You may think you’ve seen a 3D multibeam fish finder in action, but many of those images begin disappearing as you approach 200 ft. Furuno’s DFF-3D takes 3D fish findings to new depths. We’re talking depths of over 980 ft, with side-scanning over 650 ft. 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 DFF-3D turns your NavNet TZtouch MFD into a multibeam fish finder that can see 120° port to starboard, allowing you to see the depth and direction fish schools are moving, while displaying the seabed condition in real-time.

Using the DFF-3D multibeam fish finder, PBG (personal bathymetric generator) allows you to create custom high-resolution shaded relief charts of the seafloor. Bottom images are drawn with shaded relief, depth contours, and variable colors, making it easy to identify hidden structures and ridges that hold fish in a simple, easy-to-interpret presentation. Multiple color palettes are available, including the ability to show contour lines only. The area each ping covers is approximately twice the depth at the time of recording, so at a depth of 100 m, a 200 m wide area is displayed and recorded to your TimeZero™ software, NavNet TZtouch3 or TZtouchXL or NavNet TZtouch2 TZT2BB.
 

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.

Cross section displays the real-time sea column echo in 120° 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 ft, depending on bottom, water, and installation conditions.

A single (directly under the boat) or triple direction (middle, left, and right) fish finder image is displayed simultaneously. The triple beam display helps to understand the depth of fish targets and the seabed condition in each direction, as well as the direction the target fish are moving. Each beam angle and beam width are selectable.

Side scan displays the shape of the 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 ft in a 120° swath port to starboard, a distance you've never seen before!
