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.

How Sonar Works

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:

How Sonar Works

• 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.

Side Imaging® Sonar

Your 700 Series™ Fishing System uses Side Imaging® sonar to provide a wide yet precise survey of a large area of water, including detailed bottom topography and fish-attractingstructure orientation. The Side Imaging® transducer returns are processed into an image similar to an aerial photograph. Typically, the Side Imaging® sonar searches an area that is 240 feet wide to each side, 480 feet total side coverage, with a depth limitation of 150 feet. See What’s on the Side Imaging® Display for more information.

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. 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.

(with optional-purchase QuadraBeam PLUS™ transducer)

Your 700 Series™ Fishing System also supports QuadraBeam PLUS™ sonar with the purchase of an additional QuadraBeam PLUS™ transducer. QuadraBeam PLUS™ sonar provides an extremely wide 90° area of coverage. QuadraBeam PLUS™ starts with two fan-shaped 35° 455 kHz Side Structure locating sonar beams to spot fish, bait, and structure to the left and right of the boat over an area of the bottom that’s always equal to twice your depth. For a detailed view below the boat, QuadraBeam PLUS™ uses DualBeam PLUS™ technology, with precision 20° and wide 60° beams. QuadraBeam PLUS™ finds more fish faster and can even tell you where to put your bait by showing if fish are to the left, right, or directly beneath your boat.

How Sonar Works

Universal Sonar 2

(compatible w/ optional-purchase Minnkota trolling motors)

Your 700 Series™ Fishing System supports Universal Sonar 2, a state-of-theart, integrated and protected transducer that is built into the lower unit of Minnkota trolling motors. With Universal Sonar 2, all wiring is concealed inside the indestructible composite shaft—out of sight and out of harm’s way, with no clamps, ties, or exposed wires. Universal Sonar 2 features new temperature sensing and the performance of DualBeam PLUS™ technology (available with all Humminbird® DualBeam PLUS™ models). An expanded view and greater bottom detail gives you a totally new perspective of the water below, along with optimal sonar performance to help you find fish.

How Sonar Works

How GPS and Cartography Work

Your 700 Series™ Fishing System also supports GPS and chartplotting. It uses GPS and sonar to determine your position, display it on a grid, and provide detailed underwater information. The Global Positioning System (GPS) is a satellite navigation system designed and maintained by the U.S. Department of Defense. GPS was originally intended for military use; however, civilians may also take advantage of its highly accurate position capabilities, typically within +/- 4.5 meters, depending on conditions. This means that 95% of the time, the GPS receiver will read a location within 4.5 meters of your actual position. Your GPS Receiver also uses information from WAAS (the Wide Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are available in your area.

GPS uses a constellation of over 24 satellites that continually send radio signals to the earth. Your present position is determined by receiving signals from up to 16 satellites and measuring the distance from the satellites.

All satellites broadcast a uniquely coded signal once per second at exactly the same time. The GPS receiver on your boat receives signals from

satellites that are visible to it. Based on time differences between each received signal, the GPS receiver determines its distance to each satellite. With distances known, the GPS receiver mathematically triangulates its own position. With once per second updates, the GPS receiver then calculates its velocity and bearing.

How GPS and Cartography Work

The GPS Receiver included with your 700 Series™ Fishing System allows you to combine easy-to-use FishingGPS® chartplotter and navigation capabilities with advanced fishfinding.

The following GPS functionality is currently supported by the 700 Series™ Fishing System when it is connected to the included GPS receiver:

• View current position

• View current track (breadcrumb trail)

• View precision speed and heading from your GPS receiver

• Save tracks, waypoints, and routes

• Travel a route and navigate from one waypoint to the next.

Your 700 Series™ supports Navionics® Gold, HotMaps™ and HotMaps™ Premium on MMC or SD card media. You can insert optional-purchase cards in the (MMC)/SD slots on your control head to access additional detailed maps. See Multi-Media Card (MMC)/SD Slot for more information.

NOTE: Your 700 Series™ supports Navionics® Gold, HotMaps™, and HotMaps™ Premium. Your 700 Series™ does not support Navionics® Classic Charts or Platinum™ Cartography.

Your unit also comes with a built-in UniMap™ with a more detailed map of North America (Domestic models) or a more detailed map of Europe and Southeast Asia, including Australia and New Zealand (International models).

Your 700 Series™ uses the GPS Receiver to determine the position of the boat automatically, and it uses the zoom level settings on a particular view to select the best chart to display. See Chart View: Viewing Cartography for more information.

How GPS and Cartography Work

What’s on the Side Imaging® Display

Side Imaging® displays a number of easily recognizable features that allow for bottom composition determines the intensity of the sonar return. For example, their relative density. Upward slopes that face the transducer reflect sonar a number of easily recognizable features on the Side Imaging® display that following items:

Top of the Display - Information from the side beams are displayed at the top of the screen. As new information is received, the historical data scrolls down the screen. For the most current information, watch the top of the screen.

Freeze Frame & Zoom - Use the 4-WAY Cursor Control key to move the cursor to an area on the screen, and press the ZOOM+ key to see the sonar returns in greater detail.

Clouded Area - may indicate a bait ball and White Streaks may indicate fish.

Bottom Return - hard bottom

Topography Changes - The light part

of the screen shows where the beam is hitting hard bottom or rising terrain. The dark part of the screen indicates soft bottom (sand, mud) or descending terrain.

Depth - water depth; canbe set to alarm when the water becomes too shallow.

What’s on the Side Imaging® Display

accurate interpretation of bottom contour and structure. For Side Imaging®, the rock and gravel provide a clearer sonar return than mud and sand because of better than downward slopes that face away from the transducer. You can find allow for accurate interpretation of bottom contour and structure, including the

Side Imaging® Range - Images shown on the right side of the screen are located on the right side of your boat, and images shown on the left side of the screen are located on the left side of your boat. In this picture, the sonar is pinging 150 feet on each side.

The water column shows the relative depth of the water under the boat at a given time. Variations in the width of the water column show variations in the distance to the bottom as the boat passes over.

Shadows result from a lack of reflected sonar from a particular area, and can be more valuable for interpretation than the sonar reflected by the object itself. Use shadows to help you see the image in 3 dimensions, oriented in space. You can gain insight into the actual shape of an object, or the depth to which it has sunk into the bottom, through shadows on the display. Objects standing on the bottom cast a sonar shadow. The longer the shadow, the taller the object. Fish also cast shadows. You can use the shadow to interpret how close the fish is to the bottom.

What’s on the Side Imaging® Display

Understanding the Side Imaging® Display

It is important to understand how Side Imaging® technology produces the display. The images you see on the display are produced using sonar technology. The special transducer projects three distinct beams – one beam facing down and two beams pointing out to the side. The “down beam” is aimed directly below the boat and provides conical coverage. The “side beams” are aimed at right angles to the path of the boat. The side beam coverage is very thin from front to back, yet very wide top to bottom.

Side Beams extend to the right and left of the transducer. The side beams are very thin front to back, yet very wide top to bottom.

Down Beam - a cone shaped beam that pings directly below the boat

NOTE:Drawing shown for illustration purposes only and may not meet technical specifications.

The narrow aspect (front to back) of the beam illuminates a small strip of the bottom perpendicular to the direction of the boat. Each time the unit “pings,” a strip of data representing all the echoes received by the transducer are put together on the display to form the image that you see.

What’s on the Side Imaging® Display

The rows closest to the boat icon at the top of the view are the most recent sonar data. The information is scrolled down the screen as new data, drawn at the top of the screen, becomes available.

For Best Side Imaging® Performance

• Boat speed: 2 to 6 mph

• Straight line navigation

• Minimum turning time and wave turbulence

See Side Imaging Tips for more information.

The side beams operate at a frequency of 455 kHz. It is important to understand that when the boat turns, the strips to one side will begin to overlap and the strips on the other side will fan out, providing some distortion to the image. Side beams look out 240 feet to each side, with a total side coverage of 480 feet, with a depth limitation of 150 feet, depending on the contour of the bottom.

Your Side Imaging® transducer also provides traditional sonar imaging at 200/83 kHz. Total coverage under the boat is 180°.

455 kHz provides maximum coverage with 180° total beam width

See www.humminbird.com and www.sideimaging.com for a side imaging sonar tutorial and additional information.

What’s on the Side Imaging® Display

Side Imaging® Technology: How It Works

Side Imaging® sonar uses two very precise sonar beams that are directed to either side of the boat and “illuminate” the bottom contour, structure, and fish, and display results in a “picture-like” image.

• Side beams are extremely narrow from front to back, and provide “thin slices” of the bottom for high resolution imaging.

• Side beams look out to a range of 240 feet to each side, with a total side coverage of 480 feet, with a depth limitation of 150 feet.

The main benefit of Side Imaging® sonar to anglers is that it provides an overall survey of a large area of water. This gives you a better understanding of the bottom topography and how structure is oriented for more efficient fishing. Saltwater anglers pick up precise details of popular fishing structure like wrecks, reefs, humps and drop-offs, as well as being able to spot bait balls in open water. Freshwater anglers can see fish-attracting structure such as timber, stumps, rocks, and creek beds.

What’s on the Side Imaging® Display

Side Imaging Display View

Side Imaging®: For Best Performance

Use the following Side Imaging® tips and examples to help you interpret the Side Imaging® display.

For Best Side Imaging® Performance

• Boat speed: 2 to 6 mph

• Straight line navigation

• Minimum turning time and wave turbulence

Imaging Tips

Boat speed: Side Imaging® is best performed at boat speeds between 2 to 6 mph. If the boat is stationary, the same information is displayed over and over. If the boat is moving very quickly, there will be gaps between the strips of information. The best boat speed to use will depend on the side range selected. Slower speeds are good for longer ranges, while faster speeds can be used at shorter ranges.

Boat navigation: It is important to understand that when the boat turns, successive beam strips to one side will begin to overlap and the strips on the other side will fan out, providing some distortion to the image. Because of this, the best imaging performance is produced by straight line navigation and minimal side-to-side boat motion (i.e. wave induced, etc.) This applies to navigation by either the main engine or the trolling motor. Minimize turning time and avoid wave action that induces large side-to-side rocking of the boat. For example, if there is a lot of wave activity, try to move the boat so that it is perpendicular to the waves instead of parallel with the waves in order to minimize the side-to-side rocking of the boat.

Beam Coverage: When there is an area directly under the boat that does not have SI beam coverage, this area will be covered by the standard 200/83 kHz down-looking beam and displayed in the Sonar views. The net effect of this, on the display, is that a single object may appear as two separate entities, when in reality, it is one continuous object. See Submerged Bridge: A Closer Perspective and the Submerged Bridge: Alternative Perspective illustrations

for examples of this.

What’s On the Sonar Display

The 700 Series™ Fishing System can display a variety of useful information about the area under and adjacent to your boat, including the following items:

Depth - water depth; can be set to alarm when the water becomes too shallow.

Temperature - water surface temperature.

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.

Second Sonar Return - when the sonar signal bounces between the bottom and the surface of the water and back again. Use the appearance of the second return to determine bottom hardness. Hard bottoms will show a strong second return, while soft bottoms will show a very weak one or none at all.

Cursor Dialog Box - indicates cursor depth on the display and the depth of the bottom directly below the cursor. The Latitude and Longitude of the cursor position, the distance to travel to the cursor position and the bearing to the cursor position is shown with a GPS receiver. A waypoint can be marked at the cursor position for later retrieval and use with a GPS receiver.

NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either device is connected to the 700 Series™ Fishing System. If both devices are connected, then only the information from the GPS receiver will be displayed on the view.
