They're readily available at most marine dealers. SIGNAL INTERPRETATION Becauseyour Z-5000 is both extremelysensitiveand powerful, it can give you an accurate picture of the kind of bottom over whichyour boat is passing. A bottom of firm sand, gravel, shell, or hard clay returns a fairly wide signal. If the automatic sensitivity is turned off, and the signal narrows down, then it meansthat you have moved over a mud bottom becausemud absorbs the sound wave and returnsa weak signal. Turn up the sensitivity. Ifyou have the automatic senstivityturned on, watch the sensitivity bar As the boat passes over the mud bottom, the Z-5000 will automaticallyincreasethe sensitivityto maintaina good bottom signal. Thesensitivitybar will help you in determining if the bottom is soft or hard. If it increaseswhilein the same depth of water, then the boat has moved over a soft bottom. Of course, as the water depth increases or decreases, the sensitivitywill also change. Big rocks or stumpson a smooth bottom send back signals above the bottom level signal. The height of the signal depends on the target's height. If you watch as you approach a post or atree stump, it will be clearlyvisible as a short line extending above the bottom signal. Brush usually lies on the bottom and shows up as clumps rising above the bottomsignal. Brush signals look similar to large rocks, howevertheir signal is not as strong as rock. p Figure 3 PDF compression, OCR, web-optimization with CVISION's PdfCompressor 17 6 KEYBOARD BASICS CHART Thechartspeed is controlred bytheCHARTgroup of keys.

The angle betweenthe outside edges of the cone is called the cone angle. Eagle offers a choiceof transducers with either an 8 or 20 degree coneangle that will interchange with any of the 192 kHz sonar products. In otherwords, anyEagle sonar instrument can be used with any Eagle transducer of the same frequency with no loss of performance. However, the use of any other manufacturers'transducer will result in a loss SENSITIVITY LIGHT of performance. for operatingin shallow to medium water depths. The 20 degree cone angle allowsyouto seemore ofthe underwaterworld. In 15 feet of water the 20 degree cone covers an areaabout six feet across. The 8 degree transducer covers only about atwo foot circle. Generally, wide cone angle transducers (20 degrees)are ideally suited ZOOM The range can be expanded or zoomed" on the display byusing this key.

It automatically discriminatesbetweenthe valid bottom echoes and false echoes from fish, thermoclines, or other signals. The digital display will show only the bottom depth. When the Z-5000is firstturned on, the digital will flash "0" until it has "locked on" to the bottom signal. Once it has acquired the bottom depth, it will displaythe depth in the lower left of the display. - SEWSWVIIV 2 4 A /' I?' -4 4 6 AUTO t -- 0 SENSITIVITY LIGHT ____ tn k=ks -fl + + rzooM SENSITIVITY These keys control thegraph's sensitivity.
