    NOTICE! The storage temperature for your unit is from -4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended storage in temperatures higher or lower than specified will damage the liquid crystal display in your unit. This type of damage is not covered by the warranty.

    Depending on your sonar unit's connectors, your transducer cable may also have the sonar unit's power cable attached to it. If that is the case, be sure to install the transducer first, before connecting the power cable to a power source. See the instructions later in this manual for connect- ing the power cable to a battery or other power supply.
  • Page 8 NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds faster than 35 mph. Typically, a good transom location on aluminum boats is between the ribs closest to the engine.

  • Page 9: How Low Should You Go

    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. This will usually give you the best combination of smooth water flow and protec- tion from bangs and bumps.

    varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish arches. This can be a problem on hulls that sit with the bow high when at rest or at slow trolling speeds.
  • Page 11 Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's pa- rallel with the ground. If you can, then go to step 3. If it doesn't, repeat step 2, but use a different alignment letter.

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.

A successful 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. See the figure below. WARNING: Do not remove any material from your inner hull unless you know the hull's composition.

  • Page 17: Testing Determines Best Location

    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. 1. Anchor the boat in about 30 feet of water. Add a little water to the sump of the boat.

    hull. This is especially true if you have to turn sensitivity all the way up to get a decent bottom signal. 4. Most people can get good results by following steps 1 through 3, so this step is optional. If you want to make an extra effort to be absolutely sure that your selected location will work under all conditions, make a test run with the boat on plane and observe the bottom signal.

    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.

Attach the unit to the bracket by first connecting the power/transducer and accessory cables. Then, hold the sonar unit vertically and slide it onto the bracket from above.

  • Page 23: Portable Sonar Installation

    Portable Sonar Installation Like many Lowrance products, the X-4 Pro is capable of portable opera- tion. It uses the optional PPP-12 portable power pack. The power pack and portable transducers expand the uses for your sonar.

  • Page 24: Installing The Batteries

    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 Open the case and lay it flat. (The latch is located below the handle.) Insert eight "AA" size batteries into the battery adapter and place it in the battery compartment.
