To get started with your Eagle sonar, first read the installation section. It contains instructions for mounting the sonar unit, the transducer and any optional accessories, such as a speed sensor.
Operates at boat speeds up to 70 mph (61 kts). watts RMS power (typical). pends on transducer configuration and instal- lation, bottom composition and water condi- tions. All sonar units typically read deeper in fresh water than in salt water.
Surface water temp: ...Yes, built into transducer. Optional external Speed/distance log: ...Yes, with optional speed sensor. This manual covers the FishEasy 240 and FishEasy 240 Portable. Both units operate the same way. The only difference between the two is that the portable unit includes a portable transducer and other items that enable portable use.
The receiver amplifies this return signal, or echo, and sends it to the display, where an image of the object appears on the scrolling sonar chart. The sonar's microprocessor calculates the time lapse between the transmitted signal and echo return to determine the distance to the object.
You should read over this entire installation section before drill- ing any holes in your vehicle or vessel! 1. Determine the approximate location for the sonar unit, so you can plan how and where to route the cables for the transducer and power.
Depending on your sonar unit's connectors, your transducer cable may also have the sonar unit's power cable attached to it. If that is the case, be sure to install the transducer first, before connecting the power cable to a power source. See the instructions later in this manual for connect- ing the power cable to a battery or other power supply.
If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving.
5. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the trans- ducer cable around these wires.
Shoot-Thru-Hull vs. Transom Mounting In a shoot-thru-hull installation, the transducer is bonded to the inside of the hull with epoxy. The sonar "ping" signal actually passes through the hull and into the water. This differs from a bolt-thru-hull installa- Transducer...
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. This puts the transducer in direct con- tact with the water. Typically, shoot-thru-hull installations give excellent high speed opera- tion and good to excellent depth capability.
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.
Ratchets 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. Rubber washers Assemble transducer and bracket.
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 centerline 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.
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.
Align transducer centerline with hull bottom 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.
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.

Partial fish arches Transducer aimed Transducer aimed too far forward too far back Full fish arch Proper transducer angle 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.
The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass lay- ers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area.
1. Anchor the boat in about 30 feet of water. Add a little water to the sump of the boat. Plug the transducer into the sonar unit, turn it on, then hold the transducer over the side of the boat in the water. Adjust the sensitiv- ity and range controls until a second bottom echo is seen on the display.

hull. This is especially true if you have to turn sensitivity all the way up to get a decent bottom signal. 4. Most people can get good results by following steps 1 through 3, so this step is optional. If you want to make an extra effort to be absolutely sure that your selected location will work under all conditions, make a test run with the boat on plane and observe the bottom signal.
Sand this surface Orient the Skimmer with the nose facing the bow of the boat. 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.
Leave the weight in place for a minimum of three hours. Allow the epoxy to cure for 24 hours before moving the boat. 5. After the epoxy has cured, route the cable to the sonar unit and it's ready to use.
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.

Power/trans- ducer cable 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 inside the back cover of this manual.
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. Also make sure the lo- cation doesn't interfere with the boat's trailer.
This will help ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 5/8".

Mounting the Sonar Unit: In-Dash, Bracket or Portable You can install the sonar unit on the top of a dash with the supplied bracket. This unit can be installed in a dash with the optional FM-6 in- dash adapter kit.
(See the following drawings, which show the dimensions of a gimbal-mounted FishEasy 240 sonar unit.) Holes in the bracket’s base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin pan- els to reinforce the panel and secure the mounting hardware.

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. Make sure there is one washer on each side of the transducer, inside the bracket.
For more information on this, see the earlier segment on Transducer Orientation and Fish Arches. For more detailed instructions on installing the FishEasy 240 Portable unit, please refer to the PPP-12 Porta Power Pack instruction sheet packed with your unit.
The unit sounds a tone when you press 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 turn the unit on and off.
4. UP and DOWN ARROWS These keys appear in the manual text as these keys to adjust virtually every feature and function on the sonar unit. Memory This unit has permanent memory that saves all user settings, even when power is removed.
When the sonar unit is first turned on and the backlight menu disap- pears, the display screen shows the Full Chart Page, or mode. The Fish I.D. feature is off. The depth range shows on the depth scale on the right side of the screen.
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 from scrolling across the screen. This is useful when you want to "freeze" the picture to study it more closely.
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. The FishEasy 240 Page menu lets you select among the display modes, or pages.
The line at the top of the screen represents the surface. The bottom depth (as determined by the digital sonar) shows in the upper left corner. Full Chart page, showing digital depth at top and speed at bottom.
NOTE: Temperature, speed, and distance require a temperature or speed sensor. These may be optional equipment, depending on the sonar model you purchased. Large Digital page.
Range When turned on for the first time, the unit automatically adjusts the depth range according to water conditions. 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. To do this, press until the menu appears.
Zoom screen, showing Zoom menu and the 2X zoom indicator at the top right of the screen. To zoom the display, first press the pears. Use the arrow keys to select either 2X or 4X zoom, then press to clear the menu. When the display is in Zoom mode, the screen will show a zoom indica- tor box at the top right corner of the screen.
Fig. 1 In 34 feet of water, with the Range 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. With the unit in 4X zoom, press the down arrow key to look at the six fish along the ledge, then press the up arrow to pan up the water column to see four game fish threatening a school of forage fish.
Sensitivity Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time. There are situations when too much clutter appears on the screen. Decreasing the sensitivity can reduce the clutter and show the strongest fish ech- oes, if fish are present.
Bait school Thermo- cline with fish Fish arches Fig. 1 Fig. 3 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.
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.
Since Grayline shows the difference between strong and weak signals, adjusting the sensitivity may also require a different Grayline level. The level chosen by the sonar unit at power on is usually adequate for most conditions. Experiment with your unit to find the Grayline setting that's best for you.
To change the Grayline level, press pears. Press to increase the level or press UP ARROW 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.
At left, underwater scene in normal fish arch mode. Right, Fish I.D. Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it. However, locating fish by symbol only has some limitations.
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. So, practice with the unit in both the Fish I.D.

40 percent. When you are stationary and a fish swims through the sonar signal cone, the image appears on the screen as a long line in- stead of a fish arch. Reducing the chart speed may result in a shorter line that more closely resembles a regular fish return.
Noise Reject and ASP (Advanced Signal Processing) The ASP (Advanced Signal Processing) feature is a noise rejection system built into the sonar unit. It constantly evaluates the effects of boat speed, water conditions and electrical interference and automati- cally gives you the best display possible under most conditions.
ASP 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 pass- ing over the face of the transducer, even vibration from the engine. In all cases, noise can produce unwanted marks on the display.
Alarms The sonar unit has two different types 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.
Shallow Alarm To set the shallow alarm depth, press appears. HALLOW LARM Press to increase the shallow alarm's depth setting or press UP ARROW to decrease it.

Unit freezes, locks up, or operates erratically: 1. Electrical noise from the boat's motor, trolling motor, or an accessory may be interfering with the sonar unit. Rerouting the power and trans- ducer cables away from other electrical wiring on the boat may help.
1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets.
With the boat at rest in the water, the first thing you should do is turn all electrical equipment on the boat off. Make sure the engine is also off. Turn your sonar on, then turn off Noise Re- ject [also known as the ASP feature (Advanced Signal Processing)].
VHF radio antenna cables radi- ate noise when transmitting, so be certain to keep the sonar's wires away from it. You may need to route the sonar unit's power cable di- rectly to the battery to isolate it from other wiring on the boat.
