How Sonar Works TM Sonar technology is based on sound waves. The 100 Series Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. TM Your 100 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
Resumen del contenido incluido en la página 9
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 measu

Single Beam Sonar Your 100 Series™ Fishing System uses a 200 kHz Single Beam sonar system with a 20° area of coverage. The 20° beam is focused on the bottom, to show you structure, weeds and cover. How GPS and Cartography Work TM Your 100 Series Fishing System also supports GPS and chartplotting, and 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
Resumen del contenido incluido en la página 11
GPS uses a constellation of 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 t

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 TM instance, by switching between "Inverse" and "Structure ID®" from the X-Press menu, it is possible to quickly a

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

Understanding Sonar History It is important to understand the significance of TM the 100 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 objec

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 a

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 o
