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 new 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.
