4 WARNING! A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION When showing navigation data to a position (waypoint), a GPS unit will show the shortest, most direct path to the waypoi nt. It provides navigation data to the waypoint regardless of obstructions. Th erefore, the prudent navigator will not only ta[...]

7 Section 2: Installation & Accessories Preparations You can install the sonar and GPS sy stems 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/[...]

8 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 mus[...]

9 3. The transducer should be installed with its face pointing straight down, if possible. For shoot-thru applications: Many popular fishing boat hulls have a flat keel pad that offers a good mounting surface. On vee hulls, try to place the transd ucer where the deadrise is 10 ° or less. Left, vee pad hull; right, vee hull. A pod style transducer [...]

10 Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slot s in the mounting brackets allow you to loosen the screws and slide the tr ansducer up or down.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be com[...]

11 Second, the transducer angle cannot be adjusted for the best fish arches on your sonar display. (Thi s 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. Tho[...]

12 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[...]

13 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[...]

14 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 tr an sd uc e 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, an d aerators can be picked up by the [...]

15 3. Route the transducer cable alon gside 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 ORIENTATION AND FISH ARCHES[...]

16 SHOOT-THRU-HULL PREPARATION Hulls With Floatation Materials The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass lay- ers. The sonar signal must pass th rough solid fiberglass. A successful transducer installation can be made on hulls with flotation materials [...]

17 Shoot-thru-hull transducer locations for high speed or trolling speed operation. To choose the proper location for shoot-thru-hull mounting, follow these testing procedures: (You may need a helper to complete these steps.) 1. Anchor the boat in about 30 feet of water. Add a little water to the sump of the boat. Plug the transducer into the sonar[...]

18 3. Now move the transducer around to find the best location with the strongest possible bottom signal. If yo u find a spot with an acceptable bottom signal, mark the location and move on to step 4. If you can't get an acceptable bottom signal, try turning up the sensitiv- ity by three or five keystrokes an d then move the transducer around [...]

19 2. The epoxy consists of the epoxy itself and a hardener. Remove the two compounds from the package and place them on the paper plate. Thoroughly stir the two compounds together until the mixture has a uniform color and consistency. Do not mix too fast or bubbles will form in the epoxy. After mixing, yo u have 20 minutes to complete the installa[...]

20 with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery. CAUTION: When using the unit in a saltwater environment, we strongly rec- ommend that you shut off the power supply to the power cable when the unit is not in use. When the unit is turned off but still connected to a power sup[...]

21 WARNING: This product must be independently fused with the en- closed 3-amp fuse (or equivalent), even if you connect to a fused accessory or power buss. If a malfunction happens inside the unit, extensive dam- age can occur if the enclosed fu se is not used. As with all electrical devices, this unit could be damaged to a point that it is unrepa[...]

22 In-dash mounting template for M52 Pro. NOTE: This figure is not printed to scale.

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

24 M52 Pro 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 i[...]

25 Portable Sonar Installation Like many Lowrance products, the M52 Pro sonar is capable of portable operation. It uses the optio nal PPP-12 portable power pack. The power pack and portable transducers expand the uses for your so- nar. An alternative to the PPP-12 is the PPP-15 portable power pack, which was designed especially for ice fishing. It [...]

26 Portable transducer assembly: rear vi ew (left) and side view (right.) Clean the chosen area of the hull be fore attaching the suction cup. Lo- cate 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. [...]
