIRP technology delivers up to 10 times sharper image over conventional FDF^*2.

ACCU-FISH™ (Fish Size Analyzer)

The ACCU-FISH™ algorithm analyzes echo returns in order to compute individual fish size. The algorithm is capable of computing fish size ranging from 10 cm up to 199 cm long. Fish depth can also be displayed.

In some instances, fish size indicated on the NavNet TZtouch2 may differ from its actual size. Please carefully read the operator's manual prior to utilizing this feature.

Bottom Discrimination Display

Bottom discrimination provides detailed information about Knowing the make-up of the seabed, categorizing it into four different categories; “Rocks”, “Gravel”, “Sand” and “Mud”.
The make-up of the seabed can be tremendously helpful information when looking for fishing grounds, as well as for finding good anchoring spots.
