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 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. (See Section 4. ) Once you are back to the zoom display, you can move the zoom area up or down (using the and arrows on the Page control pad) to enlarge any selected "window. " To move to the next display, press the > arrow on the Page control pad. < < 38 Operating Instructions A-Scope (Bottom Coverage) Page Press Normal display A-Scope display A-Scope image (real time image) Fish indication Bottom coverage Fig. 3-8 A-Scope Page On the FishFinder display the bottom graph is "drawn" after the FishFinder receives several echoes. The A-scope displays raw sonar data directly from the transducer beam. This gives you a "real time" image of fish and bottom structure directly below the transducer. This function is very useful in showing the strength of the echo returned from a fish. Stronger fish echoes on the A-scope display will appear wider; weaker echoes appear as narrow bands closer to the horizontal center of the A-scope image. Operating Instructions 39 The left section of the A-Scope display shows a section of the normal FishFinder display. A-Scope image This shows the beam of sound waves extending down from the boat, and spreading as it moves through the water. Any fish or objects which are positioned under the boat will appear on the display. This is a "real time" display, so you can see the fish symbols moving as the fish swim under the boat. Bottom coverage This shows the diameter of the beam of sound waves where it meets the bottom. This dimension will be shown using the same units as the rest of the display ­ feet (FT), fathoms (FA), or meters (M). If the unit is set at 200kHz single frequency, the bottom coverage display will reflect the narrow (16°) beam of the 200kHz frequency setting. All other frequency selections (200kHz dual, 50kHz dual, and 50kHz single) use the wider (65°) beam for the bottom coverage display. To move to the next page, press the > arrow on the Page control pad. 40 Operating Instructions Digital Page Press Depth Fig. 3-9 Alarms Digital Page The Digital page presents the depth in large numbers on the display. This display is useful when you are traveling, but not looking for fish or checking the appearance of the bottom. Notice that the alarm indications still appear at the bottom of the display. To move to the next display, press the > arrow on the Page control pad. Operating Instructions 41 Sidelooker Page Press This feature will only work if an optional Sidelooker transducer has been installed, and if the Sidelooker feature has been turned on in the System Setup Menu. [. . . ] Zoom: A way of magnifying or enlarging part of the display to give a better view of a section of the water. 72 Glossary Limited Warranty Certificate Raymarine warrants each new Light Marine/Dealer Distributor Product to be of good materials and workmanship, and will repair or exchange any parts proven to be defective in material and workmanship under normal use for a period of 2 years/24 months from date of sale to end user, except as provided below.
