Eagle 2T - Manual

5 Good and poor transducer locations. How low should you go? For most situations, you should install your Skimmer transducer sothat its centerline is level with the bottom of the boat hull. This willusually give you the best combination of smooth water flow and protec-tion from bangs and bumps. Alig...

6 There are two extremes you should avoid. Never let the edge of themounting bracket extend below the bottom of the hull. Never let thebottom – the face – of the transducer rise above the bottom of the hull. Shoot-thru-hull vs. Transom Mounting Typically, shoot-thru-hull installations give excellent...

7 B. Two-piece bracket: Locate the four plastic ratchets in the trans- ducer's hardware package. Press two ratchets into the sides of the plas-tic bracket and two on either side of the transducer as shown in the fol-lowing illustrations. Notice there are letters molded into each ratchet. Place the r...

8 2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratch- ets. Temporarily slide the bolt though the transducer assembly andhold it against the transom. Looking at the transducer from the side,check to see if it will adjust so that its face is par...

9 parallel with the ground. If you can, then go to step 3B. If it doesn't,repeat step 2B, but use a different alignment letter until you canplace the transducer on the transom correctly. Assemble transducer and bracket. 3. Assembling the transducer. A. One-piece bracket: Once you determine the corre...

10 Mark the center of each slot for the mounting screw pilot holes. Youwill drill one hole in the center of each slot. Drill the holes. For the one-piece bracket, use the #29 bit (for the #10screws). For the two-piece bracket, use the #20 bit (for the #12screws). Position transducer mount on transom...

11 Both bracket types: Attach the transducer to the transom. Slide thetransducer up or down until it's aligned properly with the bottom ofthe hull as shown in the preceding and following figures. Tighten thebracket's mounting screws, sealing them with the caulking compound. Adjust the transducer so ...

12 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 thetransducer bracket to go ...

13 TRANSDUCER ORIENTATION AND FISH ARCHES If you do not get good fish arches on your display, it could be becausethe transducer is not parallel with the ground when the boat is at restin the water or at slow trolling speeds. Transducer angles and their effects on fish arches. If the arch slopes up –...

14 transducer installation can be made on hulls with flotation materials(such as plywood, balsa wood or foam) between layers of fiberglass ifthe material is removed from the chosen area. Epoxy the transducer to a solid portion of the hull. For example, some (but not all) manufacturers use a layer of...

16 Place the transducer into the epoxy, twisting and turning it to forceany air bubbles out from under the transducer face. The face of thetransducer should be parallel with the hull, with a minimum amountof epoxy between the hull and transducer. After the epoxy dries,route the cable to the sonar un...

20 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 ensurea 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 t...

43 ASP is an effective tool in combating noise. In sonar terms, noise is anyundesired signal. It is caused by electrical and mechanical sources suchas bilge pumps, engine ignition systems and wiring, air bubbles passingover the face of the transducer, even vibration from the engine. In allcases, noi...
