69 SONAR OPERATION - General To view the sonar data, press the SONAR key at the bottom of the unit. A screen similar to the one below appears. This is a full-screen sonar display. The sonar data scrolls from right to left. The unit is in the auto- matic mode, shown at the top of the screen by the word “AUTO”. The automatic feature keeps the bot[...]

70 The SONAR key allows quick changes between sonar screens, each of which can be customized to your needs. AUTOMATIC The automatic feature is enabled when the unit is first turned on. This feature adjusts the sensitivity and range so the bottom signal shows in the bottom half of the display at all times. The word “AUTO” appears at the top of t[...]

71 currently in use. Continue pressing the arrow keys until you reach the desired level. If the unit is in the automatic mode, the sensitivity level can’t be in- creased or decreased past a certain point. An easy way to adjust the sen- sitivity in the manual mode is to first change the range to a depth that’s at least twice as deep as the curre[...]

72 To change the range, simply press the up arrow key to decrease it or the down arrow key to increase it. If the unit is in automatic, it may change the range immediately to keep the bottom on the screen. Another way to adjust the range is through the menus. Press the MENU key, then press the key adjacent to the “Sonar Con- trols ...” menu. A [...]

Changing the lower li[...]

74 For a full screen zoom view, simply press the SONAR key until the full screen zoom ap- pears. Since the unit is in the automatic mode, the GlobalMap 2000 keeps the bottom signal on the screen at all times, automatically adjust- ing the range. Manual If you’re in the manual mode, pressing the SONAR key gives you a 2X zoom, identical to the one [...]

75 ZOOM BAR After pressing the CLR key in the above procedure, the zoom bar disappears. If you wish to leave the zoom bar on the dis- play at all times, press the MENU key, then press the key next to the “Sonar Controls” label. Now press the key next to the “More” label until the “Zoom Bar” label appears. Press the key next to that labe[...]

76 The microcomputer is sophisti- cated, but it can be fooled. It can’t distinguish between fish and other suspended objects such as trotlines, turtles, sub- merged floats, air bubbles, etc. Individual tree limbs extending outwards are very hard for the unit to distinguish from fish. You may see fish symbols on the screen when there actually are [...]

77 FASTRACK The FasTrack feature converts all echoes to short horizontal lines on the right side of the display. The graph continues to operate normally. FasTrack looks similar to a flasher, mak- ing it useful for fishing at an- chor. Since the unit isn’t mov- ing, fish signals are long lines on a normal chart display. FasTrack converts the graph[...]

78 To adjust the Grayline level, press the MENU key, then press the key next to the “So- nar Controls” label. Now press the key adjacent to the “More” label until the “Grayline” menu appears as shown at right. Press the key next to the right arrow in the Grayline menu to increase it. Press the key adja- cent to the left arrow in the men[...]

79 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 ten feet, the alarm will sound a tone if the bottom sig- nal is less than ten feet. It will continue to sound until you mute it or when the bot[...]

80 Zone Alarm The zone alarm consists of a bar that appears on the right side of the display during the adjustment. You can also turn the zone alarm bar on continuously. Any echo that passes between the top and bottom of the zone alarm’s bar trips the zone alarm, even if the zone alarm bar is not displayed. To adjust the zone alarm, press the key[...]

81 ASP and Surface Clarity Control Noise, in electronic terms, is any undesired signal. Noise shows on the display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots or lines, obscuring target and bottom echoes. It’s caused by mechanical and electrical sources such as bilge pumps, engine ignit[...]

82 decrease it. The bar graph and percentage number shows the level of surface clarity in use. Press the CLR key when you’re finished. DIGITAL SONAR Each SAM actually has two sonar units in one box. One sonar is dedicated to the graph display, the other is the digital sonar display. The digital sonar is responsible for the digital depth display a[...]

83 feet, if the transducer is mounted three feet below the surface.) The difference be- tween the depth sounder’s reading (47 feet) and the ac- tual water depth (50 feet) is called the keel offset. In this example, to make the digital sonar read the correct depth, you would use a positive keel offset of three feet. Another time you may wish to ch[...]
