How Sonar Works
Sonar technology is based on sound waves. The 300 Series™ Fishfinder uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer.
Your 300 Series™ Fishfinder 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.
2 |
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:
•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 300 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.

the area under your boat, including the following items:
High Sonar Intensity Return
Bait Ball
Fish - The Fishfinder 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.
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 many colors moving across the display at the same depth.
Cursor - Available in Freeze Frame and can be positioned in the Sonar View to provide depth of a sonar return and bottomdepthbelow the cursor.

Understanding the Sonar Display
It is important to u nderstand the s ignificance of the d isplay. T he display d oes n ot s how a litera l 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 p articular segment of t ime w hen o bjects were detected, no t exactly where those objects a re in relation to other objects shown on the display.
The returned sonar echoes ar e displa yed on the screen. As a new ec ho 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 Wind ow™ 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 colors. Red indicates a strong return and blue indicates a weak return. The depth of the sonar return is indicated by t he ver tical placement of the return on the display depth scale.
The Wide R TS W indow™ indicates t he so nar i ntensity through the u se of a ba r graph. The length of the plotted r eturn indicates whether the return is weak or strong. The depth of the sonar return is in dicated by th e vertical p lacement of th e return o n the d isplay d epth
scale. The Wide RT |

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, cho ose Clear Mode. See Sonar Menu Tab: Switch Fire™ for more information.
Freeze Frame and Active Cursor
Freeze Frame & 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 m ove the cursor over a sonar return, and the depth of the sonar return will be displayed at the bottom ofthe screen in the cursor dialog box.
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, Split 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 b ottom can be d etermined 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.
