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.

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-byside. 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 PLUS Sonar

(with optional-purchase QuadraBeam PLUS transducer)

455 kHz

200 kHz

83 kHz

90 Total Coverage Bottom Coverage = 2 x Depth
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 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 thats 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.

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.

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). Five 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).

The Menu System
The menu system is divided into easy-to-use menu modules. The main components of the menu system are: Start-Up Options Menu - Press the MENU key during the power up sequence to view the Start-Up Options menu. X-Press Menu - The X-Press Menu allows you to access the settings that are changed frequently without having to navigate through the whole menu system. Press the MENU key once to display the X-Press Menu. When you select a menu item from the X-Press Menu, the menu will collapse, leaving only the menu choice on the screen. Use the UP or DOWN Cursor keys to reactivate the X-Press Menu.

X-Press Menu

NOTE: The X-Press Menu choices will vary depending on which view is active when you press the MENU key, as well as whether you are in Normal or Advanced User Mode.
Main Menu Tabs - Less frequently-adjusted menus are grouped into the Main Menu System. The Main Menu system is organized under the following tab headings to help you find a specific menu item quickly: Alarms, Sonar, Setup, Views, and Accessories. Press the MENU key twice for the Main Menu, then use the 4-WAY Cursor LEFT or RIGHT key to select a tab, and use the DOWN or UP key to select a specific menu item under that tab, then Main Menu System use the LEFT or RIGHT keys again to change a Normal User Mode menu setting. Press the EXIT key to move quickly to the top of the tab. A down arrow at the bottom of a menu means that you can scroll to additional menu choices using the DOWN Cursor key. A right or left arrow on a menu choice means that you can use the RIGHT or LEFT Cursor keys to make changes or to see more information.

To adjust the Upper Range: 1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar X-Press Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Upper Range setting. (0 to 1490 feet or 0 to 497 meters [International Models only], Default = 0)

Lower Range

Lower Range sets the deepest depth range that will be displayed. Automatic is the default setting. When in automatic mode, the lower range will be adjusted by the unit to follow the bottom. Selecting a specific setting locks the depth range into Manual mode. Use both Upper and Lower Range together to view a specific depth range manually when looking for fish or bottom structure. M will be displayed in the lower right corner of the screen when you start manually adjusting the Lower Range to indicate that you are in Manual mode.
For example, if you are fishing in 60 feet of water but are only interested in the first 30 feet (surface to a depth of 30 feet) you should set the Lower Depth Range limit to 30. The display will show the 0 to 30 foot range, allowing you to see a more detailed view than you would see if the display went all the way to the bottom. NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower Range regardless of the manual settings entered.
To adjust the Lower Range: 1. Highlight Lower Range on the Sonar X-Press Menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Lower Range setting. (AUTO, 10 to 1500 feet, 3 to 500 meters [International Models only], Default = AUTO)

Side Beam Range

Side Beam Range sets the deepest range that will be displayed in the WideSide View. The range must be set manually to keep the bottom visible on the display. If the Side Beam Range is set too deep for current depth conditions the sonar information will become compressed on the display and valuable detail will be lost. A WideSide transducer must be connected to your Fishing System. Side Beam Range menu choice is available when Transducer Select is set to WideSide (see Sonar Menu Tab: Transducer Select) and can only be accessed from the WideSide view.
NOTE: The Side Beam Range requires the purchase of the WideSide transducer. You can visit our website at www.humminbird.com to order this accessory online or contact our Customer Resource Center at 1-800-633-1468.

Fish ID+

Fish ID+ uses advanced signal processing to interpret sonar returns, and will display a Fish Symbol when very selective requirements are met. When a fish is detected, a fish icon and its depth are displayed above the return that has been classified as being a fish. Three different fish size icons represent the intensity of the sonar return, and provide an indicator of relative fish size. DualBeam PLUS sonar models represent targets detected in the 200 kHz narrow beam as Orange Fish Symbols, and represent targets detected in the 83 kHz wide beam as Blue Fish Symbols.
200 kHz, Narrow Beam Orange Fish Symbols 83 kHz, Wide Beam Blue Fish Symbols
When Fish ID+ is turned off, the Fishing System shows only the raw sonar returns on the display. These returns will often result in "arches" forming on the display, indicating potential targets. Due to the transducer beam angle, the distance to a fish decreases as the fish moves into the beam, and then increases as it moves out again, creating a Fish Arch when this distance change is shown on the display. Boat speed, chart speed, and the position of the fish within the sonar beam greatly affect the shape of the arch.
Transducer Cone and Fish Arches
To turn Fish ID+ on or off: 1. Highlight Fish ID+ on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Fish ID+ setting On or Off. (Off, On, Default = Off) 45

Fish ID Sensitivity

Fish ID Sensitivity adjusts the threshold of the Fish ID+detection algorithms. Selecting a higher setting allows weaker returns to be displayed as fish. This is useful for identifying smaller fish species or baitfish. Selecting a lower setting displays fewer fish from weak sonar returns. This is helpful when seeking larger species of fish. Fish ID Sensitivity is used in conjunction with Fish ID+. Fish ID+ must be On for Fish ID Sensitivity to affect the ability of the Fishing System to identify sonar returns as fish. To change the Fish ID Sensitivity setting: 1. Highlight Fish ID Sensitivity on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID Sensitivity setting. (Low = 1, High = 10, Default = 5)
RTS Window sets the RTS Window to either Wide or Narrow, or turns it off in the Sonar View. The RTS Window always updates at the fastest rate possible and only displays returns that are within the transducer beam. (See Real Time Sonar (RTS) Window for additional detail).
RTS Window (Wide) RTS Window (Narrow) RTS Window (Off)
To change the RTS Window setting: 1. Highlight RTS Window on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the RTS Window setting. (Wide, Narrow, Off, Default = Narrow) 46

NOTE: In salt water, what would be considered a large fish might be 2 to 10 times bigger than a large fish in fresh water (depending on the type of fish you are seeking). The salt water setting allows for a greater range in fish size adjustment to account for this. Also, make sure that the Water Type is set accurately, especially in salt water, as this affects the accuracy of deep water depth readings.
To change the Water Type setting: 1. Make sure you are in Advanced User Mode, then highlight Water Type on the Sonar main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Water Type setting. (Fresh, Salt, Default = Fresh)

Transducer Select

Transducer Select allows you to select which transducer you want to use (the Fishing System comes with a DualBeam PLUS transducer, and also supports the optional-purchase QuadraBeam PLUS and WideSide transducers.) To change the selected Transducer: 1. Highlight Transducer Select on the Sonar Main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the transducer selected. (DualBeam, QuadBeam, WideSide, Universal Sonar 2, Default = DualBeam)
From any view, press the MENU key twice to access the Main Menu System. The Alarms tab will be the default selection.
NOTE: When an alarm is triggered, you can silence it by pressing any key. The alarm will be silenced, and will not be triggered again until a new instance of the alarm condition is detected.

Alarms Menu

Depth Alarm
Depth Alarm sounds when the depth becomes equal to or less than the menu setting. To change the Depth Alarm setting: 1. Highlight Depth Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Depth Alarm setting. (OFF, 1 to 100 feet, or 0.5 to 30 meters [International Models only], Default = OFF)

Fish ID Alarm

Fish ID Alarm sounds when the Fishing System detects fish that correspond to the alarm setting. Fish ID Alarm will only sound if Fish ID+ is on.
For example, if you've set the Fish ID Alarm to sound for Large fish only, the Fish ID alarm will sound when a large-sized fish is detected.
To change the Fish ID Alarm setting: 1. Highlight Fish ID Alarm on the Alarms main menu. 2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID Alarm setting. (Off, All, Large/Medium, Large, Default = Off)

Alarm Tone

Glossary

Sonar Terms: Alarm, Depth: Depth Alarm is a user-controllable, audible alert that sounds when depth is less than or equal to the setting.
Alarm, Temperature: Temperature Alarm is a user-controllable, audible alert that sounds when the water surface temperature equals the setting. Backlight: Backlight is a user-controllable illumination for the LCD for night and low light use. Beam (Sonar Beam): A sonar beam is the wide, cone-shaped projection of sound waves formed as sound travels underwater. See Cone Angle. Big Digits View: Big Digits View is a Humminbird feature that displays the sonar graph and enlarged digital readouts for easy reading from a distance. This is a great tool when monitoring the digital depth is important - such as with higher boat speeds, or when viewing the unit from a distance. When speed input is available, the Big Digits View also shows the TripLog. See TripLog. Bottom Black: Bottom Black is a Humminbird feature that "fills in" the area of the display below the bottom contour. Bottom Black is preferred by some anglers because of its high contrast and easy readability, even though it can obscure bottom hardness information. Bottom Contour: Bottom Contour is the profile of the bottom graphed to the display as the depth changes. Bottom Hardness: Bottom Hardness is the density (or composition) of the bottom, which can often be determined by interpreting the main sonar return. Varying levels of hardness can be determined by interpreting the "thickness" of the sonar return. Hard returns appear thin and black, softer returns appear thicker and less black. It is important to note that a sonar return from a sloping bottom can have the appearance of a softer bottom. Cavitation: Cavitation is the effect of air bubbles created as the propeller rotates and the boat moves through the water.
Chart Speed: Chart Speed is a user-controllable feature that sets the speed at which sonar information moves across the display. A faster setting displays sonar information from more pings and shows more detail, but the information moves quickly across the display: a slower setting permits viewing of more sonar history, but does not display as much detail. The best setting is often the user's personal choice. Cone Angle: The cone angle is the angular measurement of the sonar beam at a specific dB down point (i.e. -10 dB). See dB Down Point. Customizable Digital Readouts: Customizable Digital Readouts is a Humminbird feature that permits the user to select the specific digital information that appears in the main Sonar view (i.e. Speed, Temperature, Barometric Pressure, TripLog, etc.) Dead Zone: The dead zone is the area of the sonar beam that receives the sonar signal after the main bottom return. Fish and other objects close to the bottom that fall within the dead zone will probably not be visible in the sonar beam. Precision sonar beams, such as the Humminbird 20 beam, have a smaller dead zone than wider sonar beams. Decibel: A Decibel is the measurement for sound pressure level, or "intensity" of the sonar return. See dB Down Point. dB Down Point: The dB Down Point is the standard decibel level at which the sonar cone angle is measured, and is written as "@ -10 dB" or "@ -3 dB". Measurements at smaller down points (bigger negative numbers) indicate that the less intensive sonar signals are being used for the measurement. Display, FSTN: FSTN is an acronym for Film Super-Twist Nematic. FSTN is a monochrome display technology characterized by black, high-contrast pixels. All monochrome fixed mount Humminbird products use FSTN technology. DualBeam PLUS: DualBeam PLUS is a Humminbird sonar configuration that uses two sonar beams simultaneously, and combines the information from both beams into one view by overlapping the data on-screen, or shows each beam individually side by side, or permits each beam to be viewed individually full screen.

Hydrodynamic noise can be overcome by proper transducer installation. Many Humminbird products have a Noise Filter menu setting that allows the user to clear the screen of noise that is difficult to eliminate. Pixels: Pixels are the "picture elements", or small square blocks, that make up the image on the LCD. Measured as a vertical by horizontal number (i.e. 640V x 320H), this key specification typically indicates the quality of resolution. In fishfinders, the total resolution (vertical multiplied by horizontal) is often less important than the "Vertical Pixel" resolution. See Pixels, Vertical. Pixels, Vertical: Vertical Pixels are a number of vertical picture elements in a single column on an LCD display. A greater number of vertical pixels provide finer resolution of targets detected by sonar. Essentially, a vertical distance (the depth), when divided by a larger number, breaks that distance into smaller samples, each representing a smaller area and thus providing more detail. In fishfinders, vertical pixels are more critical than horizontal pixels because the horizontal axis of the display represents time, or history. Sonar information on the horizontal axis can vary greatly, depending on boat speed and the Chart Speed setting. A greater number of horizontal pixels show more sonar history that the boat has passed through. On many models, Humminbird provides the most vertical pixels to provide a better display resolution. See Chart Speed and Pixels. Power Output: Power output is the amount of sound energy emitted into the water by the sonar transmitter. Power output is measured using either RMS (Root Mean Square) or P-T-P (Peak-to-Peak) measurement systems. Either method is acceptable, but it is important, when comparing power outputs, to make sure that the same measurement system is being used for both outputs, because P-T-P numbers are 8 times higher than RMS numbers. Greater power output allows the sonar signal to penetrate through weeds and thermoclines, reach deeper depths and operate more effectively in noisy environments, such as when the boat is running at high speed. Pulse Width (Pulse Length): Pulse Width is the length of time that a sonar sound burst is transmitted into the water. Shorter pulse widths provide better target separation, but cannot travel to great depths. Longer pulse widths provide better depth penetration, but result in poorer target separation. Humminbird varies pulse width based on depth to optimize both target separation and depth performance. See Target Separation. 83

new range, and the old sonar information would continue to scroll off the screen at the old range. Transducer: The transducer is part of the sonar system, which mounts on the boat and is in contact with the water, that converts the electrical energy from the transmitter into sound energy, and that forms the sonar beam in turn. Internally, the transducer consists of one or more piezo electric disks that expand by very minute amounts to create the sound wave. This element also works in reverse, converting the returned sound energy back into an electrical signal that the receiver interprets. Transducers are available for many specific mounting applications for the boat, such as a transom mount, trolling motor mount, etc. Humminbird offers many sophisticated transducers, often with multiple piezo electric elements designed to form specifically-shaped sonar beams, providing the angler with superior tools for finding and catching fish. See Transmitter and SONAR. Transmitter: The transmitter and receiver are matched parts of the sonar system that send (transmit) and listen to (receive) the sonar signals, and work in conjunction with the transducer. Humminbird transmitters have an extremely fast cycling design that can send signals up to 60 times per second, as well as produce the varying levels of power output needed for different depths and conditions. Additionally, the transmitter has the capability to create very precise sonar pulses needed for a high degree of target separation. Humminbird receivers are extremely sensitive, but within a narrow "bandwidth" to discriminate against noise from external sources. Additionally, the receiver offers a wide "dynamic range" which provides the ability to receive very strong signals alternating with very weak signals, without the strong signal overwhelming the weak signal. See Transducer and Noise. TripLog: TripLog is a Humminbird feature that provides an on-screen counter for Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to activate the feature. TripLog appears on the Big Digits View, and can be reset to zero through the TripLog menu. TrueArch: TrueArch is a Humminbird feature that provides true fish arches, not artificial arches or symbols. Humminbird units are capable of producing fish arches due to the wide 60 sonar beam of DualBeam PLUS, an extremely sensitive sonar receiver. See Fish Arch. 87
