NavNet 3D Digital Sensors
Reliability of NavNet 3D lies in its excellent sensor performance, which is the result of the
application of advanced Digital Signal Processing to both NavNet 3D radar and fish finders.
These NavNet 3D digital sensors greatly boost your target detection and presentation
capabilities.
FURUNO has taken its NMEA award-winning radar technology to the next
level with Ultra High Definition Digital Radar. UHD
TM
offers crystal clear target
presentation with automatic real-time digital signal processing. Antenna
rotation speed (24/36/48 rpm) is automatically shifted appropriate to the
pulse length you operate with. Commercial-grade radar performance is now
available in the NavNet 3D ultimate leisure navigation suite.

NavNet 3D Real-time Digital Auto Gain/Sea Clutter Controls
NavNet 3D employs revolutionary real-time digital auto
Gain/Sea controls to deliver crystal clear radar presentation.
With this new technical application, NavNet 3D computes
and applies an adaptive omni-directional anti-clutter lter
with variable intensity depending on bearing.

Real-time Dual Range Radar
NavNet 3D’s simultaneous scanning technology drives
our powerful dual-range radar, providing unsurpassed
target detection. With each sweep of antenna, dual
progressive scan transmissions are sent, received and
processed to display two separate radar ranges on your
NavNet 3D display all at the same time. Each radar
presentation acts autonomously, allowing for
manipulation of individual gain and clutter controls.
FURUNO Digital Filter (FDF
TM
) Fish Finder
FURUNO’s DFF1 and DFF3 and new BBDS1 (available Late 2010) feature the
FURUNO Digital Filter (FDF
TM
) technology. These new digital Network Sounders can
turn any NavNet display into a powerful, dual frequency digital fish finder.
The main difference between digital and conventional fish finders
lies in the filtering capabilities and auto adjustments. Our award
winning FDF
TM
technology helps to optimally adjust gain, STC
(Clutter) and output power as well as suppress surface clutter. It also
makes the picture clearer and easier to decipher. However, even the
best digital filter won’t help unless you start with a solid basis, such
as FURUNO’s renowned fish finder technology. This is why FURUNO
has been the best friend of fishermen for generations.
Standard mode:
Only the most prominent bottom category
of the spot will be displayed.
Probability mode:
The proportion of the bottom sediment of
the spot is displayed in graph.
Bottom Discrimination Display (with BBDS1 only)*
NavNet 3D can show the bottom discrimination information from the depth sounder echogram.
Utilizing the new Network Fish Finder BBDS1 (available Late 2010). Bottom discrimination can be
displayed in four categories. "Rock", "Gravel", "Sand" and "Mud", in either easy to read graphics of
color display modes. The bottom discrimination function provides you with valuable information to
help you locate rich shing grounds to boost the days catch. There are two bottom discrimination
diaplay modes selectable:
* Bottom discrimination display mode can be used in the following conditions:
Water depth: 5 m and deeper**
** Please note, the water depth figures above are a guide only and operational performance may vary depending
on transducer installation technique and the acoustic environment around the vessel.
