5 display, where an image of the object appears on the scrolling sonar chart. The sonar's microprocessor calculates the time lapse between the transmitted signal and echo return to determine the distance to the object. The whole process repeats itself several times each second.
6 WAAS work together to get you where you're going. The Global Positioning System (GPS) was launched July 17, 1995 by the United States Department of Defense. It was designed as a 24- hour-a-day, 365-days-a-year, all weather global navigation system for the armed forces of the U.
7 Like most GPS receivers, this unit doesn’t have a compass or any other navigation aid built inside. It relies solely on the signals from the sat- ellites to calculate a position. Speed, direction of travel, and distance are all calculated from position information.
8 menu command to use by finding the boldface command text. The fol- lowing paragraphs explain how to interpret the text formatting for those commands and other instructions: Arrow Keys The arrow keys control the movement of dotted cross-hair lines on your mapping screen called the cursor.
9 Section 2: 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.
10 Remember, the transducer location and 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 5/8" drill bit.
11 boat hulls have a flat keel pad that offers a good mounting surface. On vee hulls, try to place the transducer where the deadrise is 10 ° or less. Left, vee pad hull; right, vee hull. A pod style transducer is shown here, but the principle is the same for Skimmers inside a hull.
12 Align transducer centerline with hull bottom. 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.
13 Second, the transducer angle cannot be adjusted for the best fish arches on your sonar display. (This is not an issue for flasher-style sonars.) Lack of angle adjustment can be particularly troublesome on hulls that sit with the bow high when at rest or at slow trolling speeds.
14 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.
15 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.
16 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 tra nsd uce r. If possible, route the transducer cable away from other wiring on the boat.
17 3. Route the transducer cable alongside the trolling motor shaft. Use plastic ties (not included) to attach the transducer cable to the troll- ing 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 trans- ducer is ready for use.
18 If the arch slopes up – but not back down – then the front of the trans- ducer 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 re- move any oil film.
19 Testing Determines Best Location Ideally, the shoot-thru transducer should be installed as close to the transom as possible, close to the centerline. This will give you the best performance during high speed maneuvers. Shoot-thru-hull transducer locations for high speed or trolling speed operation.
20 2. Next, take the transducer out of the water and place it in the water in the sump of the boat, face down. (The transducer face is shown in the figure on the following page.) Notice how the signal strength de- creases. The second bottom signal will probably disappear and the bot- tom signal intensity will likely decrease.
21 Epoxy transducer to hull. WARNING: Use only the epoxy available from LEI. It has been for- mulated to work with these installation procedures. Other epoxy types may be too thin or may not cure to the right consistency for optimum transducer performance.
22 5. After the epoxy has cured, route the cable to the sonar unit and it's ready to use. POWER AND CABLE CONNECTIONS The unit works from a 12-volt battery system.
23 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.
24 In-dash mounting template for M68. NOTE: This figure is not printed to scale. Bracket Installation Mount the unit in any convenient location, provided there is clearance 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/transducer cable.
25 Front view (left) and side view (right) showing dimensions of the M68 when mounted on quick release bracket. If you wish, you can fill in the hole around the cable with a good marine sealant compound. (Some marine dealers stock cable hole covers to con- ceal the opening.
26 M68 quick release mounting bracket. Slots in the base allow routing the cable from beneath the mount. Attach the unit to the bracket by first connecting the power/transducer cable. Then, hold the sonar unit vertically and slide it onto the bracket from above.
27 Adjust viewing angle: use one hand to press and release the spring- loaded ratchets while you move the unit with the other hand. An op- tional GBSA-3 swivel base is shown with the quick release bracket. Portable Sonar Installation Like many Lowrance products, the M68 sonar is capable of portable operation.
28 NOTE: When the unit is not in use, we recommend you unplug the power connector to reduce the possibility of corrosion or battery drain. When you store the unit, always remove the batteries because dead batteries can leak and corrode the contacts.
29 If the batteries do lose a charge, you can sometimes restore them by placing them in a warm room or car interior. A better way is to replace them with batteries that have been kept warm. WARNING: Never heat the batteries over an open flame or direct hot air onto them.
30 Portable transducer installed on boat transom. NOTE: For optimum operation, the portable transducer should be adjusted so that it is parallel to the ground. For more information on this, see the earlier segment on Transducer Orientation and Fish Arches.
31 Section 3: 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 ex- planations below: Lowrance M68 Sonar, front view, showing screen and keyboard.
32 4. ARROW KEYS – These keys are used to navigate through the menus, make menu selections, move the plotter cursor and sonar chart cursor and enter data. 5. ENT (Enter) – This key allows you to save data, accept values or execute menu commands. It is also used to create event marker icons.
33 Main Menu. The Main Menu commands and their functions are: Screen command: changes the contrast or brightness of the display screen. Sounds command: enables or disables the sounds for key strokes and alarms and sets the alarm style. Alarms command: turns GPS alarms on or off and changes alarm thresholds.

42 Notes.
43 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.
44 3. Press ↓ or ↑ to select a setting, then press ENT . 4. To return to the previous page, press EXIT | EXIT . Alarms This unit has three 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.
45 3. Press ↑ or ↓ until the depth is correct, then press ENT . 4. Press ← to S HALLOW A LARM E NABLED | ENT | EXIT . 5. To turn off the alarm, press MENU | MENU | ↓ to A LARMS | ENT | ↓ to S ONAR A LARMS | ENT | ENT | EXIT . To switch to a different depth setting, open the Sonar Alarms menu and repeat the instructions in step 3 above.
46 3. To set the upper boundary for the Zone Alarm, use ← or → to select U PPER , then press ↑ or ↓ to move the top of the bar to the desired depth. 4. To set the lower boundary for the Zone Alarm, use ← or → to select L OWER , then press ↑ or ↓ to move the bottom of the bar to the desired depth.
47 Chart Speed The rate that echoes scroll across the screen is called the chart speed. The default is maximum; we recommend that you leave the speed set there for virtually all fishing conditions. However, you might consider experimenting with chart speed when you are stationary or drifting very slowly.
48 they show up mostly as blue arches. A hard bottom or other relatively hard target returns a strong signal which causes a wider brightly col- ored line (reddish yellow to bright yellow.) If you have two signals of equal size, one with red to yellow color and the other without, then the target with brighter color (yellow) is the stronger signal.
49 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. At left, Sonar Page menu with Depth Cursor command selected. At right, sonar chart with the depth cursor active.
50 At left, Sonar Page menu with Depth Range command selected. At right, the Depth Range Control Scale. 2. The Depth Range Control Scale appears. Press ↑ or ↓ to select a dif- ferent depth range. A dark bar highlights the selected range. Range numbers in gray cannot be selected.
51 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.
52 To turn off upper and lower limits: 1. From the Sonar Page, press MENU | ↓ to A UTO D EPTH R ANGE | 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 con- tinues to operate normally.
53 You may see fish symbols on the screen when actually, there are no fish. The reverse is also true. 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.
54 Sonar Features menu with Fish I.D. Depths selected. When the che ck box to t he l eft is c hec ked , th e fe atu re i s on . At right, Sonar Page show- ing Fish I.D. symbols and FishTrack depths turned on. HyperScroll See the entry on Ping Speed, which controls the HyperScroll feature.
55 Data list showing "Ground Speed" turned on to display on Sonar Page. 3. To return to the previous page, press EXIT | EXIT . To turn off displayed data: 1. Press MENU | ↓ to O VERLAY D ATA | ENT . 2. Press ↓ or ↑ to select Data Type, then press ENT until the check mark to the left of the selected data type disappears.
56 Ping Speed & HyperScroll Ping Speed controls the rate at which the transmitter and transducer broadcast sonar sound waves — pings — into the water.
57 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.
58 Sensitivity & Auto Sensitivity The sensitivity controls the ability of the unit to pick up echoes. Sensi- tivity can be adjusted, because water conditions vary greatly. A low sensitivity level (from zero to 50 percent) excludes much of the bottom information, fish signals, and other target information.
59 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 A UTO S ENSITIVITY | ENT . 2. Press ↑ to S ENSITIVITY | ENT and the Sensitivity Control Bar appears.
60 On sailboats or other large vessels with deep drafts, the distance be- tween 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.
61 2. Press ↓ to S ONAR C HART M ODE | ENT . 3. Press ↓ or ↑ to Mode Name | ENT . 4. Press EXIT | EXIT to return to the Sonar Page. Sonar Page & Sonar Chart Display Options The M68 offers four Sonar chart display options.
62 Split Zoom Sonar Chart. Image at left shows the left window zoomed to 2X. The right image shows the left window zoomed to 4X. The depth overlay data is set to the default large text size; the water temperature is set to the medium text size.
63 Flasher page. Sonar Simulator This unit has a built-in simulator that lets you run it as if you were on the water. All sonar features and functions are useable. When in simulator mode, you will see [Simulator Mode] in the Sonar Page title bar. To use the simulator: 1.
64 To turn on sonar and start the chart scrolling again, repeat the above step. Sonar Menu with Stop Chart command selected. The box is unchecked, indicating that the chart is scrolling across the screen. Surface Clarity The markings extending downward from the zero line on the chart are called "surface clutter.
65 2. Press ↓ or ↑ to select clarity level | EXIT | EXIT | EXIT . Upper and Lower Limits See the entry in this section for Depth Range - Upper and Lower Limits Zoom & Zoom Bar "Zooming" the display is used to enlarge small detail, fish signals and the bottom with its associated structure.
66 lets you rapidly move the zoomed area up and down to different depths. By "pointing" your zoom at different portions of the chart as it scrolls, you can get a good, close-up look at structure or cover below you. To use Zoom Pan, switch to a manual depth Range setting (see page 50) and turn on 2X or 4X Zoom.
67 Section 5: Ice Fishing The M68C and the M68C IceMachine work exactly alike. Each M68C unit contains a menu command that allows you to switch the sonar in and out of IceMachine mode. The only differences between the two pack- ages are the accessories they are shipped with.
68 there is the Ice Flasher. This page is only visible in IceMachine Mode. You can tell at a glance which mode you are in because the battery gauge only appears in the lower right corner of the Ice Flasher page. Ice Flasher page, left, and normal Flasher page, right.
69 At left, M68C IceMachine opening screen, showing the Full Sonar Chart Page. The Backlight Level control bar automatically disappears after five seconds. At right, the Full Sonar Chart is shown. To enter the IceMachine mode: 1. From the Full Chart Sonar page, press ENT | ENT | ENT to switch to the normal Flasher page.
70 The following figure shows the various components of the Ice Flasher page display. Ice Flasher page. Temp display requires optional TS-2U temp sensor.
71 To adjust sensitivity: 1. Start with your IceMachine showing the Ice Flasher page, in the de- fault IceView color mode. 2. Drop your lure five to 10 feet directly below the transducer. You should be able to follow the fall of the bait on the flasher screen.
72 In the Ice Flasher, the weakest signals are shown in black and the strongest signals show as red. Fish are among the weakest echoes, so they show up mostly as black and blue bands on the flasher screen. The hardest surfaces, like the bottom, show as red.
73 Red signals are much larger fish, or fish that are in the center of the sonar cone, almost directly below the transducer. They return the strongest echoes. Signals that are yellow and some other color result from mid-sized fish that are in a transition zone between the center and outer edges of the sonar cone.
74 At left, Flasher Page Menu with Flasher Options command high- lighted. Center, Flasher Options Menu with Flasher Display Mode se- lected. At right, the Split Zoom option has been selected. The following figure show the bottom target separation possible using the flasher's Split Zoom.
75 There are six color mode options for the flasher pages, and seven for the sonar chart page. The Ice Flasher default color is the IceView mode, but other settings may suit your eyes better.
76 Another variation used by some anglers requires a small plastic bag, such as a food storage bag. They fill the bag with a mixture of RV anti- freeze and water. The bag is placed on the ice surface, and the trans- ducer is rested in the "puddle" just as your head rests on a pillow.
77 Section 6: 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.
78 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.
79 To eliminate or minimize the effects of electrical noise, first try to de- termine 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.
80 Notes.
81 Section 7: Basic GPS Operations This section addresses the unit's most basic GPS operations. The tuto- rials presented in Sec. 7 follow a chronological order. Sec. 8, Advanced GPS Operations , will discuss other more advanced functions and utili- ties.
82 4. ARROW KEYS – These keys are used to navigate through the menus, make menu selections, move the map cursor and sonar chart cursor and enter data. 5. ENT (Enter) – This key allows you to save data, accept values or execute menu commands. It is also used to create event marker icons.
83 You can access the Main Menu from any of the display options by pressing MENU | MENU . To clear the menu screen and return to the page display, press EXIT . Main Menu. The Main Menu commands and their functions are: Screen command: changes the contrast or brightness of the display screen.
84 Pages The unit has two Pages that represent the two major operating modes. They are the Map Page and the Sonar Page. Each Page has several sub- set display options. They are accessed by pressing the PAGES key, then using → or ← to select a Page, then ↑ or ↓ to select a display option.
85 Satellite Page. Left view indicates unit has not locked on to any satel- lites and does not have a fix on its position. Center view shows satel- lites being scanned. Right view shows satellite lock-on with a 3D posi- tion acquired (latitude, longitude and altitude.
86 Navigation Page This screen has a compass rose that not only shows your direction of travel, but also the direction to a selected waypoint. To get to the Navi- gation Page: Pre ss PAGES | ← to M AP | ↑ or ↓ to N AVIGATION | EXIT .
87 Speed (ground speed) is the velocity you are making over the ground. (If you wish, you can customize the Speed window to display Closing Speed instead. Closing Speed is also known as velocity made good. It's the speed that you're making toward the waypoint.
88 A circular symbol depicting your destination (waypoint) appears on the screen as you approach the waypoint, as shown on the screen in the previous figure. Travel Time is the time that it will take to reach your destination at your present closing speed.
89 Far left, Map Page opening screen. Center, zoomed to 100 miles and right, zoomed to 15 miles. The maximum zoom range for showing additional map detail is 20 miles. You can continue to zoom in closer, but the map will simply be enlarged without revealing more map content (except for a few major city streets).
90 Pages Menu with Map With Sonar option selected, left. Map With Sonar display, at right. The left map is active. Resize Window is another extremely handy feature for pages that have two major windows. You can change the horizontal size of the windows to suit your viewing preference.
91 GPS Quick Reference Start outdoors, with a clear view of the open sky. As you practice, try navigating to a location at least a few blocks away. While you're learning, navigation in too small an area will constantly trigger arrival alarms. 1. Install the unit.
92 Find Your Current Position Finding your current position is as simple as turning the unit on. Un- der clear sky conditions, the unit automatically searches for satellites and calculates its position in approximately one minute or less. NOTE: "Clear sky" means open sky, unobstructed by terrain, dense foliage or structures.
93 The selected wreck (the Empress) to the southeast is 12.81 miles away. Selecting Any Map Item With the Cursor 1. Use the zoom keys and the arrow keys to move around the map and find the item you wish to select. 2. Use the arrow keys and center the cursor cross-hair on the desired ob- ject.
94 Sequence for setting a waypoint. Step 1: while traveling, quickly press WPT twice to call up Find Waypoint screen (seen in Step 2) and set a point. Step 3: a message says the waypoint has been saved. Step 4: ve- hicle continues on its way; number waypoint symbol is visible on map.
95 2. Press WPT | WPT . The waypoint is saved and automatically given a name with a sequential number, such as "waypoint 001." The waypoint symbol and number appear on the map. Create Waypoint by Entering a Position 1. Press WPT | → to N EW | ENT .
96 Navigation Page, navigating toward waypoint 2 and leaving a trail. Set Man Overboard (MOB) Waypoint One of boating's most terrifying events is having a friend or family member fall overboard. This situation can be deadly on any body of wa- ter — fresh or salt.
97 Navigating to Man Overboard: "Man Overboard activated" message shown at left. The Navigation Page is shown in the center and Map Page is shown at right. The victim is astern of the vessel; the GPS shows which direction to steer to for the rescue.
98 Navigate to cursor. In this example, the cursor has selected the town of Oologah, Oklahoma. 3. Press MENU | ENT and the M68 will begin navigating to the cursor location. The Map Page will display a red line from your current position to the cur- sor position.
99 Navigate to a Map Place For map places that are in view on the map, you can easily use the Navigate to Cursor command above; just use the cursor to select the map place. The other method involves searching for map places with the Find Waypoint command, launched with the WPT key.
100 Sequence for saving a trail and beginning a new one. At left, My Trails command. Center, the Trails Menu. The arrow to the right of Trail 3 indicates the trail is "active," and the check to the left indicates the trail is visible on the map display.
101 You can save and recall up to 10 different plot trails. Tip: Another quick way to stop recording one trail and begin a new one is to use the New Trail command: Press MENU | MENU | ↓ to M Y T RAILS | ENT | ENT | EXIT | EXIT | EXIT . Caution: You also have the option of completely turning off trail record- ing, under the trail Options command.
102 The other two methods provide a full range of navigation data and work with both the Map Page and Navigation Page. The only difference be- tween them is "navigating a trail" follows a trail forward (from start to end) while "backtracking" follows a trail in reverse (from end to start.
103 Navigate a trail menu sequence: Fig. 1, My Trails command. Fig. 2, Trails Menu. Fig. 3, Edit Trail Menu. Fig. 4, Edit Route Menu with Navigate Route command highlighted for Trail 1. A trail is always con- verted to a "route" when you navigate the trail.
