DFF-3D Network Multi-Beam Sonar

The DFF-3D is an innovative tool for efficient fish location and seabed profile surveying, utilizing new multi-beam technology. Highly detailed images are derived from the combination of an advanced signal processing system and an amazingly compact multi-beam transduc


Visibly see the landscape and fish schools at great depths in amazing detail

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.

  • Sidebar detection range is up to 200 m (over 650 feet)* in a 120-degree swath port and starboard direction.

  • Deep water, main beam penetration directly under the boat is approx. 300 m (over 980 feet)*. *Depending on bottom, water and installation conditions.

The compact and fully featured transducer

  • The compact transducer allows easy installation.

  • The built-in motion sensor (standard supply) stabilizes the display to give clear and stable images even under rough sea conditions.

Customize the display according to your needs

  • Depending on the situation and preference, a combination of screen modes can be displayed.

Cross section

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.

3D Sounder History

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.

Side Scan

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.
