Section 1: Read Me First! How this manual can get you out on the water, fast! Welcome to the exciting world of digital sonar! We know you're anxious to begin finding fish, but we have a favor to ask. Before you grab your unit and begin installing it, please give us a moment or two to explain how our manual can help you get the best performance from your compact, wide-screen, fish finder. First, we want to thank you for buying a Lowrance sonar.
If you're having difficulty with your sonar, you can find an answer to the most common problems in Section 5, Sonar Troubleshooting. Finally, in Section 6, we offer Supplemental Material, including a list of warranty and customer service information. Now, if you're into the fine details, glance over the next segment on specifications to see just how much sonar power your unit contains.
Transmitter: ................... X136DF, X135 and X126DF: 4,000 watts peak-to-peak/500 watts RMS. X125: 2,400 watts peak-to-peak/300 watts RMS. Sonar sounding depth capability: ........... X136DF: 2,500 feet (762 meters). X126DF: 1,700 feet (518 meters). X135: 1,000 feet (305 meters). X125: 800 feet (244 meters). Actual capability depends on transducer configuration and installation, bottom composition and water conditions. All sonar units typically read deeper in fresh water than in salt water.
1957.) A sonar consists of a transmitter, transducer, receiver and display. In simple terms, here's how it finds the bottom, or the fish: The transmitter emits an electrical impulse, which the transducer converts into a sound wave and sends into the water. (The sound frequency can't be heard by humans or fish.) The sound wave strikes an object (fish, structure, bottom) and bounces back to the transducer, which converts the sound back into an electrical signal.
Instructions = Menu Sequences Most functions you perform with the sonar unit are described as a sequence of key strokes and selecting menu commands. We've written them in a condensed manner for quick and easy reading. For example, instructions for turning on the Fish ID feature would look like this: 1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT. 2. Press → to FISH SYMBOLS|ENT|EXIT|EXIT. Translated into complete English, step 1 above would mean: "Start on the Sonar Page.

Section 2: Installation & Accessories Preparations You can install the sonar system in some other order if you prefer, but we recommend this installation sequence: Caution: You should read over this entire installation section before drilling any holes in your vessel! 1. Determine the approximate location for the sonar unit, so you can plan how and where to route the cables for the transducer and power. This will help you make sure you have enough cable length for the desired configuration. 2.
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. Recommended Tools and supplies If you prefer the option of routing the cable through the transom, you will need a 1" drill bit. A transom mount requires use of a high quality, marine grade above- or below-waterline caulking compound.
3. If the transducer is mounted on the transom, make sure it doesn't interfere with the trailer or hauling of the boat. Also, don't mount it closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation. 4. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen.
quently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross waves or wakes. Move the transducer a little lower to help prevent this. If you cruise or fish around lots of structure and cover, your transducer may be frequently kicking up from object strikes. If you wish, you may move the transducer a little higher for more protection. There are two extremes you should avoid.
Dot Align plastic ratchets in bracket. B. Two-piece bracket: Locate the four plastic ratchets in the transducer's hardware package. Press two ratchets into the sides of the plastic bracket and two on either side of the transducer as shown in the following illustrations. Notice there are letters molded into each ratchet. Place the ratchets into the bracket with the letter "A" aligned with the alignment mark molded into the bracket.
Transducer bracket Transducer 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 ratchets. 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. If it does, then the "A" position is correct for your hull.
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. If it does, then the "A" positions are correct for your hull.
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. The transducer's centerline should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Mark the center of each slot for the mounting screw pilot holes.
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 transducer 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 MOTOR BRACKET INSTALLATION (single-frequency only) 1.
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 the ground when the boat is at rest in the water or at slow trolling speeds. Partial fish arches Transducer aimed too far back Transducer aimed too far forward Full fish arch Proper transducer angle Transducer angles and their effects on fish arches.
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 polyester resin Flotation material Epoxy to hull first Inner hull Outer hull 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.
cation that shot through the hull the best and follow the instructions on the following pages for a shoot-thru-hull mounting. Transducer location (high speed) Transducer location (trolling 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. Speed/Temperature Sensors This unit accepts up to three temperature sensors which can monitor surface water, live well, bait well and virtually any other temperature.

Optional Speed Sensor Installation All the units in this series can display speed and distance traveled, but only the X126DF and X136DF come packed with a speed sensor. 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. Recommended tools for this job include: drill, 7/8" drill bit, 1/8" drill bit for pilot holes, screwdriver.
If the base of the transom has a radius, fill the gap between the transom 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. If you need to drill a hole in the transom to pass the connector through, the required hole size is 7/8". Caution: If you drill a hole in the transom for the cable, make sure it is located above the waterline.
lead, black is negative or ground. Make sure to attach the in-line fuse holder to the red lead as close to the power source as possible. For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. It uses a 3-amp fuse.

Mounting the Unit: Bracket, In-Dash or Portable You can install the sonar unit on the top of a dash with the supplied gimbal bracket. It can also be installed in the dash or mounted on a portable power supply. If you use the supplied bracket, you may be interested in the optional R-A-M bracket mounting system.
Optional R-A-M mounting system. Bracket Installation Mount the unit in any convenient location, provided there is clearance behind the unit when it's tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power and transducer cables. (A drawing on the next page shows the dimensions of a gimbal-mounted sonar unit.) Holes in the bracket's base allow wood screw or through-bolt mounting.

Section 3: Basic Sonar Operation This section addresses the unit's most basic sonar operations. The instructions presented here in Sec. 3 follow a chronological order. Sec. 4, Sonar Options & Other Features, will discuss options and other more advanced functions and utilities. The material in Sec. 4 is arranged in alphabetical order. Before you turn on the unit, it's a good idea to learn about the different keys, the Main Menu, the Sonar Menu, the five Page options and how they all work together.
4. ARROW KEYS – These keys are used to navigate through the menus, make menu selections, move the sonar chart cursor and enter data. 5. ENT (Enter) – This key allows you to accept values or execute menu commands. 6. EXIT – The Exit key lets you return to the previous screen, clear data or erase a menu. 7. ALARM – The Alarm key is a quick shortcut to the sonar alarms menu. It allows you to choose which alarms to use and when. 8. ZOUT – (Zoom Out) – This key lets you zoom the screen out.
Main Menu. Main Menu Commands There are four "basic" Main Menu commands that you'll really want to read more about. They are: • Screen command: changes the contrast or brightness of the display screen. Use this command to adjust how the screen looks under various lighting conditions. • Sounds command: enables or disables the sounds for key strokes and alarms, controls the volume and sets the alarm style.
• Reset Water Distance command: resets water distance log to zero. • Sonar Simulator command: turns the simulator feature on and off. Useful for learning how to operate the unit and all its functions. • Transducer Type command (dual-frequency units only): sets the type of transducer plugged into the unit. • Reset Options command: returns all options and auto functions to their original factory settings. It's a great safety net while you're learning and experimenting with various settings.
• Auto Depth Range command: automatically sets the depth range shown on the sonar chart to always keep the bottom in view. • Upper and Lower Limits command: sets the upper and lower depth limits of the sonar chart. Lets you zoom in on a specific portion of the water column. • Stop Chart command: stops the sonar chart from scrolling. Used when you want to "freeze" the image for closer study. • Chart Speed command: sets the scrolling speed of the sonar chart.
The Full Sonar Chart is the main display option. This is a "crosssection" view of the water column beneath the boat. The chart moves across the screen, displaying sonar signal echoes that represent fish, structure and the bottom. Surface signal Surface clutter Digital data overlay (depth & temperature) Depth scale In FasTrack, fish arches show as horizontal bars.

Sonar chart display options (from left) digital data and FlashGraf. You can customize how the Sonar Page pictures and other data are displayed in many ways. We'll discuss all of those features and options in Section 4, but to show you how easy the sonar unit is to operate, the following page contains a simplified, 10-step quick reference that will cover most fish finding situations.
Basic Sonar Quick Reference 1. Mount the transducer and unit. Connect the unit to electric power and the transducer. 2. Launch your boat. 3. To turn on the unit, press and release PWR key. 4. Head for your fishing grounds. Your unit automatically displays digital depth and surface water temperature in the corner of the screen. The auto settings will track the bottom, displaying it in the lower portion of the screen.
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 — Sensitivity. Sensitivity controls the unit's ability to pick up echoes. If you want to see more detail, try increasing the sensitivity, a little at a time.
You can change the sensitivity level whether you are in Auto Sensitivity mode or Manual Sensitivity mode. The adjustment method works the same in both modes, but it gives you slightly different results. Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting 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.
NOTE: If you want to change the sensitivity in Manual Mode, first turn off Auto Sensitivity: from the Sonar Page, press MENU|↓ to AUTO SENSITIVITY|ENT|↑ to SENSITIVITY|ENT. Press ↓ or ↑ to pick a different sensitivity setting. When it's set at the desired level, press EXIT. Important Tip: While you are experimenting and learning, it's possible to scramble the settings so that the sonar picture disappears from your screen.
Other Free Training Aids The sonar options section discusses Fish I.D., fish alarms and other features in greater detail. If you or a friend has Internet access, you can also learn more about interpreting what you see on your sonar screen. Visit our web site, WWW.LOWRANCE.COM. Be sure to check out the free Sonar Tutorial, which includes animated illustrations and more pictures of actual sonar returns, all described in detail.
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. This automatic feature gives you the best display possible under most conditions. The ASP feature is an effective tool in combating noise. In sonar terms, noise is any undesired signal.
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. Any echo on the chart that appears inside this bar triggers this alarm. The last alarm is the Depth Alarm, which has both a Shallow and a Deep setting. Only the bottom signal will trigger this alarm.
5. To turn off the alarm, press ALARM|ENT|EXIT. To switch to a different depth setting, open the Sonar Alarms menu and repeat the instructions in step 3 above. To adjust and turn on the deep alarm: 1. Press ALARM. 2. Press ↓ to DEEP ALARM ENABLED|→ to DEEP ALARM DEPTH|ENT. 3. Press ↑ or ↓ to change the first number, then press → to move the cursor to the next number and repeat until the depth is correct, then press ENT. 4. Press ← to DEEP ALARM ENABLED|ENT|EXIT. 5.

This enlarges the sonar targets to best suit your fishing needs and water conditions. At left, Sonar Page Menu with Upper and Lower Limits command selected. At right, Sonar Chart Limits menu, with Upper Limit selected. To change the upper and lower limits: 1. From the Sonar Page, press MENU|↓ to UPPER AND LOWER LIMITS|ENT.
To turn off upper and lower limits: 1. From the Sonar Page, press MENU|↓ to AUTO DEPTH RANGE|ENT|EXIT. 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 continues to operate normally. FasTrack gives you a rapid update of conditions directly under the boat. This makes it useful for ice fishing, or when you're fishing at anchor.
You may see fish symbols on the screen when actually, there are no fish. The reverse is also true. The illustrations on the next page show how Fish I.D. can actually miss fish that are present. Does that mean Fish I.D. is broken? No — the feature is simply interpreting 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.

Frequency (Change Transducer Frequency) (X126DF and X136DF only) The "DF" in your unit's name refers to its dual-frequency transducer, which operates with both 200 kHz and 50 kHz. The 200 kHz frequency has a 12° cone angle and the 50 kHz frequency has a 35° cone angle. The default frequency is 200 kHz, which is best for use in shallow water (about 300 feet or less). This frequency is the best choice for about 80 percent of the fresh and salt water sport fishing applications.
To change the frequency setting to 200 kHz: 1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT. 2. Press →|then press ↓ to 200 KHZ|ENT. 3. Press EXIT|EXIT to clear the menu. Grayline Grayline lets you distinguish between strong and weak echoes. It "paints" gray on targets that are stronger than a preset value. This allows you to tell the difference between a hard and soft bottom. For example, a soft, muddy or weedy bottom returns a weaker signal which is shown with a narrow or no gray line.

Ping Speed & HyperScroll Ping Speed controls the rate at which the transmitter and transducer broadcast sonar sound waves — pings — into the water. The unit has a default ping speed of 50 percent. At normal boating speeds, this automatically provides enough return echoes to refresh the screen and scroll the chart at maximum chart speed. However, when you are running at high speeds, or just want the fastest possible screen update, you may want to use the HyperScroll feature.
To adjust Sensitivity: 1. From the Sonar Page, press MENU|ENT. 2. The Sensitivity Control Bar appears. Press ↓ to decrease sensitivity; press ↑ to increase sensitivity. When it's set at the desired level, press EXIT. (When you reach the maximum or minimum limit, a tone sounds.) To turn off HyperScroll: 1. From the Sonar Page, press MENU|↓ to PING SPEED|ENT. 2.

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. Unit won't turn on: 1. Check the power cable's connection at the unit. Also check the wiring. 2. Make sure the power cable is wired properly.
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. It may change the range to limits far greater than the water you are in. If this happens, place the unit in the manual mode, then change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity. As you move into shallower water, a bottom signal should appear. 4.
To eliminate or minimize the effects of electrical noise, first try to determine the cause. With the boat at rest in the water, the first thing you should do is turn all electrical equipment on the boat off. Make sure the engine is also off. Turn your sonar on, then turn off Noise Reject [also known as the ASP feature (Advanced Signal Processing)]. Sensitivity should be set at 90-95 percent. There should be a steady bottom signal on the display.
