3. FISH FINDER

This chapter is intended to help you understand how STANDARD HORIZON GPS Chart

Plotters with the FF520 connected operate.

The FF520 consists of a high power transmitter, sensitive receiver and a transducer. The

FF520 sends an electrical pulse to the transducer which contains a 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, thermal clines (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.

UNDERSTANDING THE FISH FINDER PAGE

The display on STANDARD HORIZON GPS Chart Plotters shows a history of time of the echoes received by the transducer. The STANDARD HORIZON GPS Chart Plotters have a menu that allows adjustments to receiver sensitivity, depth range and scrolling speed of the

Fish Finder display.

Fish Finder window

It is the 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 fish finder page allows retrieving useful information about what is under the boat. See the following Par. 3.0.0 for more information.

Color Bar

The colored scale located on the left side of the screen that shows the colors used in the Fish finder page to represent the echoes strength. The color on the top of the bar represents the maximum echo strength, while the color on the bottom of the bar represents the minimum echo strength.

Digital Depth

Readout of the current bottom depth.

Water Temperature

Readout of the current water temperature returned by the temperature sensor located in the depth transducer (TEMP1 sensor).

Alarm Bar

Range located on the right side of the depth ruler showing the range outside of which the depth measurement will trigger an alarm condition. Alarm can be set as to alert the user of shallow-water conditions, deep-water conditions or both.

Depth ruler

Vertical graduated bar that is located along the right side of the screen. It is a scale which reflects the depth of the area being displayed.

Page 16 FF520

Variable Depth Marker (VDM)

Horizontal line on to the Fish finder page window with a depth label. Move the

ShuttlePoint knob Up or Down to change the position of the VDM. The label displays the depth of the cursor position. The VDM can be moved to any location pinpointing the depth of a target.

Zoom Bar

Range bar that is located on the left side of the Depth Ruler representing the current zoom range. It is turned on in the un-zoomed window of the Standard/zoomed split view to indicate which portion of the Fish finder page is currently represented in the zoomed window.

A-Scope

Real time representation of fish and bottom features passing through the beam of the transducer. It is drawn as column of horizontal lines whose length and hue is proportional to the echo strength returned. The stronger the echo the larger shall be the line height. The hue depends on the currently selected palette. When the default palette is selected, on the color Chart Plotters the strongest sonar returns will be shown as red and weaker returns will be shown blue.

Operating Frequency

Readout of the selected operating frequency.

3.0.0 Understanding the Fish Finder display

Figure 3.0.0 - The Fish Finder display

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 denser the thermocline shows on the screen. Thermoclines are represented as horizontal stripes of noise. They are very important for

FF520 Page 17

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 FF520. When the echo sounder is set in auto-range mode it is automatically kept in the lower half of the screen.

RANGE MENU

The Range menu allows you to set the Fish Finder working range. The Depth and Shift functions allow the Fish Finder display to be changed from showing information between the bottom of the transducer and the bottom to a range you want to select.

Figure 4.3 - Range sub-menu

The Range options are:

Range Mode : Selects among Manual, Auto Range and Bottom Lock. In Manual Range Mode is possible to set

Shift (the offset from the surface) and depth on which the Fish Finder shall operate. In Auto Range

Mode the Fish Finder determines automatically the range as to keep the bottom visible in the lower bottom of the screen. In this mode, Shift is always set to 0. In Bottom Lock Mode the Fish Finder

Page 26 FF520

Depth

Shift automatically tracks the range around the bottom specified by the Bottom Range value.

: Moves the display from showing the bottom to the depth value entered.

: Shifts the display from the bottom of the transducer to the depth value entered.

Example

Your vessel is in about 57FT of water, however there is fish suspended in 35FT of water.

You want to display to 10FT area around the fish. Shift would be set to 25FT and Depth would be set to 35FT shown in example below.

Figure 4.3a - Example of Depth and Shift

Frequency.

Gain (*)

FF520

Figure 4.5 - Sensitivity sub-menu

: Allows you to control the sensitivity of the unit's receiver. To see more detail, increase the receiver sensitivity by selecting a higher gain percentage. If there is too much detail or if the screen is cluttered, lowering the sensitivity may increase the clarity of the display.

Page 27

STC : Sensitivity Time Constant: it is a time varying gain curve which attenuates the sonar receiver gain in shallow water, increasing the gain gradually as the depth increases. This is for the purpose of filtering out surface clutter.

STC Length

STC Strength

: If STC is Custom, it is possible to change the Length of the Sensitivity Time Constant.

: If STC is Custom, it is possible to change the Strength of the Sensitivity Time Constant.

Surface Noise Filter (**) : This function implements an advanced time varying filter that allows suppressing the surface clutter efficiently while leaving fish targets visible..

NOTE (*)

If the Gain Mode option is set to Auto, the Gain Offset field is active. The default Gain Offset is zero.

If the Gain Mode option is set to Manual, the Gain field is active. When switching from Automatic to Manual mode, the Gain + Offset value is copied into the Manual Gain setting of the receiver.

NOTE (**)

Thus imposing the capability of the Fish Finder to correctly detect the weakest echoes coming from a very deep bottom.

4.7

TRANSDUCER SETUP

This menu allows you to calibrate the speed through the water, water temperature and the keel/prop offset of the transducer.

Keel Offset

FF520

Figure 4.7 - Transducer Setup sub-menu

: The keel offset can be set as to cause the Fish Finder to report either the depth below the keel or the actual water depth from the surface. If we want the Fish Finder to report the depth below the keel, we have to enter a negative value meaning the transducer is mounted above the keel. So if, the range scale is set to e.g. 20 feet, the actual depth below the transducer is 15 feet and a KEEL OFFSET of -3 feet is entered, then the digital depth shall report 12 feet because that is the depth below the keel and the scale on the graphic image shall change so that the range shown is not 0 to 20 feet but -3 to 17 feet. If we want the Fish Finder to report the actual water depth from the surface, we have to enter a positive value meaning the transducer is mounted below the surface. Assume that the transducer is mounted say 5 feet below the water line and we want the unit to report the water depth from the surface,

Page 29

Calibrate Water Speed

Calibrate Water Temp

Calibrate Aux Temp

Set Default we would enter an offset of +5 feet. Then in this example, the digital depth would report a depth of 20 feet (from the surface) and the graphic image scale range would shift from 0 to 20' to 5 to 25'.

: Allows calibrating the value of Water Speed coming from the transducer.

The calibration value, in the range between -10% to +10%, will be applied to the water speed from the transducer.

: Allows the calibration on the Water Temperature sensor. Using the readings from a precise temperature measuring device, insert a positive/negative offset to display the correct temperature.

: Allows the calibration of the Aux Temperature sensor. Using the readings from a precise temperature measuring device, insert here a positive/negative offset to display right value on FF screens.

: Restores the factory settings.

4.8

ALARMS

The Alarms menu allows you to define alarm settings for Shallow Alarm, Depth Alarm and

Temperature Upper/Lower/Rate. To set an Anchor Alarm, enter in a shallow water and depth value above and below your actual anchoring depth. The alarm will sound when the depth becomes shallower or deeper than the settings.

6. TRANSDUCER

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.

TRANSDUCER MOUNTING

6.0.0 Power Boats

Basically there are 2 hull types of powerboats Planing and Displacement. In the pictures shown below the boxes with lines are where the transducer should be installed.

Figure 6.0.0 - Planing

The planing hull allows the boat to rise quickly out of the water, allowing the boat to travel at higher speeds.

Figure 6.0.0a - Displacement

The displacement hull does not ride up on top of the water; rather it pushes through the water.

6.0.1 Sailboats

Most sailboats that use digital depth sounders/transducers are displacement hulls. There are two basic hull types of sailboats:

FF520

Figure 6.0.1 - Fin Keel

Page 35

Figure 6.0.1a - Full Keel

Figure 6.0.1b - Mounting Area

6.0.2 Transducer Types

Since there are many different shapes and sizes of hulls, STANDARD HORIZON offers a range of Depth transducers to fit the vessels requirements.

6.0.3 Low Profile Thru-Hull

If the user is planning to mount a thru-hull transducer first he has to know the dead rise angle where the transducer will be located on the boat. The dead rise is a nautical term that refers to the angle of the hull where the transducer will be mounted (see picture below). Specific transducers are designed to be installed on boats with different dead rises. See Par. 6.1.

= dead rise

Figure 6.0.3 - Dead rise

6.0.4 Transom

POWER BOATS ONLY

The back of a boat is called the transom this is where this transducer is mounted. This transducer has a bracket that is screwed down onto the hull.

6.0.5 Fairing Block

Used when a hull is over 10-15 degrees this type of transducer should be used.

· What makes this transducer different from a Low Profile transducer is that it is used with a fairing block.

· The Fairing block is used to compensate the dead rise of the hull. The fairing block

STANDARD HORIZON offers is made from hard plastic which fits around the transducer.

· To install the transducer and fairing block, the user measures the dead rise of the hull and cuts the fairing block to that angle. One half of the fairing block mounts on the inside while the other part of the fairing block mounts on the outside of the hull.

Page 36 FF520

6.0.6 In-hull

This transducer is epoxyed to the inside of the hull that is not more than 1/2 inch thick and is solid not cored.

7.1

HOW CAN I SET OPTIMAL OPERATING PARAMETERS.

Optimal operating parameters can be set accordingly with the intended use of the Fish

Finder, to quickly get optimal operational parameters for fishing it is may be best to select the FISH preset from the Fish Finder Setup menu, while for cruising it is may be best to select the CRUISE preset.

7.2

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 Fish Finder in full auto mode with the sensitivity settings (GAIN OFFSET,

NOISE level and STC) optimized for displaying the bottom while underway.

· FISH : sets the Fish Finder in full auto mode with the sensitivity setting optimized for fish finding.

7.3

HOW CAN I RESTORE THE FISH FINDER DEFAULT OPERAT-

ING PARAMETERS?

While the Fish Finder page is shown, press [MENU] and move the ShuttlePoint knob to

Transducer Setup and press [ENTER]. Move the ShuttlePoint knob to Set Defaults and press [ENTER]. Press [C

ONFIRM

] on the C175C/CP1000C/CPV350, or on the CP155C/

CP180/CP180i press [ENTER]. Note that this operation set all default settings, not only the working defaults.

7.4

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 the 90% of the cases, however in extreme situations the auto modes mail fail and thus it is necessary to switch to the Manual mode.

7.5

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 (< 5 feet),

Page 40 FF520

when the water is full of materials in suspension, with bad sea conditions.

7.6

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.

7.7

AUTO-RANGE FAILS IN VERY SHALLOW WATERS DIS-

PLAYING 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 the surface to the bottom). Try decreasing the STC value to SHORT in shallow waters or to switch it to VERY SHORT or OFF.

7.8

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 disturbance 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 LONG in depth waters.

7.9

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.

7.10 AT A VERY SHALLOW RANGE UPPER HALF OF THE SCREEN

APPEARS ALMOST COMPLETELY FILLED BY THE SUR-

FACE CLUTTER. HOW CAN I ELIMINATE IT?

This is normal in shallow waters. To clean up the surface clutter without degrading 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

FF520 Page 41

surface clutter, and increasing the STC strenght 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.

7.11 WHY DO I NEVER SEE FISHES IN THE RANGE BETWEEN 0

TO 2 FEET?

The minimum range of the Fish Finder is 2 Feet. In this interval the Fish Finder can detect neither the bottom nor any target.

7.12 HOW CAN I REDUCE THE SURFACE CLUTTER?

You can act by: properly setting the STC as described at 7.10 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.

7.13 THE FISH FINDER IS IN AUTO GAIN MODE BUT THE PIC-

TURE DISPLAY TOO MANY SMALL TARGETS, WHAT SHALL

I DO TO REDUCE THE SCREEN CLUTTER?

Try increasing the NOISE LEVEL or decreasing the GAIN OFFSET.

7.14 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) change 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.

7.15 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.

7.16 GPS CHART PLOTTER SHOWS NO DATA WHEN VIEWING

THE FISH FINDER PAGE

This may be due to the FF520 having an issue. To confirm, listen to the depth transducer for the transmit pulse. If the pulse is not heard the FF520 is defective.
