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 . When you come to a sonar menu comma nd on the LMS-320 screen, you can look it up in the manual by skimming over the table of contents, just flip- ping through Section 3 or scanning th [...]

3 Now, if you're into the fine details , glance over the next segment on specifications to see just how much sonar and GPS power your unit con- tains. It's important to us (and our power users), but, if you don't care how many watts of power the unit ha s, or how many waypoints LMS-320 can store, skip ahead to importan t information [...]

You can replay this sonar log in the unit using the Sonar Simulator function, or play it back on a personal computer using our free Sona r Viewer. The viewer is ava[...]

7 searching for businesses and addre sses — won't work without a custom MapCreate map. There is so much detail in our background map (and even more in MapCreate) that we' ll describe their contents and differ- ences in Section 6, Basic GPS Operations , on page 95. Another portion of LMS-320's on board memory is devoted to recording[...]

8 LMS-320 automatically reads Custom Map Files directly from the MMC or SDC. To use a custom map, all you need to do is slide an MMC containing a map into the unit. Introduction to GPS and WAAS Well, now you know the basics of how LMS-320 does its work. You might be ready to jump ahead to Section 2, Installation & Accessories, on page 13, so yo[...]

9 A minimum of three satellites are required to determine a 2D fix. The system requires signal receptio n from three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation (your height above sea level — also called altitude.) This is called a 3D fix. Remember, the un[...]

10 First, the U.S. government has not completed construction of the WAAS system, so it is not yet fully operational. The ground stations are in place, but only a few of the needed WAAS satellites have been launched. WAAS can boost the accuracy of land GP S navigation, but the system is designed for aircraft. The satellites are in a fixed orbit arou[...]

14 ducer does "kick-up," the bracket can easily be pushed back into place without tools. 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 transdu[...]

15 at speeds faster than 35 mph. Typi cally, a good location on alumi- num boats is between the ribs closest to the engine. 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, do[...]

16 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 com[...]

17 The following instructions sometime s vary depending on the mounting bracket that came with your transducer. Single-frequency Skimmers come with a one-piece stainless st eel bracket, while dual-frequency Skimmers come with a two-piece plastic mounting bracket. Use the set of instructions that fits your model. 1. Assembling the bracket. A. One-pi[...]

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.

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[...]
