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. All you have to do is...

3 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...
Page 8: Transducer Installation
4 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 ca...

5 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...

9 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 d...

15 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 ...

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. You'll need to ...
