A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. 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.
The manual is organized into 10 sections. This first section is an intro- duction to the LCX-104C sonar and GPS. It tells you the basics you need to know before you can make the unit look around and tell you where you are, or look below the surface to find some fish.
Page 10
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 command on the unit's screen, you can look it up in the manual by skimming over the table of contents, just flip- ping through Section 3 or scanning through the sonar options in Section 4.

The performance doesn't stop there. Stored in the permanent memory of every unit is a basic background map of the entire world. We lock it in here at the factory — you can't change or erase this map. The background map is suitable for many navigation chores, but for maximum accuracy and much more detail, you need our optional map- making software, MapCreate...
MMC, custom map files and GPS data files can be used interchangea- bly between your gimbal-mounted LCX-104C and the hand-held iFINDER GPS receiver.) The unit 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 con- taining a map into the unit.

A minimum of three satellites are required to determine a 2D fix. Remember, the unit must have a clear view of the satellites in order to receive their signals. Unlike radio or television signals, GPS works at very high frequencies. These signals can be easily blocked by trees, buildings, an automobile roof, even your body.
WAAS reception, but terrain, foliage or even large man-made structures frequently block the WAAS signal from ground receivers. You'll find that using your GPS receiver is both easy and amazingly accurate. It’s easily the most accurate method of electronic navigation available to the general public today.

Installation & Accessories Preparations You can install the sonar and GPS systems 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.
Read these instructions carefully before attempting the installation. Determine which of the mounting positions 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 of a sonar installation.
2. The transducer should be installed with its face pointing straight down, if possible. 3. If the transducer is mounted on the 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 the engine's lower unit.
However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer 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 wakes.

Transducer Transducer bracket Ratchet Ratchet 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 though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground.
Page 27
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 is parallel to the ground.
Page 28
B. Two-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer 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 assembly against the transom. The transducer should be roughly parallel to the ground.
Page 29
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 and tighten the nut until it touches the outer washer, then add 1/4 turn.
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!

transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area. Fill with epoxy Flotation material Epoxy to hull first 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, finishing with an outer layer of fiberglass.

Transducer location (high speed) Shoot-thru-hull transducer locations for high speed or trolling speed operation. Shoot-thru-hull Installation 1. Make sure the area is clean, dry and free of oil or grease, then sand both the inside surface of the hull and the face of the transducer with 100 grit sandpaper.
Place the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. The face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. After the epoxy dries, route the cable to the sonar unit.

Optional Speed Sensor Installation This unit can display speed and distance traveled; the feature requires a speed sensor which may or may not come packaged with your unit. (If you wish to purchase an optional additional sensor for your unit, refer to the accessory ordering information inside the back cover of this manual.) The following instructions describe how to install the speed sensor.
Transom Speed sensor mounting configuration: side view (left) and rear view (right.) 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 ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit.
You need to select an antenna installation location that has a clear, un- obstructed view of the sky. After the module is installed, route the cable to the unit, plug it in the center socket on the back and your system is ready to use.
The most popular DGPS system relies on a grid of ground-based trans- mitters that send correction signals to DGPS receivers. These in turn, connect to the GPS receiver (such as the LCX-104C). Lowrance offers an optional DGPS receiver for your unit.

Sonar Operations As you can see from the quick reference on the previous page, basic operation is pretty easy, right out of the box. If you are a sonar novice, try operating the unit with the factory defaults until you get a feel for how it's working. As you're learning the basics, there is one setting you might want to tinker with from time to time —...

Adjusting sensitivity in Auto Sensitivity Mode is similar to manually ad- justing a car's speed with the accelerator pedal while cruise control is on. You can tell the car to run faster, but when you let off the gas the cruise control automatically keeps you from running slower than the minimum speed setting.
Important Tip: While you are experimenting and learning, it's possible to scramble the settings so that the sonar picture disappears from your screen. If that happens, remember that it's easy to switch back to full automatic operation by simply restoring the factory auto settings. Here's how: To Restore Factory Settings 1.

Section 4: Sonar Options & Other Features Material in this section is arranged in alphabetical order. ASP (Advanced Signal Processing) The ASP feature is a noise rejection system built into the sonar unit that constantly evaluates the effects of boat speed, water conditions and interference.
Alarms This unit has three different types of sonar alarms. The first is the Fish Alarm. It sounds when the Fish I.D. feature determines that an echo is a fish. Another alarm is the Zone Alarm, which consists of a bar on the side of the screen.

Page 70
Changing the upper and lower limits gives you far greater control over the depth range. This feature lets you "zoom in" the display in almost unlimited combinations. Nearly any segment of the water column, from the surface to the bottom can be shown. This enlarges the sonar targets to best suit your fishing needs and water conditions.
To turn off upper and lower limits: From the Sonar Page, press FasTrack This feature automatically converts all echoes to short horizontal lines on the display's far right side. The graph on the rest of the screen con- tinues to operate normally. FasTrack gives you a rapid update of condi- tions directly under the boat.
Page 72
Does that mean Fish I.D. is broken? No — the feature is simply inter- preting sonar returns in a specific way to help take some of the work out of reading the screen. Remember: Fish I.D. is one of the many tools we provide so you can analyze your sonar returns for maximum fish finding information.
To turn the Fish I.D. feature on: 1. From the Sonar Page, press 2. Press → ↓ or → to To turn off Fish I.D., repeat the instructions in step 1. FishTrack The FishTrack feature shows the depth of a fish symbol when it ap- pears on the display.
The 200 kHz transducer will give you better detail and definition, but less depth penetration. The 50 kHz transducer will give you greater depth penetration, but a little less detail and less definition. (Remember, all sonar units typically read deeper in fresh water than in salt water.) There is a common exception to these rules of thumb.

However, when you are running at high speeds, or just want the fastest possible screen update, you may want to use the HyperScroll feature. When you change the Ping Speed to any setting greater than 50 per- cent, the unit automatically enters HyperScroll mode. These faster ping rates allow you to maintain a high-detail picture on the screen, and the screen refresh rate and chart scroll speed can keep pace with the boat as it moves quickly over the bottom terrain.
When you boost ping speed and switch into HyperScroll, the width of the FasTrack bar graph display doubles in width at the right side of the screen. The allows you to better see the virtually instantaneous sonar returns, just as you would on a flasher sonar unit. For more informa- tion on FasTrack, see it's entry in this section.
Set Keel Offset This unit measures water depth from the face of the transducer. Since the transducer is installed below the water surface, the distance dis- played by the digital depth, chart depth scale, chart cursor or fish sym- bols is not the exact water depth. If the transducer is 1 foot below the surface, and the screen shows the water depth as 30 feet, then the ac- tual depth is 31 feet.

Section 5: Sonar Troubleshooting If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit for repair. For contact information, refer to the last page, just inside the back cover of this manual.

This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display. 3. The water may be deeper than the sonar's ability to find the bottom. If the sonar can't find the bottom signal while it's in the automatic mode, the digital sonar display will flash continuously.
Page 97
NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonar's display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause the unit to operate erratically, or not at all. To eliminate or minimize the effects of electrical noise, first try to determine the cause.
