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 utilizes 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 (455kHz) are used for greatest definition but the operating depth is limited. High frequencies (200kHz) are commonly used on consumer sonar and provide a good balance between depth performance and resolution. Low frequencies (83kHz) 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 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.

531425-1_D - 727 Man_English.qxd 9/30/2005 12:47 AM Page 6

DualBeam PLUS™ Sonar

Your 700 Series™ Fishing System uses a 200/83 kHz DualBeam PLUS™ sonar system with a wide (60°) area of coverage. DualBeam PLUS™ sonar has a narrowly focused 20° center beam, surrounded by a second beam of 60°, expanding your coverage to an area equal to your depth. In 20 feet of water, the wider beam covers an area 20 feet wide. The 20° center beam is focused on the bottom, to show you structure, weeds and cover. The 60° wide beam is hunting for fish in the wide coverage area. DualBeam PLUS™ sonar returns can be blended together, viewed separately or compared side-by-side. DualBeam PLUS™ is ideal for a wide range of conditions

- from shallow to very deep water in both fresh and salt water. Depth capability is affected by such factors as boat speed, wave action, bottom hardness, water conditions and transducer installation.

QuadraBeam™ Sonar

(with optional-purchase QuadraBeamTMtransducer)

Your 700 Series™ Fishing System also supports QuadraBeam™ sonar with the purchase of an additional QuadraBeam™ transducer. QuadraBeam™ sonar provides an extremely wide 90° area of coverage. QuadraBeam™ starts with two 45° 455 kHz beams for a continuous 90° of uninterrupted side to side coverage to 160 feet. These Side Structure locating beams reveal fish and structure to the left and right of your boat near the bottom. For structure directly below your boat, Quadrabeam™ uses DualBeam PLUS™ technology.

WideSide® Sonar

(with optional-purchase WideSide® transducer)

Your 700 Series™ Fishing System also supports WideSide® sonar with the purchase of an additional WideSide® transducer. The WideSide® transducer is a specialized "sidelooking" transducer that is extremely useful for bank fishing or looking for bait fish in open water. The WideSide® transducer uses three different sonar elements that transmit signals to the left, right and straight down from your boat. The downward beam is 200 kHz with a 24° area of coverage. This beam maintains a continuous digital depth readout from the bottom directly beneath your boat. The side beams are 455 kHz with a 16° area of coverage. The side-looking elements can be used independently, or together to locate targets near the surface of the water on either side of your boat.

Views

The views available on your 700 Series™ Fishing System are:

• Sonar View

• Zoom View

• 200/83 kHz Split Sonar View

• Big Digits View

• Circular Flasher View

• Side Beam View

• WideSide® View.

Sonar View is the default view. When the VIEW key is pressed, the display cycles through the available views. When the EXIT key is pressed, the display cycles through the available views in reverse order. Any view can be hidden or displayed as part of the view rotation using the Views Menu tab.

NOTE: When you change any menu settings that affect the sonar, the view will update immediately (i.e. you don’t have to exit the menu to apply the change to the screen). For instance, by switching between "Inverse" and "Structure ID®" from the X-PressTMMenu it is possible to quickly alternate between the two viewing methods.

NOTE: Side Beam View and WideSide® View require the purchase of the QuadraBeam

transducer for the Side Beam View and the WideSide® transducer for the WideSide® View. You can visit our website at www.humminbird.com to order these accessories online or contact our Customer Resource Center at 1-800-633-1468.

Sonar View

Sonar View presents a historical log of sonar returns. Depth is always displayed. Readouts for temperature and speed are automatically displayed if the appropriate accessory is connected. The most recent sonar returns are charted on the right side of the window; as new information is received, the older information is moved across the display to the left. A Digital Depth Readout is displayed in the upper left corner. A scale with Upper and Lower Depth Range readouts appears along the right edge of the Sonar View. The scale indicates the distance from the surface of the water to a depth range sufficient to show the bottom. Depth Range is automatically selected to keep the bottom visible on the display, although you can adjust it manually as well (see Sonar X-Press

Menu). Six additional Digital Readouts display

information from optional-purchase accessories.

These information boxes can be customized to show only the information desired (see Setup Menu Tab, Select Readouts).

NOTE: If the Depth number is flashing, it means that the unit is having trouble locating the bottom. This usually happens if the water is too deep, the transducer is out of the water, the boat is moving too fast, or for any other reason that the unit can’t accurately receive continuous data.

Understanding Sonar History

It is important to understand the significance of the 700 Series™ Fishing System 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.

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 either

Inverse (default), WhiteLine®, Structure ID®, or Bottom Black. See Sonar X-Press

Menu: Bottom View for details on how to set the bottom 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 always 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 - RTS® Window).

Freeze Frame

Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the screen and a cursor will be displayed on the screen. The cursor can be positioned on the display using the 4-WAY Cursor Control key to determine the depth of any sonar return. The RTS® Window continues to update in Freeze Frame. In addition, see the effects of menu setting changes with Instant Image Update. Pressing EXIT will exit Freeze Frame and the display will start to scroll. Freeze Frame is available in Sonar, Sonar Zoom and 200/83 kHz Split Sonar Views.

The Narrow RTS® Window indicates the sonar intensity through the use of grayscale. The grayscale used matches the bottom view grayscale setting used in the sonar history window (i.e. Inverse, Structure ID®, 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 provides an indication of 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 make use of grayscale.

531425-1_D - 727 Man_English.qxd 9/30/2005 12:47 AM Page 16

Sonar Zoom View

Sonar Zoom View increases the displayed resolution to separate sonar returns that are very close together, such as those caused by fish suspended close to the bottom or within structure. In Zoom View, the display is split to show a narrow slice of the full range view on the right and the zoomed view on the left. The full range view on the right also contains the Zoom Preview Box that shows what part of the full range view is shown in zoom view on the left; the Zoom Preview Box tracks the bottom in the full range view.

As the depth changes, the zoomed view updates automatically to display a magnified image of the bottom. The Zoom Preview Box shows where the zoomed view is in relation to the full range view. The Zoom Level, or magnification, is displayed in the lower left corner and can be changed to suit conditions (see Sonar

X-Press

Menu: Zoom Level). Upper and Lower Zoom Depth Range numbers indicate

the depth of the water which is being viewed.

Digital depth is displayed in the upper left hand corner. The digital readouts in the Sonar Zoom View cannot be customized; therefore, information such as water temperature and voltage are unavailable in the Sonar Zoom 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.

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. Any targets such as fish, structure and thermoclines will be shown using the Structure ID® method.

WideSide® View

(with optional-purchase WideSide® transducer)

WideSide® View is only available if you have connected a WideSide® transducer accessory and when Transducer Select is set to WideSide® (see Sonar Menu Tab: Transducer Select). The WideSide® transducer requires a separate purchase. The WideSide® View displays information from the 455 kHz WideSide® transducer. Three views are available: Left, Right and Both. The default view is Both. Information from both the left and right beams are displayed simultaneously. The depth of the water beneath the boat is always displayed. A bottom contour may be present while bank fishing or fishing river channels. When fishing in the open water, a bottom contour will not be present, and only sonar returns from either debris or fish will be displayed.

The QuadraBeam™ transducer requires a separate purchase. This view shows sonar information from both the left and right 90° 455 kHz beams and the 200 kHz down-looking beam in one view. The top portion of the display presents a historical log of sonar returns from the 200 kHz down-looking sonar. The bottom portion of the display presents a historical log of sonar returns from the 455 kHz right- and left-looking sonar. New information appears at the top, and scrolls down the display.

The sonar information from the side-looking beams reveals bottom contour, structure and fish similar to the down-looking beam, but the area covered is to the left and right of the area shown in the down-looking portion, so you actually see more of the bottom. The distance covered by the right and left 90° beams is based on the depth setting for the down-looking beam, up to a maximum of 160 feet.
