This typicallyhappens when you wishto see more detail, so an increase in sensitivity is indicated. The procedureto adjust it is the samewhetherthe unit is in the automatic or manual mode. To adjust the sensitivity, pressthe SENIS key. The sensitivity adjust menu appearson the left side of the screen. The switchfor the Graylineadjust menu is immediately beneath it.
GRAYLINP GRAYLINE® lets you distinguish between strong and weak echoes. It "paints" gray on targets that are stronger than a preset value. This allows you to tell the difference between a hard and soft bottom. For example, a soft, muddy or weedy bottom returns a weaker signal which is shown with a narrow or no gray line. A hard bottom returns a strongsignal whichcausesa wide gray line. If you havetwosignals of equal size, one with gray and the other without,then thetarget with gray is the strongersignal.

MENUS The UltraNav uses menus extensively to guide you throughthefunctions and featuresof theunit. The menu key accessesmany of these features, allowingyouto customize the unit to your particularneeds and waterconditions. Although you mayhaveto leave one menu and enter another to reach the desired function, all you haveto do is press the menu key to select the next menu. If you ever get lost in a menu, simplypress the key adjacentto the CLEAR label. There are eight sonar menus accessible with the menu key.
SONAR MENU - PAGE 1 FISH l.D. The Fish LD. feature identifies targetsthat meet certainconditionsas fish. The micro-computer analyses all echoes and eliminatessurface clutter, thermoclines,and other signals that are undesirable. In most instances, remaining targets are fish. The Fish LU. feature displays symbols on thescreen in placeofthe actual fish echoes. There are fourfish symbolsizes:tiny, small, medium, and large. These are used to designatetherelative size between targets.

Anytargets the microcomputerdetermines are fish will be displayedas fish symbols. Remember, the Fish ID. featurecannotbe used when the UltraNav is in the manual mode. If you turn the Fish l.D.
SONAR MENU - PAGE 2 FASTRAK This feature converts all echoes to short horizontal lines on thedisplay's far right side. The graph continues to operate normally. FASTRAKgives you a rapid update of conditions directly under the boat. This makes it useful for ice fishing, or when you're fishing at anchor.

• TRANSDUCERCONE ANGLES The sound waves from the transducer spread out intothe water in a cone shaped beam. Thislooks much like the beam from a flashlight. The angle betweentheoutsideedges of the cone is the cone angle. Eagleoffers a choice of transducers with either an 8 or 20 degree cone angle. The transducer supplied with the Ultra has a 20 degree cone angle. Typically, wide cone angle transducers (20 degrees) are ideal for operating in shallow to mediumwaterdepths.
Both 8 degree and 20 degree transducers give accurate bottom readings, even though the bottom signal is much wider on the 20 degree model. This is becauseyou are seeing more of the bottom. Remember, the shallowedge of the signal showsyou thetrue depth. The rest of the signal tells you whetheryou are over rocks, mud, etc. SIGNAL INTERPRETATION Your UtraNavgives an accuratepicture of the bottomthat your boat is passing. A bottom of firm sand, gravel, shell, or hard clay returns a fairly wide signal.
FISH ARCHES Fish arches are created when the cone of sound passes over a fish. The distance to a fish when the cone first strikes it is shown as "A" below. When the center of the cone strikes the fish, the distance is shorter as shown "B". As the cone leaves the fish, the distance increasesagain as shown in "C". BOATS DIRECTION OF TRAVEL CENTRAL PACIFIC LORAN-C CHAIN CR14900 REGIONAL MANAGERCOMMANOER. PACIFIC AREA.
Very small fish probablywill not arch at all. Mediumsizedfish will show a partial arch, or a shape similar to an arch if they're in deep water. Largefish will arch, but turn thesensitivity up in deeperwaterto see the arch. Because of water conditions, such as heavy surface clutter, thermoclines, etc., the sensitivity sometimes cannot be increased enoughto getfish arches. 3. If you're using the loran on land, keep away from trees, buildings, and (most important)power lines.

SURVEYINGA LAKE The most successful anglers on any body of water are thosewho fish it day after day and year afteryear. Eventually, they learn thehotspots that produce fish consistently. They discover through experience where, and at what depth,they can expect to find thefish they want at any season. And they realize that these productive areas change throughout the year dependingon water level, temperature, food, and other factors.
