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
  • Sidebar detection range is over 650' (200 m) in a 120 deg. swath port and starboard direction
  • Deep water, main beam penetration directly under the boat is over 1,000' (350 m), depending on water conditions
  • Rich set of menus in each display mode
  • The built-in motion sensor (standard supply) stabilizes the display to give clear and stable images even under rough sea conditions
  • Thru-hull or Transom mount transducers available
  • Customize the display according to your needs
    • Depending on the situation and preference, a combination of screen modes can be displayed
