Black Box Bottom Discrimination FishFinder, MFG# BBDS1, 600/1000 Watts (transducer dependent), 50/200KHz, for use with NavNet 3D (not NavNet-1 or VX2). Requires specific trasducer for Bottom Discrimination feature (see Accessory List).

Depth Sounder Module for Furuno NavNet 3D Systems

The BBDS1 is a new network fish finder for NavNet 3D and NavNet TZtouch 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 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 consisiting of by displaying the possible bottom materials proportionally within the 4-color bar.

Appropriate transducer required. Only the transducers listed in the accessory list will work with Bottom Discrimination modes. Other transducers that will work in normal mode only are listed under Furuno transducers.
