1. Overview
The Fish Finder consists of a high power transmitter, sensitive receiver and a
transducer. The Fish Finder sends an electrical pulse to the transducer which
contains an element that converts the pulse into acoustic (sound) wave which is
sent through the water. As this wave travels from the transducer to the bottom, it
may strike fish, structures, thermoclines (temperature changes in the water).
When the wave strikes an object(s) a certain amount of the wave is reflected back
to the transducer depending on the composition and shape of the object. When
the reflected wave is returned to the transducer it is converted into a voltage and
is amplified by the receiver, processed and sent to the display . The speed of sound
in water is roughly 4800 ft./sec, so the time lapse between the transmitted signal
and the received echo can be measured and the distance to the object determined.

The following is a short description of terms listed in the previous Fig. 2.1:
Warning Message
Flashing label "Simulation" when the echo sounder is in Simulation mode.
Echogram window
Graphic presentation of sonar soundings recorded as a continuous profile
scrolling across the screen from right to left. Such recordings represent the
image of the water beneath your boat, items appear as they pass under your
transducer; the items on the right side of the screen are closer to you than
those on the left. The correct interpretation of the Echogram allows retrieving
useful information about what is under the boat. See the following Par. 2.1.1
for more information.
Color Bar
Colored scale located on the left side of the screen that shows the colors used
in the Echogram to represent the echoes strength. The color on the top of the
bar represents the maximum sonar strength, while the color on the bottom of
the bar represents the minimum sonar strength.
Page 10
12 User Manual
Digital Depth
Readout of the current bottom depth.
Water Temperature
Readout of the current water temperature returned by the TEMP 1 sensor
included into specific transducers.
Alarm Bar
Bar located on the right side of the Depth Ruler, showing the shallow water
and deep water alarm values. The alarm is triggered when depth is outside
the range.
Depth Ruler
Vertical graduated bar located along the right side of the screen. It is a scale
which reflects the depth of the area being displayed.
Variable Depth Marker (VDM)
Horizontal line on to the Echogram window with a depth label. The up/down
cursor keys can move it up and down. The label displays the depth of the
cursor position. It can be moved to any location pinpointing the depth of a
target.
Zoom Bar
Bar located on the left side of the Depth Ruler, showing the portion of the
Echogram currently represented in the zoomed window (on the left part of
the screen). It is turned On selecting the Echo Sounder Split page.
A-Scope
A real time representation of fish and bottom features passing through the
beam of the transducer. It is drawn as horizontal lines whose length and hue
is proportional to the sonar strength returned. When the default palette is
selected, the strongest sonar returns will be shown as the color displayed of
the top of Color Bar while the weakest as the bottom color.
Operating Frequency
Readout of the selected operating frequency.

User Manual
Fishes
Fishes are represented as arcs because of the cone angle of the transducer.
In fact as the boat passes over the fish the leading edge of the cone strikes
the fish, causing a display pixel to be turned on. As the boat passes over the
fish, the distance to the fish decreases turning each pixel on at a shallower
depth on the display. When the boat is directly over the fish, the first half of
the arch is formed and since the fish is closer to the boat, the signal is stronger
and the arch is thicker. As the boat moves away from the fish, the distance
increases and the pixels appear at progressively deeper depths forming the
remaining half of the arch.
Thermoclines
Are the zones where two layers of different water temperatures meet. The
greater the temperature differential, the thicker the thermocline is shown on
the screen. Thermoclines are represented as horizontal stripes of noise. They
are very important for fishing since often many species of game fish like to
suspend in, just above, or just below the thermoclines.
White Line
The White Line shows the difference between hard, soft bottoms and even
distinguishes between fishes and structures located near the bottom. In this
way it is easier to tell the difference between a hard and soft bottom and even
to distinguish fishes and structures located nearby the bottom. For example,
a soft, muddy or weedy bottom returns a weaker echo that is shown with a
narrow white line while a hard bottom returns a strong echo that causes a
wide white bottom line.
Surface Clutter
Appears like noise at the top of the screen extending many feet below the
surface. It’s caused by many things, including air bubbles, bait fish, plankton
and algae.
Structures
Generally, the term “structure” is used to identify objects like wrecks and
weeds rising from the bottom.
Bottom Echo Profile
Bottom profile recorded by the Fish Finder. When the echo sounder is set in
auto-range mode it is automatically kept in the lower half of the screen.
Other Elements
Large anchoring cables are returned by the echo sounder as very long and narrow
arcs on the screen.

We recommended the installation of a switch and a (5A) fuse in the positive DC
supply to the BB 50/200. The BB 50/200 is active sending the digital depth through
the NMEA interface even when the power (chart plotter) is turned off, thus the
need for a switch.

The transducer is a device that transmits and receives sound waves into the
water. The active component inside the transducer is commonly referred to as an
element but actually is a piezoelectric ceramic material.

6. Frequently Asked Questions
6.1 How can I disconnect the cables from the BB 50/200 in
case I need to do so for the installation?
♦ Open the BB 50/200 box unscrewing the four screws (see the following
figure).
Fig. 6.1 - The BB 50/200
♦ Once the screws are removed, pull out the panel and the Printed Circuit
Board (PCB). Unscrew the cables from the PCB.
♦ Wire the cables as needed.
♦ Reconnect the cables to the PCB (see the Fig. 4.5 for reference).
♦ Push the panel towards the case (be sure to have well positioned the
rubber gasket). Close the BB 50/200 box screwing the four screws.
6.2 How can I set optimal operating parameters.
Optimal operating parameters can be set accordingly with the intended use of the
Fish Finder, anyway to quickly get optimal operational parameters for fishing it is
possible to select the FISH preset from the Fish Finder Setup menu, while for
cruising it is possible to select the CRUISE preset.
6.3 What are preset modes?
Preset modes are pre-defined settings of the Fish Finder operating parameters.
You can use them to quickly set the Fish Finder in the most commonly used
operating modes. These are:
♦ CRUISE: sets the Fish Finder in full auto mode with the sensitivity set-
tings (GAIN OFFSET, NOISE level and STC) optimized for displaying at
best the bottom.
♦ FISH: sets the Fish Finder in full auto mode with the sensitivity setting
optimized for target searching.
6.4 How can I restore the Fish Finder default operating
parameters?
Simply select the CRUISE or the FISH preset. This will restore optimal operating
parameters for either cruising or fishing.
Page 36
38 User Manual
6.5 Can I always leave the Fish Finder in Full Auto/(Auto Gain
and Auto Range) mode?
Yes, but note that the full auto mode suits 90% of the cases, however in extreme
situations the auto modes may fail and thus it is necessary to switch to the Manual
mode.
6.6 What are extreme situations in which Auto modes may
fail?
When the bottom is very deep, at high boat speed, when the bottom is very
shallow (< 5Ft), when the water is full of materials in suspension, with bad sea
conditions.
6.7 What should I do if the Auto modes fail?
Failure of auto modes can happen for various reasons. Hereafter you can find a
range of possibilities.
6.7.1 Auto Range fails in very shallow waters displaying a digital depth
readout deeper than the actual value. What should I do?
This usually happens if the STC is set to LONG or MID and the bottom is shallow
or SHORT if the bottom is very shallow causing the Auto Range to hook to the
second or third echo from the bottom (since in shallow waters the sound bounces
more times back and forth from the surface to the bottom). Try decreasing the
STC value to SHORT in shallow waters or to switch it to VERY SHORT or OFF.
6.7.2 Auto Range fails, and the digital depth readout displays a very
shallow reading. What should I do?
This usually happens if the STC is off or is set to a low value causing disturbances from
surface clutter to be stronger than bottom echoes. Try increasing the STC value. As
general rule STC has to be set as in shallow waters and L ONG in depth w aters.
6.7.3 Auto Range fails in very deep waters displaying a digital very
shallow depth readout. What should I do?
The Fish Finder capability to detect the bottom decreases as the bottom depth
increase. If the bottom composition is soft as mud, if the sea conditions are bad,
if there are thermoclines or the water is full of materials in suspension it can
further decrease thus causing the digital depth readout to fail. When this happens
the Auto Range algorithm also fails. To recover from this situation it is necessary
to switch to Manual Range mode and to set the Manual Depth mode. When Manual
Depth mode is selected the algorithm that calculates the digital depth readout
searches for the bottom within the range manually selected by the user. At this
point it is necessary to increase manually the Range until the bottom becomes
graphically visible. If the echoes from the bottom are strong enough, the Fish
Finder shall look to the bottom giving a correct depth reading and shall be possible
to return in Auto Range mode. Please note that if one or more of the conditions
that reduce the echoes from the bottom listed above is true the bottom may be
not visible at all, in this situation a strong thermocline or surface clutter may be
interpreted by the Fish Finder as the bottom.
6.8 At a very shallow range upper half of the screen appears
almost completely filled by the surface clutter. How can
I eliminate it?
This is normal in shallow waters. To clean up the surface clutter without degrading
Page 37
39
User Manual
the digital depth readout algorithm functionality there are two modes: 1) if Surface
Declutter = OFF, it is possible to set the STC value to custom setting the STC
length to the same size of the surface clutter, and increasing the STC strength
until the image on the screen cleans up. Please note that in very shallow waters
it is usually better to switch to manual gain mode to reduce gain fluctuation due to
rapidly changing bottom conditions. 2) Using Surface Declutter, increase the Surface
Declutter value until the surface declutter disappears completely.
6.9 Why do I never see fishes in the range between 0 to 0.7
meters?
The minimum range of the Fish Finder is 0.7 meters. In this interval the Fish
Finder can detect neither the bottom nor any target.
6.10 How can I reduce the surface clutter?
You can act by: properly setting the ST C as described at 6.12 and also by increasing
the NOISE LEVEL and reducing the GAIN or the GAIN OFFSET (if you are in auto
gain mode). However please note that a strong attenuation of surface clutter may
also reduce the capability to detect targets.
6.11 The Fish Finder is in Auto Gain mode but the picture
displays too many small targets, what shall I do to reduce
the screen clutter?
Try increasing the NOISE LEVEL or decreasing the GAIN OFFSET.
6.12 In very shallow waters when the Auto Gain mode is
selected there are fluctuations in the bottom profile
width and its color representation. What should I do?
In very shallow waters the environment situation (bottom/water condition) vary
very quickly thus causing the auto gain algorithm to create oscillations while
trying to set optimal GAIN value for each situation. To avoid this it is advisable to
switch to MANUAL GAIN mode and fine tune the GAIN to a fixed setting.
6.13 In very deep waters even setting the Gain to its maximum
value I cannot see the bottom what shall I do?
Try decreasing the NOISE LEVEL. If still the bottom is not visible there is nothing
you can do, the bottom echo is simply too weak to be detected.
