Introduction Thank you for buying a Lowrance sonar! Your unit is a high-quality, remarkably-priced color sonar designed for both professional and novice fishermen. All Lowrance sonars have an automatic mode that finds and displays the bottom, fish, underwater structure and more – right out of the box. All you have to do is press the on (MENU/PWR) key. However, if you want to fine-tune your unit, press the MENU key again.
Sonar Frequency:...................... 200 kHz. Transducers: .................. A model HST-WSU Skimmer transducer comes packed with your sonar unit. Operates at speeds up to 70 mph (61 kts). Optional thruhull, portable and trolling motor transducers are available. Transmitter: ................... 800 watts peak-to-peak power (typical); 100 watts RMS power (typical). Sonar sounding depth capability: ........... 600 feet (182 meters).
(Lowrance developed the world's first transistorized sportfishing sonar in 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.
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 ID SYMBOLS|ENT|EXIT|EXIT. Translated into complete English, step 1 above would mean: "Start on the Sonar Page.
Installation and Accessories Installation 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.
speed or temp sensor and route its cable through the same hole in the transom, you will need a 1" (25.4 mm) drill bit to accommodate all the cables.) The following installation types also call for these recommended tools and required supplies (supplies are not included): Transom installation Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flathead screwdriver. Supplies: high quality, marine grade above- or belowwaterline caulking compound.
CAUTION: Clamp the transducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed. Good location Poor location Good location Good location Poor angle Good and poor transducer locations. How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull.
Shoot-thru-hull vs. Transom Mounting Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. 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.
holes in the bracket with the letter "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3. If it doesn't, repeat step 2, but use a different alignment letter until you can place the transducer on the transom correctly. Ratchets Insert bolt and check transducer position on transom. 3. Assembling the transducer.
Transom Transom Position transducer mount on transom and mark mounting holes. Side view shown at left and seen from above at right. 5. Attaching transducer to transom. Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown in the following figures. Route cable over bolt and through bracket. Side view shown at left and seen from above at right. Attach the transducer to the transom.
6. Route the transducer cable through or over the transom to the sonar unit. Make sure to leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engine's wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires. WARNING: Clamp the transducer cable to the transom close to the transducer.
3. Route the transducer cable alongside 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 trolling motor, side view.
If the arch slopes up – but not back down – then the front of the transducer 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 with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity or may even prevent operation.
of the boat. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (You will need to turn off both Automatic Sensitivity and ASP.) Don't touch the controls once they've been set. Next, take the transducer out of the water and place it in the water in the sump of the boat. Observe the sonar signal to see if there is a noticeable decrease in sensitivity. The second bottom signal may disappear and the bottom signal may decrease in intensity.
Spread epoxy here Sand this surface Epoxy transducer to hull. 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, remember to fill in the area around the transducer with more epoxy and route the cable to the sonar unit.

Speed Sensor Installation If you wish to purchase an optional 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, 5/8" drill bit, 1/8" drill bit for pilot holes, screwdriver. Required supplies for this job include: four #8 stainless steel wood screws (3/4" long), high quality, marine grade aboveor below-waterline caulking compound.
Transom Bottom of hull Bottom of hull 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 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 5/8". (The hole is 1" (25.
If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and installing an inline switch. This will let you shut off power to the power cable when the unit is not in use. When you are not using the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit.
ity of this kit, refer to the accessory ordering information inside the back cover of this manual. Bracket Installation Recommended tools for this job include: drill, 1" (25.4 mm) drill bit, screwdriver. Required supplies for this job include: high quality, marine grade above- or below-waterline caulking compound, three #10 stainless steel screws. Screw length and type should be suitable for the material on which you intend to mount the bracket.
After drilling the hole, pass the connectors up through the hole from under the dash. If you wish, you can fill in the hole around the cable with a good marine caulking compound. (Some marine dealers stock cable hole covers to conceal the opening.) Using the Quick Release Mounting Bracket These units use a quick release mounting bracket. When you run the cables through the bracket's cable slots, make sure you allow enough slack for tilting the unit and attaching the connector.
Bracket front Mount the sonar: slide the unit onto the bracket from above. Depress ratchets to release Adjust viewing angle: use one hand to press and release the springloaded ratchets while you move the unit with the other hand. Portable Sonar Installation Like many Lowrance products, the X67C sonar is capable of portable operation. It uses the optional PPP-12 portable power pack. The power pack and portable transducers expand the uses for your sonar.
To use a portable power pack, you simply install the batteries and then attach the sonar unit to the power pack's bracket. Plug in the power/transducer cable and you're ready to fish. The PPP-12 has a quick-release mounting bracket built into the case. Installing the Batteries Release the latch on the front of the power pack case. Open the compartment and install eight AA batteries into the adapter. For the longest life, we recommend you use alkaline batteries.
power cable should be attached to the red wire on the battery adapter and the power cable's black wire should be connected to the black wire on the battery adapter. If it still doesn't work, check the battery voltage. Most of the complaints we receive about portable units result from stale batteries. Make sure the ones you buy are fresh. In cold weather the efficiency of dry cell batteries drops with the temperature.

Clean the chosen area of the hull before attaching the suction cup. Locate the transducer on the hull as shown in the following figure. Don't allow the bracket to extend below the hull, because water pressure against it can cause the suction cup to come off at speed. Moisten the cup, then press it onto the hull as firmly as possible.
Basic Sonar Operation KEYBOARD BASICS The unit sounds a tone when you press any key. This tells you the unit has accepted a command. Numbers in the photo correspond to key explanations below: 2 1 4 3 Lowrance X67C Sonar, front view, showing screen and keyboard. 1. MENU/PWR (menu and power) This key appears in the manual text simply as MENU. Press this key to turn the unit on and off.
2. ENT/PAGES (enter and pages) This key appears in the manual text simply as ENT. When viewing a menu or adjusting a feature, use this key to select a highlighted option. When no menus are on the screen, pressing this key will make the unit cycle through the four Sonar Chart Display Options. 3. EXIT Press this key to clear menus from the screen and return to the Sonar Chart display. You will also use EXIT to cancel alarms, and to clear any information windows that may appear on the screen. 4.
Main Menu. Main Menu Commands There are four "basic" Main Menu commands that you'll really want to read more about. They are: • Screen commands (CONTRAST, BACKLIGHT LEVEL and TRANSPARENCY): change the appearance of the display screen. Use these commands to adjust how the screen looks under various lighting conditions. • Volume command: controls sound levels for key strokes and alarms. If you don't like to hear a beep each time you press a key, you can turn all sounds off by setting the volume to zero.
• Set Keel Offset command: calibrates the unit to show depth under the keel or actual depth from the surface. • Calibrate Water Speed command: adjusts how a speed sensor measures water speed. • 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. • Reset Options command: returns all options and auto functions to their original factory settings.
tion, but Sensitivity and Auto Sensitivity are important basic functions that are discussed both here and in the Advanced Section. The other Sonar Menu commands include: • ColorLine command: separates fish and structure near the bottom from the actual bottom, and defines bottom composition/hardness. • Depth Range command: manually sets the depth range shown on the sonar chart. • Auto Depth Range command: automatically sets the depth range shown on the sonar chart to always keep the bottom in view.

Sonar chart display options (from left) digital data and flasher. 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 the Advanced Section, 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 MENU 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 following 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.
Advanced 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 two different types of sonar alarms. The first is a Fish Alarm. It sounds when the Fish I.D. feature determines that an echo is a fish. The other alarm is the Depth Alarm, which has both a Shallow and a Deep setting. Only the bottom signal will trigger this alarm. This is useful as an anchor watch, a shallow water alert or for navigation.
To adjust and turn on the deep alarm: 1. Press MENU|MENU|↓ to SONAR ALARMS|ENT. 2. Press ↓ to DEEP ALARM DEPTH|ENT. 3. Press ↑ or ↓ until the depth is correct, then press ENT. 4. Press ↑ to DEEP ALARM ENABLED|ENT|EXIT. 5. To turn off the alarm, press MENU|MENU|↓ to SONAR ALARMS|ENT|↓ to DEEP ALARM ENABLED|ENT|EXIT. To switch to a different depth setting, open the Sonar Alarms menu and repeat the instructions in step 3 above.
Backlight Level Command, left, and Backlight Level control bar, right. The control bar appears automatically whenever you turn on the unit. Calibrate Speed The speed sensor can be calibrated to compensate for inaccuracies. Before you change the setting, first calculate the percentage that the speed is off. You will enter this percentage in a moment. For example, if you figure the sensor is reading 10 percent faster than actual speed, you will enter – 10 in the calibration window.
speed around 75 percent. When you are stationary and a fish swims through the sonar signal cone, the image appears on the screen as a long line instead of a fish arch. Reducing the chart speed may result in a shorter line that more closely resembles a regular fish return. At left, Sonar Page menu with Chart Speed command selected. At right, Chart Speed Control Bar. If you do experiment with chart speed, remember to reset it to maximum when you resume trolling or moving across the water at higher speed.
ColorLine is adjustable. Experiment with your unit to find the ColorLine setting that's best for you. At left, Sonar Page menu with ColorLine command selected. At right, the ColorLine control bar. To adjust the ColorLine level: 1. From the Sonar Page, press MENU|↓ to COLORLINE|ENT. 2. The ColorLine Control Bar appears. Press ↓ to decrease ColorLine; press ↑ to increase Colorline. 3. When it's set at the desired level, press EXIT.
Contrast Command, left, and Contrast control bar, right. Depth Cursor The depth cursor consists of a horizontal line with a digital depth box on the right side. The numbers inside the box show the depth of the cursor. Cursor line Depth box At left, Sonar Page menu with Depth Cursor command selected. At right, sonar chart with the depth cursor active. The line indicates the large fish is 40.52 feet deep. The cursor can be moved to any location on the screen, letting you pinpoint the depth of a target. 1.
Depth Range - Automatic When turned on for the first time, the bottom signal is automatically placed in the lower half of the screen. This is called Auto Ranging and is part of the automatic function. However, depending upon the bottom depth and the current range, you can change the range to a different depth. To do this: 1. From the Sonar Page, press MENU|↓ to DEPTH RANGE|ENT. At left, Sonar Page menu with Depth Range command selected. At right, the Depth Range Control Scale. 2.
NOTE: The sonar's depth capability depends on the transducer installation, water and bottom conditions, and other factors. Depth Range - Upper and Lower Limits Virtually any segment of the water column can be displayed by using the upper and lower limit feature. This lets you pick the shallow and deep depth range limits that are shown on the screen, provided there is at least 5 feet between the upper and lower limit you select. For example, a range from 12 feet to 34 feet could be used.
Area "zoomed" Normal display, in auto depth range mode, left. At right, display "zoomed" with Upper and Lower Limits focusing on the portion of the water column from 10 feet to 20 feet deep. 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.
Fish I.D. (Fish Symbols & Depths) The Fish I.D. feature identifies targets that meet certain conditions as fish. The microcomputer analyzes all echoes and eliminates surface clutter, thermoclines, and other signals that are undesirable. In most instances, remaining targets are fish. The Fish I.D. feature displays fish symbols on the screen in place of the actual fish echoes. There are several fish symbol sizes. These are used to designate the relative size between targets. In other words, Fish I.D.
To turn the Fish I.D. feature on: 1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT. 2. Press ↓ to FISH ID SYMBOLS|ENT|EXIT|EXIT. To turn off Fish I.D., repeat these instructions. FishTrack The FishTrack feature shows the depth of a fish symbol when it appears on the display. This lets you accurately gauge the depth of targets. This feature is available only when the Fish I.D. feature is on. The default setting for FishTrack is off.
Overlay Data To change the digital data shown on top of the sonar page: 1. Press MENU|↓ to OVERLAY DATA|ENT. 2. Press ↓ or ↑ to select Data Type|ENT. Overlay Data command on the Sonar Menu, at left.

Press ↓ or ↑ to select Data Type, then press Ent. The DATA SIZE (displayed in the bottom of the Overlay Data Shown window) cycles through available sizes. Keep pressing Ent until it shows the desired Data Size, then press EXIT. The selected data type will be displayed in the new size.
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. When you change the Ping Speed to any setting greater than 50 percent, the unit automatically enters HyperScroll mode.
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. The Ping Speed Control Bar appears. Press ↓ to decrease ping speed to 50 percent. When it's set at the desired level, press EXIT.
Reset Options This command is used to reset all features, options and settings to their original factory defaults. This is useful when you have changed several settings and want to return the unit to basic automatic operation. 1. Press MENU|MENU|↓ to RESET OPTIONS|ENT. 2. Press ↑ or ↓ to YES|ENT. 3. All the menus are cleared and all options are returned to the factory settings. Main Menu with Reset Options command selected.
High sensitivity levels let you see this detail, but it can also clutter the screen with many undesired signals. Typically, the best sensitivity level shows a good solid bottom signal with Colorline and some surface clutter. Automatic Sensitivity The default sensitivity mode is automatic. The unit bases the sensitivity level on water depth and conditions. When the unit is in the automatic mode, sensitivity is automatically adjusted to keep a solid bottom signal displayed, plus a little more power.
At left, Sonar Menu with Sensitivity command selected. At right, the Sensitivity Control Bar. To adjust sensitivity in manual mode: 1. First, turn off Auto Sensitivity: from the Sonar Page, press MENU|↓ to AUTO SENSITIVITY|ENT. 2. Press ↑ to SENSITIVITY|ENT and the Sensitivity Control Bar appears. Press ↓ or ↑ to pick a different sensitivity setting. When it's set at the desired level, press EXIT. To turn Auto Sensitivity back on: From the Sonar Page, press MENU|↓ to AUTO SENSITIVITY|ENT|EXIT.
On sailboats or other large vessels with deep drafts, the distance between the transducer installation and the keel or lower engine unit can be several feet. In those cases, an inexact depth reading could result in grounding or striking underwater structure. The Keel Offset feature eliminates the need for the navigator to mentally calculate how much water is under his keel.
1. Press MENU|MENU|↓ to SET LANGUAGE|ENT. 2. Use ↓ or ↑ to select a different language and press ENT. All menus now appear in the language you selected. Software Version Information From time to time, Lowrance updates the operating system software in some of its products. These software upgrades are usually offered to customers as free downloads from our web site, www.lowrance.com. These upgrades make the unit perform better or introduce a new feature or function.
Sonar Page & Sonar Chart Display Options The X67C offers four chart display options. To cycle through them, press EXIT to clear any menus, then press ENT repeatedly until the desired mode appears.

Notes 67
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.
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. It may change the range to limits far greater than the water you are in.
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. 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.
