    Section 1: Read Me First! How this manual can get you out on the water, fast! Welcome to the exciting world of digital sonar! We know you're anxious to begin finding fish, but we have a favor to ask. Before you grab your unit and begin installing it, please give us a moment or two to explain how our manual can help you get the best performance from your com- pact, wide-screen, fish finder.

    X107CDF. It has 35°/12° cone angles. A single-frequency with built-in temperature sensor is packed with the X102C. It has a 20° cone angle. Transducers operate at speeds up to 70 mph (61 kts).

  • Page 7: How Sonar Works

    In simple terms, here's how it finds the bottom, or the fish: 4,000 watts peak-to-peak/500 watts RMS. X102C: 2,400 watts peak-to-peak/300 watts RMS. X102C: 800 feet (244 meters). Actual capability depends on transducer con- figuration and installation, bottom composi- tion and water conditions. All sonar units typically read deeper in fresh water than in salt water.

  • Page 8: How To Use This Manual: Typographical Conventions

    The transmitter emits an electrical impulse, which the transducer con- verts into a sound wave and sends into the water. (The sound frequency can't be heard by humans or fish.) The sound wave strikes an object (fish, structure, bottom) and bounces back to the transducer, which converts the sound back into an electrical signal.

    Installation & Accessories 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 drill- ing any holes in your vessel! 1.

    NOTE: The following installation types also call for these recommended tools and required supplies that you must provide (supplies listed here are not included): Single-frequency transom installations Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flat- head screwdriver. Supplies: high quality, marine grade above- or below- waterline sealant/adhesive compound.

    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.

  • Page 14: Shoot-Thru-Hull Vs. Transom Mounting

    Transducer centerline 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 coming out of the water as you cross waves or wakes.

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. Those hulls require either a transom mount or a thru-hull installation.

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.
  • Page 23 WARNING: Do not remove any material from your inner hull unless you know the hull's composition. Careless grinding or cutting on your hull can result in damage that could sink your boat. Contact your boat dealer or manufacturer to confirm your hull specifications. Fill with resin Flotation material Epoxy to hull first...
  • Page 24 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 unit, turn it on, then hold the transducer over the side of the boat in the water.
  • Page 25 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.

  • Page 33 Front Install the gimbal bracket. Orient the bracket so the arms slope toward Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer cables. The best location for this hole is immediately under the gimbal bracket location. This way, the bracket can be installed so that it covers the hole, holds the cables in position and results in a neat installation.
  • Page 34 After drilling the hole, pass the transducer connector up through the hole from under the dash. Pass the power cable's bare-wire end down though the hole from the top. If you wish, you can fill in the hole around the cables with a good ma- rine caulking compound.

  • Page 35: Face Cover

    Portable Installation Like many Lowrance products, the unit is capable of portable operation by using an optional portable power pack. The power pack, a magnet- equipped antenna module and an optional portable transducer, expands the uses for your sonar/GPS unit. It makes it easy to transfer your unit from a boat to a car, recreational vehicle, airplane or other vehicle without mounting a second bracket.

  • Page 46 You can change the sensitivity level whether you are in Auto Sensitiv- ity 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 ad- justing a car's speed with the accelerator pedal while cruise control is on.

    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.

  • Page 57: Depth Range - Upper And Lower Limits

    NOTE: The sonar's depth capability depends on water and bottom condi- tions, transducer installation 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 deep and shallow depth limits that are shown on the screen, provided there is at least 10 feet between the upper and lower limits you select.

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 change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity.
