Imagine scanning the underwater world in stunning detail, spotting fish schools darting left or right, and mapping the seabed like never before. The Furuno DFF3D transforms your NavNet TZtouch or TZtouch2 multifunction display into a powerful multi-beam sonar system. With its wide 120-degree port-to-starboard coverage, you get real-time insights into fish movements and bottom structures, making it a game-changer for serious anglers chasing deep-water trophies.
Unlike traditional single-beam sounders that only peek straight down, this sonar sweeps a broad area, revealing baitfish distributions and hidden hotspots faster. Whether you're trolling offshore or bottom fishing, the DFF3D's main beam dives deep—often beyond 1,000 feet—while side beams cover over 650 feet sideways, all stabilized by a built-in motion sensor for crystal-clear images even in choppy waters.
The DFF3D offers versatile display options tailored to how you fish, letting you switch seamlessly between modes on your MFD.
Get a live, vertical slice of the water column across 120 degrees. This mode shines for tracking baitfish layers and current influences, helping you position your boat perfectly over active zones.
Relive your path with a rotatable 3D seabed map, complete with fish school markers. Ideal for pinpointing wrecks, drop-offs, or ledges that hold big game, it turns past scans into future success.
Monitor straight down, left, and right simultaneously. Adjustable beam angles and widths let you customize for precise targeting, revealing fish depth and movement direction in one glance.
High-definition portraits of underwater structures emerge port and starboard. Perfect for scouting reefs or searching vast flats without missing a thing.
This isn't just sonar—it's your underwater scout. Traditional fish finders leave you guessing about fish direction and seabed details. The DFF3D eliminates that, letting you:
Compact design means straightforward integration into your existing NavNet setup, without major hull modifications.

It uses multi-beam technology for 120-degree side coverage, showing fish direction and seabed in 3D, far beyond single-beam limits.
Side beams reach over 650 feet (200m), with the main beam penetrating beyond 1,000 feet (350m) under the boat, depending on water clarity and bottom type.
Yes, the built-in motion sensor stabilizes images, providing clear views despite boat motion.
It's designed for NavNet TZtouch and TZtouch2 multifunction displays via Ethernet connection.
Absolutely—adjust angles and widths in triple-beam mode, and combine display modes to suit your fishing style.
No, compact transducers offer thru-hull or transom options, and it connects easily to your existing NavNet network.
It runs on 12-24 VDC, drawing about 1.4 Amps max, fitting standard marine electrical systems.
DFF3D Multi-Beam Sonar for NavNet TZtouch & TZtouch2
Turn your NavNet TZtouch or TZtouch2 MFD into a multi-beam sonar that can see 120-degrees port to starboard, allowing you to see the depth and direction fish schools are moving, while displaying the seabed condition in real time. The DFF3D gives you real-time 120 port-starboard view of the water column and seabed in over 650 feet. The DFF3D allows you to explore fishing spots and find fish in deep water far faster than conventional single beam sounders. The main beam penetrates right under the boat at a depth of over 1,000 feet, depending on water conditions. Installation is made easy thanks to a compact transducer design. The built-in motion sensor in the transducer stabilizes the display to give clear and stable images, even under rough sea conditions.
Cross-Section displays the real-time sea column echo in 120 degrees port and starboard. This mode aids in instantly understanding the distribution of bait fish and water column conditions.
The 3D Sounder History provides an intuitive and easy-to-understand 3D image of the seafloor, along with fish school icons. This mode is useful in a variety of situations, such as selecting fishing hotspots and assessing the seabed condition.
A single (directly under the boat) or triple-direction (middle, left and right) fish finder image can be displayed. The triple beam display helps to understand the depth of fish targets and the seabed condition in each direction, as well as the direction target fish are moving. Each beam angle and beam width are selectable.
Side scan clearly displays the shape of structure as a high definition image in port and starboard direction. It is suitable for searching the seabed and understanding sea floor structure.
