Contents of the Package


This network fish finder for the NavNet 3D and NavNet TZ touch offers an updated bottom discrimination function and the Furuno Digital Filter (FDF) capability of the DFF1.

By analyzing echo characteristics such as particle size and hardness, the BBDS1 determines the bottom structures and separates them by mud, sand, gravel and rock.

Use your touch network to connect the BBDS1 to your NavNew 3D or NavNet Tztouch network. Your NavNet system will help you locate rich fishing grounds, boosting your catch.

You can select from the Standard and Probability bottom discrimination display modes. Standard mode shows you the most likely materials bottom materials sand, mud, gravel or rock in either graphic mode or a four-color bar at the bottom of the display.
