    320C has several powerful features you can control by scrolling through easy-to-use menus with the arrow and menu keys. To get started with your Eagle sonar, first read the installation section. It contains instructions for mounting the sonar unit, the transducer and any optional accessories, such as a speed sensor.

    Instructions = Menu Sequences Most functions you perform with the sonar unit are described as a se- quence of key strokes and selecting menu commands. We've written them in a condensed manner for quick and easy reading. For example, instructions for turning on the Fish ID feature would look like this: 1.

    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 vehicle or vessel! 1.

    vent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up," the bracket can easily be pushed back into place without tools. Read these instructions carefully before attempting the installation. Determine which of the installation methods is right for your boat. Remember, the transducer location and installation is the most critical part of a sonar installation.

  • Page 15: Selecting A Transducer Location

    Selecting a Transducer Location 1. The location must be in the water at all times, at all operating speeds. 2. The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving.

    be displayed on the sonar's screen. Use caution when routing the trans- ducer cable around these wires. CAUTION: Clamp the trans- ducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed.

  • Page 17: Shoot-thru-hull Vs. Transom Mounting

    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.

  • Page 18: Transom Transducer Assembly And Mounting

    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. Fourth, if your Skimmer transducer has a built in temp sensor, it will only show the temperature of the bilge, not the water surface temp.

    from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the "A" position is correct for your hull. If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket.

  • Page 20

    Assemble transducer and bracket. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The transducer's centerline should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Mark the center of each slot for the mounting screw pilot holes.

    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. Side view shown at left and seen from above at right.

Electrical noise from the engine's wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires. WARNING: Clamp the transducer cable to the transom close to the transducer.

    Transducer aimed too far back Full fish arch Transducer angles and their effects on fish arches. 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 25: Shoot-thru-hull Preparation

    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 through solid fiberglass. 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.

  • Page 26: 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.

    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 package and place them on the paper plate.

  • Page 30: Speed/temperature Sensors

    Speed/Temperature Sensors The FishEasy 320C can accept as many as two temperature sensors, which can be used to monitor the temperature of surface water, a live well or some other location. These units can accept an optional speed sensor for showing speed and distance traveled. However, you can only use one accessory at a time.

  • Page 35: Power Connections

    If the base of the transom has a radius, fill the gap between the tran- som and the sensor with the caulking compound. This will help ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 5/8".

    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 manual.

    Weak bottom echo, digital readings erratic, or no fish signals: 1. Make sure the transducer is pointing straight down. Clean the face of the transducer. Oil, dirt and fuel can cause a film to form on the trans- ducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull.
