FISHTRACKTM The FishTrack feature shows thedepth of afish symbol when it appears on thedisplay. This lets you accurately gaugethedepth of targets.This feature is available only whenthe Fish ID featureis on. The Fish l.D. feature identifies targets that meet certain conditions as fish. The micro-computer analyses all echoes and eliminates surface clutter, thermoclines, and othersignals that are undesirable. In most instances, remaining targetsare fish. The Fish l.D. feature displays symbols on the screen in placeofthe actual fish echoes. There are fourfishsymbolsizes: tiny, small, medium, and large. These are used to designate the relative size between targets. In otherwords, it displays a small fish symbolwhen it thinks atargetis a small fish, a mediumfish symbol on a largertarget, etc. To turn the FishTrack feature on, press the menu key, then press the key adjacent to the "Fish-ID On Off FishTrack" label untiltheblackboxsurrounds the "FishTrack" label.

This allows youto tell the difference between a hard and soft bottom. Forexample, a soft, muddy or weedy boftom returns a weakersignal whichisshown with a narrowor no gray line. A hard bottom returns a strong signal which causesawide gray line. If you have two signals of equal size, onewith gray and the other without, then the target with gray is the stronger signal. This helps distinguish weeds fromtrees on the bottom, orfish fromstructure. GRAYLINE isadjustable. SinceGRAYLINE showsthedifferencebetween strong and weaksignals, adjusting the sensitivity may require a different 22 menu.

These markings are caused by wave action, boat wakes, temperature inversion, and other natural causes. The SurfaceClarity Control (SCC) reduces or eliminatessurface clutter signals from the display. SCC varies the sensitivity of the receiver, decreasing it near the surface and gradually increasing it as the depth increases. The maximum depth that SCCwill affectis 75%of the selected depth range. For example, on a 0-60 foot range with maximum SCC, 17 PDF compression, OCR, web-optimization with CVISION's PdfCompressor 30 surface clutterwill be reduced downto 45 feet.

ASP (Advanced Signal Processing) The ASP feature is a noise rejection system built into the Ultra Ill that constantly evaluates the effects of boat speed, water conditions, and interference. This automatic feature gives you the best display possible undermostconditions. 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 overtheface of thetransducer, evenvibration fromthe engine. In all cases, noisecan produce unwanted marks on the display. The ASPfeaturehastwo levels - Normal and High. Ifyou have high noise levels,try usingthe"High"ASPsetting. However, ifyouare having trouble with noise, we suggest that youtake steps to findthe interference source and fix it, ratherthan continually usingthe unitwith thehigh ASPsetting. However,thereare timeswhenyoumaywantto turnthe ASPfeature off. Thisallowsyoutoview all incoming echoes before theyare processed by the ASP feature.

SIGNAL INTERPRETATION Your Ultra Ill gives an accurate picture of the bottom that your boat is passing. A bottomof firm sand, gravel, shell, or hard clay returns a fairly wide signal. Ifthe automatic mode isoffand thesignal narrows down,then it means that youhave moved overa mud bottom. Mud absorbsthe sound wave and returns a weak signal. Turn up the sensitivity to see a better bottomsignal. To switch between the split screen zoom and full screen zoom, press the key adjacent tothe "SPLIT/FULL" label. The screen instantly splits into two sections. All targetson the left are shown at four times the size of the ones on the right. If you switch to the 2X zoom mode, echoes on the leftside of the screen are shown attwicethe size as the ones on the right. The echoes that scroll across the screen are the exactsameechoes on both sides ofthescreen.

(Seethetop of the nextpage.) Eagle offers a choice of transducers with either an 8 or 20 degree cone angle. The transducer supplied with the Ultra Ill has a 20 degree cone angle. Typically, wide coneangle transducers (20 degrees) are ideal for operating in shallowto medium waterdepths. The 20 degreecone angle allowsyouto see more of the underwaterworld. In 15 feet ofwaterthe 20 degree cone covers an areaabout six feet across. The 8 degree transducer coversonly about a two foot circle. 32 When you pressthe zoom key while the unit is in the manual mode, the screen shown below appears. All of the menus on this screen work identically as described above. However, one additional menu item is shown when the unitis in the manual mode:"ADJUST". To adjust the zoom, press the key adjacent to the "ADJUST" label. A screen similarto the one below appears. A zoom bar and adjustarrows appearon the screen.

A low sensitivity level excludes much of the bottom information, fish signals, and othertargetinformation. High sensitivity levelsenables youtoseethis detail, butitcan also clutterthescreenwithmany undesired signals. Typically, the best sensitivity level shows a good solid bottom signal with Grayline and some surface clutter. When the Ultra Ill isin the Automatic mode,the sensitivity isautomatically adjusted tb keep a solid bottom signal displayed, plus a little more. This gives it the capability to show fish and other detail. However, situationsoccurwhere it becomes necessary to increase or decrease sensitivity. Thistypically happens whenyouwishtoseemore the so an increase in sensitivity is indicated. The procedure to adjustit detail, is the samewhetherthe unit is in the automatic or manual mode. FISH ARCHES Fish arches are created when the cone of sound passesover a fish. The distance to a fish whenthe conefirststrikes it is shown as "A" on the next page. When the centerofthe conestrikes thefish, the distance is shorter as shown "B". Asthe cone leaves thefish, the distance increases againas shown in "C". Very small fish probablywill not arch atall. Medium sizedfish will showa partial arch, orashapesimilartoan arch ifthey'rein deep water.Largefish will arch, but turn the sensitivity up in deeper water to see the arch. Because ofwaterconditions, suchas heavy surface clutter, thermoclines, etc.,thesensitivity sometimes cannot beincreased enoughto get arches. Oneofthebestwaysto get fish arches is to expand or "zoom" a segment ofthewater.Forexample,from 60feet. Thesmallerthesegment, the 45to betterthescreen resolution will be.The easiest wayto do this ontheUltra Ill is with theZoomfeature. This feature expands the echoes, making it easierto seedetail. Forthe bestresults, turn the sensitivity up as high as to possible withoutgetting too much noiseon the screen. In medium deep water, this method should workto display fish arches. To adjustthe sensitivity, press the SENS key. Thesensitivity adjustmenu appearsatthebottom ofthe screen. The sensitivity menu hasleftand right arrows, plus a horizontal bargraph. The graph gives a visual indi _______________________________ cation of the sensitivity level. 52 1 FTth The number above the INC arrowalso showsthepercentage of sensitivity in use. 0 41 Toincreasethesensitivitylevel, press the right arrow key. As you press the key, the menu's bar graph will grow wider and the percentage will increase in value. You can also see the differenceon the chart record as it scrolls. When the sensitivity is at the desired level, release the key. To decreasethe sensitivity level, press thekeyadjacentto the leftarrow. The bar graph and percentagewill decrease. When the sensitivity is at the desired level, release the key. When you reach either the maximum or minimum limit, a tone sounds. To turn the menus off, press the key adjacent to the CLEAR key at the bottom left side of the unit or wait a few seconds and the menus will disappear. 13 .11 ·4IO 34 IIIIb!

WATERTEMPERATURE ANDTHERMOCLINES Watertemperaturehas an important-if not controlling-influence upon the activitiesof all fish. Fish are cold blooded and their bodies are alwaysthe temperature of the surrounding water. During the winter, colder water slows down their metabolism. At this time, they need about a fourth as much food as they consume in the summer. Mostfishdon't spawn unless thewatertemperature iswithinrather narrow limits. A surface temperature meter helps identify the desired surface water spawning temperatures for various species. Trout can'tsurvivein streamsthat get too warm. Bass and otherfish eventuallydie out when stockedin lakes that remain toocold during the summer. While somefish have awidertemperature tolerance than others, eachhasa certain range withinwhich ittriesto stay.Schooling fish suspended overdeepwater lie at the level that provides this temperature. We assume theyarethemost comfortable here. VIEWING WINDOWS To seeall ofthe available windows, press the WINDOWS key, thenpress theMENU key. Some:· I Nowpressthe key adjacent to the "MAIN MENU" label.

(Seethepicture on the nextpage.) Layers ofdifferenttemperatures form, and the junctionof a warm and cool layer of wateris called athermocline. The depth and thickness of the thermocline can vary with the season or time of day. In deep lakes there may be two or moreat different depths. Thermoclines are important to fishermen because they are areas where fish are active. Many times baitfish will be above the thermoclinewhile largergame fish will suspend in or justbelow it. The Ultra III can detect this invisible layerin the water, but the sensitivity will probablyhaveto be turned up to see it. SURVEYING OPERATION AUTOMATIC Whenthe Ultra III isfirstturned on, the Automatic featureisenabled. This is indicatedby the word "AUTO"at the top of the screen.
