Furuno DFF3D Multi-Beam Sonar for NavNet TZtouch, TZtouch2 & TZtouch3

Furuno DFF3D

You may think you’ve seen 3D Multi-Beam Sonar in action, but many of those images begin disappearing as you approach 200 feet. The Furuno DFF3D takes 3D fishfinding to new depths. We’re talking depths of over 980 feet, with Side Scanning over 650 feet. See fish and bottom structure as you’ve never seen them before, at depths previously unfathomable. Now you can visibly see fish schools and the underwater landscape at great depths in amazing detail. The Furuno DFF3D turns your NavNet TZtouch, TZtouch2 or TZtouch3 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.

Instantly understand fish distribution at a glance

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 the water column condition, with a detection range of over 650 feet, depending on bottom, water and installation conditions.

Better understand the depth of fish targets

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 a fishing hot spot and assessing the seabed condition

See the seafloor structure like never before

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 the sea floor structure. The sidebar detection range is over 650 feet in a 120-degree swath port to starboard, a distance you've never seen before!

"Furuno's DFF3D is a total game-changer for coastal anglers looking for a competitive edge. If you have the discretionary funds to upgrade to a commercial-grade, wide-angle 3D sonar that gives you a look at the ocean and fish schools under your boat like never before, that future is now."

-Capt. John Raguso, The Fisherman Magazine
