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. All you have to do is press the on (PWR) key. 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, s

This manual covers the Cuda 242 and Cuda 242 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. NOTICE! The storage temperature for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended storage in temperatures higher or lower than specified will damage the liquid crystal display in your unit. This type of damage is no

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. Determine the approximate location for the sonar unit, so you can plan how and where to route the cables for the transducer and power. This will help you make sure you have enough cable length for the de- sired configuration. 2. Determine the approximate location fo

These are all "kick-up" mounting brackets. 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. 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 t

mulated epoxy adhesive available from LEI (see ordering information on the inside back cover). A sandwich hull also requires polyester resin. Selecting a Transducer Location 1. The location must be in the water at all times, at all operating speeds. 2. The transducer must be placed in a location that has a smooth flow of water at all times. 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 rand

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 transducer cable around these wires. CAUTION: Clamp the trans- ducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed. Good location Poor location Good location Good location Poor angle Good and poor trans

Transom Transducer centerline Hull bottom Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be coming out of the water as you cross waves or wakes. Move the transducer a little lower to help prevent this. I

There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer. However, the shoot-thru-hull installation does have its drawbacks. First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish arches. This can be a problem on

Dot Align plastic ratchets in bracket. 2. Aligning the transducer on the transom. Slide the transducer between the two ratchets. Temporarily slide the bolt though the trans- ducer assembly and hold it against the transom. Looking at the trans- ducer from the side, check to see if it will adjust so that its face is par- allel to the ground. If it does, then the "A" position is correct for your hull. If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from t

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.

The transducer should be roughly parallel to 11

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. You will drill one hole in the center of each slot. Drill the holes. Use the #29 bit (for the #10 screws). Transom Transom Position transducer mount on transom and mark mounting holes.

Route cable over bolt and through bracket. Side view shown (left) and seen from above (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. Tighten the bracket's mounting screws, sealing them with the caulking compound. Adjust the transducer so that it's parallel to the ground and tighten the nut until it touches the outer washer, then add 1/4 turn. Don't over t

Bottom of hull Deep-"vee" hull Flat-bottom hull 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 you leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wiring. Electrical noise from the engine's wiring, bilge pumps, VHF radio wires, cables and aerators can be picked up by the sonar. Use caution when routing the transducer cable around

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. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go below the bottom of the hull! Trolling Motor Bracket Installation 1. Attach the optional TMB-S bracket to the transducer as shown in the following figure, using the hardware supplied with the transduc

3. Route the transducer cable alongside 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. Transducer mounted on trolling motor, side view.
