• Page 10: How Sonar Works

  How Sonar Works Sonar technology is based on sound waves. The 700 Series™ Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 700 Series™ Fishing System sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object;…

• Page 11
  When all the echoes are viewed side by side, an easy to interpret “graph“ of the bottom, fish, and structure appears. The sound pulses are transmitted at various frequencies depending on the application. Very high frequencies (455 kHz) are used for greatest definition but the operating depth is limited.

• Page 12: 3D Sonar

  3D Sonar Your Fishing System uses a six- element transducer that transmits at 455 kHz and is capable of reaching depths of 240 ft (75 m). Each transmitted beam is symmetrical and 16 degrees in width. The six beams are lined up next to each other to provide a total coverage of 53 degrees from side to side, and 16 degrees from front to back.

• Page 13: Sonar

  2D Sonar Your Fishing System also has the capability of displaying traditional 2-dimensional sonar information from either a 455 kHz beam or an 83 kHz beam. The 455 kHz single beam has the advantage of providing increased sonar resolution but is limited to a depth capability of 240 ft (75 m).

• Page 14: What’s On The 3D Sonar Display

  What’s on the 3D Sonar Display In 3D views, your Fishing System can display a variety of useful information Depth — Water depth can be set to alarm when the water becomes too shallow.

  about the area under your boat, including the following items: Bait Ball Hollow Fish Symbol (see Fish ID+™) Thermoclines — Layers of water with different temperatures that appear at different depths and different times of the year. A thermocline typically appears as a continuous band of gray levels moving across the display at the same depth.

• Page 18: Understanding The 2D Sonar Display

  Understanding the 2D Sonar Display It is important to understand the significance of the display. The display does not show a literal 3-dimensional representation of what is under the water. Each vertical band of data received by the control head and plotted on the display represents something that was detected by a sonar return at a particular time.

• Page 19: Switchfire

  SwitchFire™ SwitchFire™ controls how the sonar returns are displayed in the Sonar Views. SwitchFire™ settings are available in the Sonar Menu Tab. To see the maximum sonar information available within the transducer beam so more fish arches and better jig tracking are shown, choose Max Mode. To see less clutter and more fish size accuracy interpreted from the transducer beam, choose Clear Mode.

• Page 20: Bottom Presentation

  Bottom Presentation As the boat moves, the unit charts the changes in depth on the display to create a profile of the Bottom Contour. The type of bottom can be determined from the return charted on the display. A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the display.

• Page 21
  Inverse is a method where weak returns are shown with dark pixels and strong returns with lighter pixels. This has the benefit of ensuring that weak signals will be clearly visible on the display. Structure ID® represents weak returns as light pixels and strong returns as dark pixels.

  Thermoclines Water layer(s) of distinctly different temperatures that create a sonar reflection due to the density of the differing water temperatures. Typically a thermocline will appear as a continuous band across the display at some distance above the bottom contour. Thermoclines are of interest to anglers because fish will suspend above or below the thermocline as they seek the optimum temperature and oxygen levels.

How Sonar Works

Sonar technology is based on sound waves. The 700 Series™ Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer.

Your 700 Series™ Fishing System sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object; it then uses the reflected signal to interpret location, size, and composition of an object.

Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that your boat can “outrun“ this sonar signal.

SONAR is an acronym for SOund and NAvigation Ranging. Sonar uses precision sound pulses or “pings“ which are emitted into the water in a teardrop-shaped beam.

The sound pulses “echo“ back from objects in the water such as the bottom, fish, and other submerged objects. The returned echoes are displayed on the LCD screen. Each time a new echo is received, the old echoes are moved across the LCD, creating a scrolling effect.

When all the echoes are viewed side by side, an easy to interpret “graph“ of the bottom, fish, and structure appears.

The sound pulses are transmitted at various frequencies depending on the application. Very high frequencies (455 kHz) are used for greatest definition but the operating depth is limited. High frequencies (200 kHz) are commonly used on consumer sonar and provide a good balance between depth performance and resolution. Low frequencies (83 kHz) are typically used to achieve greater depth capability.

The power output is the amount of energy generated by the sonar transmitter. It is commonly measured using two methods:

•Root Mean Square (RMS) measures power output over the entire transmit cycle.

•Peak to Peak (PtP) measures power output at the highest points.

The benefits of increased power output are the ability to detect smaller targets at greater distances, ability to overcome noise, better high speed performance and enhanced depth capability.

3D Sonar

Your Fishing System uses a sixelement transducer that transmits at 455 kHz and is capable of reaching depths of 240 ft (75 m). Each transmitted beam is symmetrical and 16 degrees in width. The six beams are lined up next to each other to provide a total coverage of 53 degrees from side to side, and 16 degrees from front to back.

Using multiple narrow beams together gives you a wide area of coverage for terrain interpretation and fish location, without sacrificing the detail only a narrow beam can provide. Your Fishing System gathers information from a continuous series of these returned signals. It then interprets this information to create a detailed 3-dimensional view of the terrain passing beneath your boat as you travel across the water.

NOTE: Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

2D Sonar

Your Fishing System also has the capability of displaying traditional 2-dimensional sonar information from either a 455 kHz beam or an 83 kHz beam.

The 455 kHz single beam has the advantage of providing increased sonar resolution but is limited to a depth capability of 240 ft (75 m). The 83 kHz single beam sonar has the advantage of providing sonar information to 1000 ft (330 m) but provides less resolution than the 455 kHz beam.

NOTE: Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions, and transducer installation.

What’s on the 3D Sonar Display

In 3D views, your Fishing System can display a variety of useful information

Depth — Water depth can be set to alarm when the water becomes too shallow.

Temperature — Water surface temperature.

Bottom Contour — Shows the shape of the bottom derived from depth measurements on 6 beams. 3 bottom styles are available; the front edges of the bottom contour are outlined to create a visual anchor. The width of the bottom covered is approximately equal to the depth.

Timer — Elapsed time with Temp/Speed

Accessory or GPS Receiver.

Distance — Distance traveled with

Temp/Speed Accessory or GPS Receiver.

Average Speed — Average speed reading with Temp/Speed Accessory or GPS Receiver.

Speed — If a Temp/Speed accessory or GPS Receiver is attached, the Fishing System can display the speed of the boat and can keep a Triplog of nautical or statute miles traveled.

NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if the information from the GPS receiver will be displayed on the view.

about the area under and adjacent to your boat, including the following items:

Boat/Direction Arrow — A simple, solid 3D boat is drawn when the Upper Depth Range is 0. A solid 3D arrow is drawn when the Upper Depth Range is not 0.

Upper and Lower Depth Range

Fish ID+™ — A fish icon will be shown at the derived position of the fish. Six fish icon styles will be used to indicate the primary beam in which the fish was found. Left-facing fish indicate fish off the port side of the boat, while rightfacing fish indicate fish off the starboard side. Each fish icon is available in three different sizes. Larger fish icons are used to represent stronger returns. The icons used in the 2D Sonar View are identical to the icons used in the 3D Sonar View.

Battery Voltage — The voltage of the boat’s battery; can be set to alarm if the voltage falls below a certain point.

Frame — Provides a reference for bottom and Fish ID information. A Range of frame styles are available, from simple to complex.

Thermoclines — Layers of water with different temperatures that appear at different depths and different times of the year. A thermocline typically appears as a continuous band of gray levels moving across the display at the same depth.

Structure — Where fish may be hiding.

Fish — The Fishing System displays fish as arches and/or fish icons, and can be set to alarm when a fish of a certain size is detected. When a target is detected, a Fish ID+™ symbol appears on the display with the depth displayed above it. The size of the symbol indicates the intensity of the sonar return. The unit will clearly show schools of Bait Fish as ”clouds” of different shapes and sizes, depending on the number of fish and boat speed.

Understanding the

2D Sonar Display

It is important to understand the significance of the display. The display does not show a literal 3-dimensional representation of what is under the water. Each vertical band of data received by the control head and plotted on the display represents something that was detected by a sonar return at a particular time. As both the boat and the targets (fish) may be moving, the returns are only showing a particular segment of time when objects were detected, not exactly where those objects are in relation to other objects shown on the display.

The returned sonar echoes are displayed on the screen. As a new echo is received, the historical data scrolls left across the view.

Real Time Sonar (RTS™) Window

A Real Time Sonar (RTS™) Window appears on the right side of the display in the Sonar View only. The RTS Window™ updates at the fastest rate possible for depth conditions and shows only the returns from the bottom, structure, and fish that are within the transducer beam. The RTS Window™ plots the depth and intensity of a sonar return (see Sonar Menu Tab: RTS Window™).

The Narrow RTS Window™ indicates the sonar intensity through the use of grayscale. The grayscale used matches the Bottom View grayscale setting (Inverse, StructureID®, WhiteLine™, Bottom Black) . The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale.

The Wide RTS Window™ indicates the sonar intensity through the use of a bar graph. The length of the plotted return indicates whether the return is weak or strong. The depth of the sonar return is indicated by the vertical placement of the return on the display depth scale. The Wide RTS Window™ does not use grayscale.

SwitchFire™

SwitchFire™ controls how the sonar returns are displayed in the Sonar Views. SwitchFire™ settings are available in the Sonar Menu Tab.

To see the maximum sonar information available within the transducer beam so more fish arches and better jig tracking are shown, choose Max Mode.

To see less clutter and more fish size accuracy interpreted from the transducer beam, choose Clear Mode. See Sonar Menu Tab: SwitchFire™ for more information.

Freeze Frame and Active Cursor

Press any arrow on the 4-WAY Cursor Control key, and the screen will freeze and a cursor will be displayed. Use the 4-WAY Cursor Control key to move the cursor over a sonar return, and the depth of the sonar return will be displayed in the cursor dialog box.

NOTE: In 2D Sonar Views, the RTS Window™ continues to update in Freeze Frame.

To return to a scrolling display and exit Freeze Frame, press the EXIT key. Freeze Frame is available in the Sonar and Sonar Zoom Views.

Instant Image Update

Instant Image Update — You can change a variety of sonar menu settings (such as Sensitivity or Upper Range), and the adjustments will be shown instantly on the screen.

Bottom Presentation

As the boat moves, the unit charts the changes in depth on the display to create a profile of the Bottom Contour. The type of bottom can be determined from the return charted on the display. A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky Bottoms have a broken, random appearance.

The sonar returns from the bottom, structure, and fish can be represented as

Inverse, Structure ID®, WhiteLine™, or Black (Bottom Black). See

Sonar X-Press™ Menu: Bottom View to set the Bottom View.

Inverse is a method where weak returns are shown with dark pixels and strong returns with lighter pixels. This has the benefit of ensuring that weak signals will be clearly visible on the display.

Structure ID® represents weak returns as light pixels and strong returns as dark pixels. This has the benefit of ensuring that strong returns will be clearly visible on the display.

WhiteLine™ highlights the strongest sonar returns in white resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display.

Black (Bottom Black) displays all pixels below the bottom contour as black, regardless of signal strength. This has the benefit of providing a high contrast between the bottom and other sonar returns on the display.

3D Sonar View

3D Sonar View displays a 3-dimensional representation of the bottom. The sonar returns from each of the six elements are combined to create this 3- dimensional, wire-frame image. This graphic depiction of the bottom provides you with an effective tool for understanding the terrain beneath the boat.

•Digital Readouts: Depth is always displayed in the upper left hand corner. Temperature and speed are displayed if the temp/speed paddle wheel is connected or if a GPS receiver is connected.

•Location: The location of your boat in relation to the on-screen information is represented by the boat icon.

•Sonar Returns: The most recent sonar returns are charted on the upper right side of the screen and move to the lower left as new information is received. The width of coverage is approximately equal to the depth.

•Fish ID+: If a return meets certain criteria, one of 18 kinds of fish symbols will be assigned. There are three different size fish symbols to indicate the intensity of the return and each of the six beams has a unique set of fish symbols (see Sonar Menu Tab: Fish ID+™ for more information).
