vi WARNING! A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION When showing navigation data to a position (waypoint), a GPS unit will show the shortest, most direct path to the waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigator will not only tak[...]

1 Section 1: Read Me First! How this manual can get you out on the road, fast! Welcome to the exciting world of digital sonar and GPS! We know you're anxious to begin navigating and finding fish, but we have a favor to ask. Before you grab the unit and begin installing it, please give us a moment or two to explain how ou r manual can help you [...]

2 After you've gained some experience with your sonar, you'll want to check out Section 4, which discusses more advanced Sonar Options and Other Features .

13 Section 2: Installation & Accessories Preparations You can install the sonar and GPS sy stems in some other order if you prefer, but we recommend this installation sequence: CAUTION: You should read over this entire installation section before drill- ing any holes in your vehicle or vessel! 1. Determine the approximate locati on for the sona[...]

14 Read these instructions carefully before attempting the installation. Determine which of the mounting posi tions is right for your boat. Use extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer installation is the most critical part o[...]

15 2. The transducer should be insta lled with its face pointing straight down, if possible. 3. If the transducer is mounted on th e transom, make sure it doesn't inter- fere with the trailer or hauling of the boat. Also, don't mount it closer than approximately one foot from th e engine's lower unit. This will pre- vent cavitation ([...]

16 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 coming out of the water as you cross waves or wak[...]

18 Add ratchets to bracket and transducer. 2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratch- ets. Temporarily slide the bolt th ough the transducer assembly and hold it against the transom. Lookin g at the transducer from the side, check to see if it will adjust so that its face is parallel[...]

19 B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temporarily slide the bolt though the transducer assembly but don't tighten the nut at this time. Hold the assembled transducer and bracket against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face [...]

20 B. Two-piece bracket: Once you determine the correct position for the ratchets, assemble the transduc er as shown in the figure in step 2B. Don't tighten the lock nut at this time. 4. Drilling mounting holes. Hold the transducer and bracket a ssembly against the transom. The transducer should be roughly pa rallel to the ground. The trans- d[...]

21 Both bracket types: 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[...]

22 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 ca using the noise. Don't allow the transducer bracket to go below the bottom of the hull! TROLLING MO[...]

23 TRANSDUCER ORIENTATION AND FISH ARCHES If you do not get good fish arches on your display, it could be because the transducer is not parallel with th e ground when the boat is at rest in the water or at slow trolling speeds. Transducer angles and their effects on fish arches. If the arch slopes up – but not back down – then the front of the [...]

24 transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or fo am) between layers of fiberglass if the 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 fiberglass, then a core of balsa wood, finishi[...]
