Then, you can turn on Fish I.D. and the audible fish alarm. When that lunker swims under your boat, you'll hear it! Fish I.D. can also be useful when you want to screen out some of the sonar detail gathered by your unit. For example, in one case fishermen in San Francisco Bay saw clouds of clutter in the water but no fish arches. When a down rigger was pulled up, it brought up several small jellyfish. The fishermen switched their sonar to Fish I.D., which screened out the schools of jellyfish and clearly showed the game fish there as fish symbols. Other Free Training Aids The sonar options section discusses Fish I.D., fish alarms and other features in greater detail. If you or a friend has Internet access, you can also learn more about interpreting what you see on your sonar screen. Visit our web site, WWW.EAGLESONAR.COM. Be sure to check out the free Sonar Tutorial, which includes animated illustrations and more pictures of actual sonar returns, all described in detail. There's even a 43 "printer friendly" version of the tutorial available on our web site…it makes a great supplement to this operation manual! "printer friendly" version of the tutorial available on our web site…it makes a great supplement to this operation manual! This PC application simulates the actual sonar unit on your computer. You can run it from your computer keyboard or use your mouse to press the virtual keys. Easy download and installation instructions are available on our web site. Free training emulator is available for your unit on our web site. The emulator works exactly like your real sonar unit. Using the Sonar Simulator feature, it allows you to play the demo sonar log, and practice changing the various settings available in your Eagle sonar unit! 44 Section 4: Sonar Options & Other Features Section 4: Sonar Options & Other Features ASP. (Advanced Signal Processing) The ASP. feature is a noise rejection system built into the sonar unit that constantly evaluates the effects of boat speed, water conditions and interference. This automatic feature gives you the best display possible under most conditions. The ASP feature is an effective tool in combating noise. In sonar terms, noise is any undesired signal. It is caused by electrical and mechanical sources such as bilge pumps, engine ignition systems and wiring, air bubbles passing over the face of the transducer, even vibration from the engine. In all cases, noise can produce unwanted marks on the display. The ASP feature has four settings — Off, Low, Medium and High. If you have high noise levels, try using the "High" ASP setting. However, if you are having trouble with noise, we suggest that you take steps to find the interference source and fix it, rather than continually using the unit with the high ASP setting. There are times when you may want to turn the ASP feature off. This allows you to view all incoming echoes before they are processed by the ASP feature. At left, Sonar Menu with Sonar Features selected. In the Sonar Features menu, Noise Rejection is selected with ASP in the default low setting (center, dual-frequency menu; at right, single-frequency menu). 45 To change the ASP level: To change the ASP level: From the Sonar Page, press MENU|v to SONAR FEATURES|ENT. 2. Press >v or v to NOISE REJECTION|ENT. 3. Press v or ^ to select a setting, then press ENT. 4. To return to the previous page, press EXIT|EXIT. Alarms This unit has three different types of sonar alarms. The first is the Fish Alarm. It sounds when the Fish I.D.. feature determines that an echo is a fish. Another alarm is the Zone Alarm, which consists of a bar on the side of the screen. Any echo on the chart that appears inside this bar triggers this alarm. The last alarm is the Depth Alarm, which has both a Shallow and a Deep setting. Only the bottom signal will trigger this alarm. This is useful as an anchor watch, a shallow water alert or for navigation. Depth Alarms The depth alarms sound a tone when the bottom signal goes shallower than the shallow alarm's setting or deeper than the deep alarm's setting. For example, if you set the shallow alarm to 10 feet, the alarm will sound a tone if the bottom signal is less than 10 feet. It will continue to sound until the bottom goes deeper than 10 feet. The deep alarm works just the opposite. It sounds a warning tone if the bottom depth goes deeper than the alarm's setting. Both depth alarms work only off the digital bottom depth signals. No other targets will trip these alarms. These alarms can be used at the same time or individually. 46 To adjust and turn on the shallow alarm: To adjust and turn on the shallow alarm: Press ALARM. 2. Press > to SHALLOW ALARM DEPTH|ENT. 3. Press ^ or v to change the first number, then press > to move the cursor to the next number and repeat until the depth is correct, then press ENT. 4. Press < to SHALLOW ALARM ENABLED|ENT|EXIT. 5. To turn off the alarm, press ALARM|ENT|EXIT. To switch to a different depth setting, open th...
