Revolutionizes finding fish with new bottom discrimination fish finding feature
The Furuno BBDS1 Bottom Discrimination Sounder is a new network fishfinder 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 analysing 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.
Choose between 2 Bottom Discrimination Display Modes
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-colour 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-colour bar.

Notes:
- The result shown by this function may sometimes be
different from the actual bottom components.
- For best performance, do not use in-hull mounted
transducers with the BBDS1.
- The BBDS1 may show an incorrect ground discrimination
result, especially when there is a big fish school right under the
boat. This is because enough echoes may not be received from the
bottom.
- Materials such as shell, coral, or a sunken ship are
indicated as the most similar material from the four bottom
categories: mud, sand, gravel, or rock, according to reflected
echoes.
- Auto mode is automatically activated when the bottom
discrimination function is turned on. (Manual mode is not
selectable.)
- The BBDS1 is not compatible with NavNet 1 or NavNet
vx2.
- Use appropriate Furuno Transducer recommended for best
results
