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 degr[...]

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 can plan how and where to route the cables for the t[...]

5 These are all "kick-up" mounting brac kets. They help prevent dam age 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 conne ctors, your transducer cable may also have the sonar u[...]

6 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 th[...]

7 5. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wi ring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the transducer cable around these wires. Good and poor transducer locations. How low should you go? For most situations, you should in s[...]

8 Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slot s in the mounting brackets allow you to loosen the screws and slide the tr ansducer up or down.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be comi[...]

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 different installations on the same hull. This[...]

10 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 doe[...]

11 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. 4. Drilling mounting holes. Hold the transducer and bracket assem-[...]

12 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. You will drill one hole in the center of each slot. Drill the holes. Use the #29 bit (for the #10 screws). Position transducer mount on t[...]

13 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 caulki[...]

14 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 wire[...]

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 go below the bottom of the hull! Trolling Mot[...]

16 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. Transducer mounted on tro lling motor, sid[...]

17 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 the transducer is angled too far down and needs to be raised. NOTE: Periodically wash the transducer's face[...]

18 Shoot-Thru-Hull Preparation Hulls w ith Flotation Materials 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 th rough solid fiberglass. A successful transducer installation can be made on hulls with flotation materials [...]

19 sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals. Testing Determines Best Location Ideally, the shoot-thru transducer shou ld be installed as close to the transom as possible, close to the ce nterline. This will give you the best performance during high spe[...]

Next, take the transducer out of the water and place it in the water in the sump of the boat, face down. (The transducer face is shown in the figure on the following page.) Notice how the signal strength decreases. The [...]

21 4 . Most people can get good results by following steps 1 through 3, so this step is optional . If you want to make an extr a 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 figure some way to prop the transducer int[...]

22 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. 2. The epoxy consists of the epoxy itself and a hardener. Remove the two compounds from the[...]

23 Make sure there are no air pockets in the epoxy layer! Then, apply the remaining epoxy to the sanded area on the hull. 3. Press the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. Stop pressing when you bottom out on the hull. When you're finished, the face of the trans- ducer [...]
