Furuno This is a new network fish finder for NavNet 3D and NavNet TZtouch that features a bottom discrimination function, as well as the FDF (Furuno Digital Filter) capability of the DFF1. This module determines the bottom structure and separates them into the following categories: mud, sand, gravel, and rock. This is achieved by analyzing echo characteristics from the bottom components such as particle size and hardness. Connect the sounder to your NavNet 3D or NavNet TZtouch network and get ready for your NavNet system to provide you with valuable information to locate rich fishing grounds, boosting your catch. This unit is not designed to work with NavNet-1 or VX2 models.

There are two bottom discrimination display modes to select from, Standard Mode and Probability Mode. In Standard Mode, the most probable materials on the bottom (mud, sand, gravel or rock) are indicated in either graphic mode or a 4-color bar on the bottom of the display. Because bottom material can change frequently and can sometimes be difficult to identify, Probability Mode shows you what material the bottom has the greatest chance of consisting of by displaying the possible bottom materials proportionally within the 4-color bar. An appropriate transducer is required (sold separately).
