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. How Your GPS Works You'll navigate faster and easier if you u[...]

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.S. and its allies. Civilian use was also avail- able at first, bu[...]

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. Therefore, in order for the unit to determine direction of travel, you must be m[...]

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. The arrow keys also control a hori- zontal line depth curso[...]

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. Determine the approximate location for the sonar/G[...]

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. NOTE: The following installation types also call for these recommended tools and required supplies that you mu[...]

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. 4. If the transducer is mounted on the transom, make sure it doesn[...]

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.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be comin[...]

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. Third, a transducer CAN NOT shoot through wood and metal hulls. Thos[...]

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. Insert bolt and che[...]

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. Route cable over bolt and through bracket. Si[...]

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. Electrical noise from the engine's wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the son[...]

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. Transducer mounted on trolling motor, s[...]

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. Oil a[...]

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. To choose the proper location for shoot-thru-hu[...]

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. 3. Now move the transd[...]

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. 2. The epoxy consists of the epoxy itself and a hardener. Remove the two compounds from the p[...]

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. For the best results, at- tach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical i[...]

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. This will protect both the unit and the power cable in t[...]

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. (See the following drawings, [...]

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.) This unit uses a quick release mounting bracket. When you run the ca- ble [...]

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. (The back of the unit should be touching the front of the bracket as you lower it into [...]

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. It uses the optional PPP-12 portable po[...]

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. After installing the batteries, plug the cable's power connector into the socket on the battery[...]

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. A fire or explosion could result. Portable Transducer Assembly Recommended too[...]

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. Cover in the form of weed beds or submerged timber display in the blue to yellow range. Batt[...]

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. They represent medium-strong echoes[...]

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.

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. For example, some of our fishing friends favor the striking green-on- black contrast of the Nightview mode…they use it a lot, even in broad daylight! Experi[...]

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. For contact information, refer to the last page, just inside the back cover of this[...]

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. If this hap- pens, place the unit in the manual mode, then c[...]

79 To eliminate or minimize the effects of electrical noise, first try to de- termine the cause.
