The system includes a transducer and a display unit, connected by a cable. These sounds strike fish, the bottom, or other objects in the water, and return as echoes. The FishFinder L470 can handle many different jobs: · detect the presence of fish below the boat · trigger an alarm when fish are found · measure the depth of the water · set alarms for minimum and maximum depth · show the shape of the bottom · determine whether the seabed is hard or soft · measure the speed of the boat and the distance traveled · show the water temperature We are sure you will find the FishFinder L470 to be one of the most useful devices on your boat. Raymarine PWR FishFinder L470 Display Unit SETUP CLEAR ZOOM A-SCP BOT LOCK L470 Optional Thru Hull Transducer Transducer mounted in quick release transom bracket Fig. [. . . ] You must also select the area or "window" of the water you want to zoom. Zoom area When you turn on the zoom feature, it can only enlarge a part of the FishFinder Page. As we said, the right side of the "split" display shows the normal FishFinder Page. The vertical line at the right edge of this display shows the area or "window" of the water being enlarged. When the FishFinder is set for Auto Zoom, it will choose the zoom area automatically. The unit always chooses an area of the water which includes the bottom. The unit then moves this area up or down to keep the bottom in the picture. Once you are back to the zoom display, you can move the zoom area up or down (using the and V arrows of the Page Control Pad) to select the area you want to be enlarged. If you want to exit from the Zoom Mode, press the Zoom button again while the Zoom image is visible. For a moment the display will say, "Exiting Zoom Mode, " then the unit will return to the FishFinder Page. < Operating Instructions 51 A-Scope (Bottom Coverage) Mode Normal display A-Scope display A-Scope image (real time image) Fig. 3-14 A-Scope Mode (half screen) Fish indication Bottom coverage On the FishFinder Page the bottom graph is "drawn" after the FishFinder receives several echoes. The A-scope Mode shows raw sonar data directly from the transducer beam. This gives you a "real time" image of fish and bottom structure directly below the transducer. (The A-Scope Mode is sometimes called an "In-Line Flasher. ") This function is very useful in showing the strength of the echo returned from a fish. You can reach the A-Scope Mode at any time by pressing the A-Scope button. The left section of the A-Scope Mode shows a section of the normal FishFinder Page. A-Scope image The normal FishFinder Page with the White Line feature enabled (see Fig. 3-4) allows you to tell the difference between two levels of echo strength. Weak targets are shown in black, while strong targets are shown in a gray checkered pattern. In the A-Scope Mode, stronger echoes 52 Operating Instructions create wider lines. Unlike the scrolling FishFinder Page, the A-Scope does not show a history of scans; instead, it is a "real-time" display. The shape of the A-Scope display shows the result as the sonar beam spreads as it penetrates deeper into the water. [. . . ] Sometimes a thermocline can reflect sonar waves and present a false display. Transducer: A device which sends and receives high frequency sound waves through the water. Transom: The rear-most part of the boat's hull, often a flat panel. This feature helps to show the difference between weak returns (including fish near the bottom) and strong returns (including the bottom itself). [. . . ]
