The BBDS1 is a network fish finder for NavNet 3D, NavNet TZtouch and NavNet TZtouch2 that features an all new bottom discrimination function, as well as the FDF (Furuno Digital Filter) capability of the DFF1. The BBDS1 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 BBDS1 to your NavNet network and get ready for your system to provide you with valuable information to locate rich fishing grounds, boosting your catch. 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.
