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 transducer. Turn your NavNet TZtouch series 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.

Modes Overview

DFF-3D with four ground breaking modes bring a whole new dimension to your fishing.

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.

Triple/Single Beam Sounder

A single (directly under 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

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.

TZ Professional v3 with DFF-3D

When paired with TZ (TIMEZERO) Professional software and the optional PBG module, the DFF-3D can generate up to 50 depth points per second to quickly create a highly accurate Personal Bathymetric Generated (PBG) database. The following screenshots show how the PBG database is dynamically created with the DFF-3D, in comparison with conventional Fish Finder models.
