iv Notes.
1 Introduction Thank you for buying an Eagle sonar! Your unit is a high-quality so- nar designed for both professional and novice fishermen. All Eagle so- nars have an automatic mode that finds and displays the bottom, fish, underwater structure and more – right out of the box.
2 Display: ............................ High-contr ast Film SuperTwist LCD. Diago- nal viewing area: 3.5" (8.9 cm). Resolution: ...................... 240 pi xels (vert.) x 160 pixels (horiz.) resolu- tion; 38,400 total pixels Backlighting: .....
3 Auto bottom track: ........ Yes. Zoom bottom track: ....... Yes. Split-screen zoom: ......... Ye s. Surface water temp: ..... Yes, built into transducer. Optional external temperature sensor or combo speed/temp sensor available. Speed/distance log: .
4 The transmitter emits an electrical impulse, which the transducer con- verts into a sound wave and sends in to the water. (The sound frequency can't be heard by humans or fish.) The sound wave strikes an object (fish, structure, bottom) and bounces back to the transducer, which converts the sound back into an electrical signal.
5 Transducer Installation Preparations The following shows the recommended sequence for installing the transducer: CAUTION: You should read over this entire installation section before drill- ing any holes in your vehicle or vessel! 1.
6 trolling motor mount uses a one-piece plastic bracket with an adjust- able strap. These are all "kick-up" mounting bracke ts. They help prevent damage if the transducer strikes an object while the boat is moving. If the trans- ducer does "kick-up," the bracket can easily be pushed back into place without tools.
7 Single-frequency trolling motor ins tallations Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic cable ties. Shoot-through hull installations Tools: these will vary depending on yo ur hull's composition. Consult your boat dealer or manufacturer.
8 Left, vee pad hull; right, vee hull. A pod style transducer is shown here, but the principle is the sa me for Skimmers inside a hull. 4. If the transducer is mounted on the transom, make sure it doesn't interfere with the trailer or hauling of the boat.
9 How low should you go? For most situations, you should in stall your Skimmer transducer so that its centerline is level with th e bottom of the boat hull. This will usually give you the best combination of smooth water flow and protec- tion from bangs and bumps.
10 tion (often called simply "thru-hull"). In that case, a hole is cut in the hull and a specially designed transducer is mounted through the hull with a threaded shaft and nut.
11 the metal bracket. This position sets the transducer's coarse angle ad- justment for a 14 ° transom. Most outboard and stern-drive transoms have a 14 ° angle. Align plastic ratchets in bracket. 2. Aligning the transducer on the transom. Slide the transducer between the two ratchets.
12 Insert bolt and check transducer position on transom. 3. Assembling the transducer. Once you determine the correct posi- tion for the ratchets, assemble the transducer as shown in the following figure. Don't tighten the lock nut at this time. Assemble transducer and bracket.
13 4. Drilling mounting holes. Hold the transducer and bracket assem- bly against the transom. The transducer should be roughly parallel to the ground. The transducer's centerlin e should be in line with the bot- tom of the hull. Don't let the bracket extend below the hull! Mark the center of each slot for the mounting screw pilot holes.
14 Route cable over bolt and through bracket. Side view shown at left and seen from above at right. Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures.
15 Align transducer centerline with hull bottom and attach to transom. 6. Route the transducer cable through or over the transom to the sonar unit. Make sure to leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wir- ing on the boat.
16 located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline seal- ant used for the mounting screws. 7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the trans- ducer bracket down.
17 3. Route the transducer cable alon gside the trolling motor shaft. Use plastic ties (not included) to attach the transducer cable to the trolling motor shaft. Make sure there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the transducer is ready for use.
18 Transducer angles and their effects on fish arches. If the arch slopes up – but not back down – then the front of the trans- ducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of th e transducer is angled too far down and needs to be raised.
19 NOTE: Periodically wash the transducer's face with soap and water to re- move any oil film. Oil and dirt on the face will reduce the sensitiv- ity or may even prevent operation.
20 For example, some (but not all) manuf acturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layer of fiberglass. Removing the inner layer of fibergla ss and the balsa wood core exposes the outer layer of fiberglass.
21 (more rocky) the bottom, the easier it will be to get a second bottom sig- nal.) Don't touch the controls once they've been set. Example of a second bottom signal. Unit is in 30 feet of water, with range set at 80 feet and sensitivity set at 87 percent.
22 hull. This is especially true if you have to turn sensitivity all the way up to get a dece nt bottom signal. 4. Most people can get good results by following steps 1 through 3, so this step is optional .
23 Epoxy transducer to hull. WARNING: Use only the epoxy available from LEI. It has been for- mulated to work with these installation procedures. Other epoxy types may be too thin or may not cure to the right consistency for optimum transducer perform- ance.
24 air pockets in the epoxy layer! Then, apply the remaining epoxy to the sanded area on the hull. 3. Press the transducer into the epo xy, twisting and turning it to force any air bubbles out from under the transducer face. Stop pressing when you bottom out on the hull.
25 Speed/Temperature Sensors The FishEasy 240 family can accept as many as two temperature sensors, which can be used to monitor the temperature of surface water, a live well or some other location. These units can accept an optional speed sensor for showing speed and distance traveled.
26 See the following charts for sample sensor combinations and cable con- nections. Sonar unit with external combination speed and temperature sensor. Primary temp sensor is built into transducer.
27 Sonar unit with secondary external temperature sensor. Primary temp sensor is built into transducer. TS-2U temperature senso r Temperature sensor built into transducer Sonar unit rear view 12-volt .
28 Sonar unit with external speed sensor. Temp sensor is built into transducer. Speed Sensor Installation If you wish to purchase an optional sensor for your unit, refer to the accessory ordering information insi de the back cover of this manual. The following instructions describe how to install the speed sensor.
29 First find a location on the boat's transom where the water flow is smoothest. Don't mount the sensor behind strakes or ribs. These will disturb the water flow to the speed sensor. Make sure the sensor will remain in the water when the boat is on plane.
30 Speed sensor mounting configuration: side view (left) and rear view (right.) If the base of the transom has a radius, fill the gap between the tran- som and the sensor with the caulking compound. This will help ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit.
31 interference, attach the power cable di rectly to the battery. If the cable is not long enough, splice #18 gauge wire onto it. CAUTION: When using the unit in a saltwater environment, we strongly rec- ommend that you shut off the power supply to the power cable when the unit is not in use.
32 If possible, keep the power cable away from other boat wiring, espe- cially the engine's wires. This will provide the best isolation from elec- trical noise. The power cable has tw o wires, red and black. Red is the positive lead, black is negative or ground.
33 Mount the unit in any convenient loca tion, provided there is clearance when it’s tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power/transducer cable. (See the following drawings, which show the dimensions of a gimbal-mounted FishEasy 240 sonar unit.
34 Front view (left) and side view (right) showing dimensions of the FishEasy 240 when mounted on quick release bracket. After drilling the hole, pass the connectors up through the hole from und er t he d as h. If you wish, you can fill in the hole around the cable with a good marine caulking compound.
35 Align the bracket over the cable hole with the cable slots facing away from you and fit the cable through one of the slots. Fasten the bracket to the dash using the three screw holes. FishEasy 240 quick release mounting bracket. Slots in the base allow routing the cable from beneath the mount.
36 Mount the sonar: slide the unit onto the bracket from above. Adjust viewing angle: use one hand to press and release the spring- loaded ratchets while you move the unit with the other hand.
37 Portable Sonar Installation Like many Eagle products, the FishEasy 240 sonar is capable of port- able operation. It uses the optional PPP-12 po rtable power pack.
38 PPP-12 Portable Power Pack with Fi shEasy 240 stowed for transport. Turn the sonar unit on. If it doesn' t work, make sure the battery termi- nals are making good contact against the battery contacts. Also check the wiring connections on the battery adapter.
39 Portable Transducer Assembly Recommended tools for installation include a slotted screw driver and two adjustable wrenches. Assemble the transducer and bracket as shown in the following figure. Attach the transducer to the bracket with the supplied hardware.
40 allow the bracket to extend below the hull, because water pressure against it can cause the suction cup to come off at speed. Moisten the cup, then press it onto the hull as firm ly as possible. Tie the nylon cord to the boat and route the transducer cable to the sonar unit.
41 Operation Keyboard Basics The unit sounds a tone when you pre ss any key. This tells you the unit has accepted a command. Numbers in the figure correspond to key ex- planations below: Eagle FishEasy 240 Sonar, showing screen and keyboard. 1. PWR/CLEAR (power and clear) This key appears in the manual text simply as PWR .
42 3. MENU DOWN (menu down) These keys appears in the manual text as MENU UP or MENU DOWN . Most of the time, the instructions require you to press either menu key, so the text simply uses the word MENU . Usually, when we say MENU , you can simply press the MENU UP key for consistency.
43 This screen shows a typical menu, the Scroll Speed menu. Display – Opening Screen The lights flash for about 10 seconds when the unit is turned on. The backlight menu first appears on the screen. To turn the lights on, press UP A RROW . If you don’t press a key, the menu will disappear after a few seconds.
44 Opening screen, Full Chart page, or mode. Chart Scroll (stopping and starting) In normal operation, the sonar chart will scroll from right to left across the screen. You can stop the chart fr om scrolling across the screen. This is useful when you want to "freeze" the picture to study it more closely.
45 Chart menu. Chart is running or scrolling normally at left. Chart is stopped at right, and "Stopped" warning message appears. Screen Display Modes or Pages The FishEasy 240 has three screen display modes, or "Pages:" Full Chart page, Split Chart page and Large Digital page.
46 page. (The screen changes as you move through the menu.) When the page you want is selected, press PWR to clear the menu. Full Chart This shows all echoes scrolling across the full screen. This is the default page. The bottom signal scrolls acro ss the screen from right to left.
47 Split Chart page with normal view at right; zoomed view at left. Lrg Digital (Large Digital) The Large Digital page shows all information in big numbers. The digi- tal depth display is at the top of this screen, followed by the tempera- ture, speed, and distance readings.
48 Range When turned on for the first time, the unit automatically adjusts the depth range according to water cond itions. It always keeps the bottom displayed in the lower portion of the screen. You can over-ride the automatic range control and manually select a range.
49 Zoom screen, showing Zoom menu and the 2X zoom indicator at the top right of the screen. To zoom the display, first press the MENU key until the Z OOM menu ap- pears. Use the arrow keys to select either 2X or 4X zoom, then press PWR to clear the menu.
50 In 34 feet of water, with the Ra nge set manually at 60 feet, the unit shows the entire water column in Fig. 1. To get a closer look, turn around and follow your wake to troll over the structure again.
51 Sensitivity Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the se nsitivity, a little at a time. There are situations when too much clutte r appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish ech- oes, if fish are present.
52 These figures show results of different sensitivity levels on the same location. Fig. 1: Sensitivity at 87 percent, determined by Auto Sensitiv- ity. Typical of full auto mode. Fig. 2: Sensitivity set at 50 percent. Fig. 3: Sensitivity set at 20 percent.
53 Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting a car's speed with the accelerator pedal while cruise control is on. You can tell the car to run faster, but when you let off the gas the cruise control automatically keeps you from running slower than the minimum speed setting.
54 To adjust sensitivity: Press MENU until the S ENSITIVITY A DJUSTM ENT menu appears. Press UP A RROW to increase the sensitivity, DOWN A RROW to decrease it. When it's set at the desired level, press PWR to clear the menu. The sensitivity percentage in use sh ows in this menu.
55 To change the Grayline level, press MENU until the G RA YLINE menu ap- pears. Press UP ARROW to increase the level or press DOWN A RROW to de- crease it. The percentage of Grayline in use shows in this menu. Echoes scrolling onto the screen will also show the effects of the Grayline change.
56 displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target and so forth. At left, underwater scene in normal fish arch mode. Right, Fish I.D. menu with the feature turned on. Fish I.D. is an easier way for a sona r novice to recognize a fishy signal return when he sees it.
57 out of reading the screen. Remember: Fish I.D. is one of the many tools we provide so you can analyze your sonar returns for maximum fish finding information. This and other features can help you successfully "see" beneath the boat under varied water and fishing conditions.
58 Fish ID menu and symbol with FishTr ack on. The fish is 44 feet deep. FishReveal When displaying actual sonar returns, the FishReveal feature helps show fish targets hidden by surface clutter, thermoclines, weed beds and other cover with 10 le vels of gray tones.
59 At left FishReveal menu screen. The feature is off and screen is in normal mode. Right, Fish Reveal is on, in standard mode. There are two FishReveal modes: standard and inverted. In standard mode, the weakest echoes are white an d the strongest echoes are black.
60 To turn FishReveal on, press MENU DOWN until C HART S ETUP appears, then press UP ARROW . Press MENU DOWN until C HART M ODE appears. Press DOWN ARROW to select the desired FishReveal mode. Press PWR to clear the menu. To return to no rmal operation, repeat the above steps, but select N ORMAL before clearing the menu.
61 At right, Scroll Speed menu at default 60 percent setting. At left, Scroll Speed menu, with unit set to HyperScroll mode. If you are running fast, try a Hype rScroll setting of 80 to 100 percent. When using HyperScroll, you may also need to manually decrease the sensitivity for best performance.
62 ASP is an effective tool in combating noise. In sonar terms, noise is any undesired signal. It is caused by el ectrical and mechanical sources such as bilge pumps, engine ignition systems and wiring, air bubbles pass- ing over the face of the transducer, even vibration from the engine.
63 Alarms The sonar unit has two different ty pes of alarms, fish and depth. Fish Alarm The Fish Alarm sounds a tone when a fish symbol appears on the screen. The default setting is on, but the Fish I.D. feature must be turned on for fish alarms to work.
64 Shallow Alarm To set the shallow alarm depth, press MENU DOWN repeatedly until S HALLOW A LARM appears. Shallow Alarm menu. Press UP ARROW to increase the shallow alarm's depth setting or press DOWN A RROW to decrease it. The number in the shallow alarm’s menu box shows the current shallow alarm setting.
65 shows the current deep alarm setting. When the number reaches the desired setting, press PWR to clear the menu. When the bottom depth goes deeper than the alarm’s setti ng, an alarm tone sounds and a mes- sage box appears on the screen. Deep Alarm menu.
66 System Setup menu. Display Adjustments Backlights The display is backlit for night use. To turn the backlight on or off, press MENU repeatedly until the B ACK L IGHT menu appears. Press UP A RROW to turn the light on or the DOWN ARROW to turn it off.
67 Display Contrast The unit’s display contrast is adjustable to suit different lighting condi- tions. This will help you see the screen from different angles or at vari- ous times of the day.
68 Depth menu controls the unit of measure used to show depth. Temperature Units of Measure This unit can show the temperature ( if a t em per atu re sen so r i s att ach ed) in degrees Fahrenheit or Celsius. To change the unit of measure, press MENU DOWN until the S YSTEM menu appears.
69 Speed and Distance Log Units of Measure The speed and distance log can be displayed in statute miles (MPH), Nautical miles (knots), or Metric (k ilometers per hour) if a speed sensor is attached. To change the unit of measure, press MENU DOWN until the S YSTEM menu appears.
70 Reset Log menu. Preset Unit (reset all options) This command is used to reset all fe atures, options and settings to their original factory defaults. This is us eful when you have changed several settings and want to return the uni t to basic automatic operation.
71 System Info To show the operating software system information, press MENU DOWN until the S YSTEM menu appears, then press UP A RROW . Press MENU DOWN until the S YSTEM I NFO screen appears. Press PWR to clear the screen. System Info screen. Simulator This unit has a built-in simulator th at shows a simulated bottom signal with fish signals.
72 Simulator menu. NOTE: If you turn on your unit before attaching a transducer, it may enter a demo mode. The words "demo mode" flash on the bottom of the screen and a sonar chart plays much like the simulator.
73 Chart Setup menu. Limit Search The Limit Search command helps yo u maintain maximum chart detail when you are moving fast in deep water (about 200 feet). When turned on, Limit Search prevents the digital sonar from over-riding the sonar chart's depth range setting.
74 The sonar chart must be in manual depth range mode to use the Limit Search command. To switch from au to depth range to manual, press MENU until the R ANG E menu appears. Use the arrow keys to select the desired range. When you're finished, press PWR to clear the menu from the display.
75 To change any of these options, press MENU DOWN until C HART S ETUP appears, then press UP A RROW . Use the MENU keys to cycle through the list and display the desired menu, then use the A RROW k e y s t o s e l e c t the desired number size or turn the numbers off.
76 Scales menu, with scale on (left) and off (right). With the scale off, only the upper and lower limits (zero and 60 in this case) are displayed To turn the scale off, press MENU DOWN until C HA RT S ETUP appears, then press UP A RROW . Press MENU DOWN until S CALES appears, then press DOWN A RROW to select U PPER L OWER O NLY .
77 Troubleshooting If your unit is not working, or if yo u need technical help, please use the following troubleshooting section be fore contacting the factory cus- tomer service department. It may save you the trouble of returning your unit for repair.
78 Weak bottom echo, digital readings erratic, or no fish signals: 1. Make sure the transducer is pointing straight down. Clean the face of the transducer.
79 2. Electrical noise from the boat's motor can interfere with the sonar. This causes the sonar to automatica lly increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display.
80 Sensitivity should be set at 90-95 percent. There should be a steady bottom signal on the display. Now turn on each piece of electrical equipment on the boat and view the effect on the sonar's display. For example, turn on the bilge pump and view the sonar display for noise.
