2. Setup and Installation

Proper installation is crucial for optimal performance of your Humminbird 717. It is recommended to review the full installation guide provided with your product for detailed instructions.

2.1 Mounting the Control Head

Select a location on your boat that provides clear visibility of the display and easy access to the controls. The mounting surface should be flat and sturdy. Use the provided mounting bracket and hardware to secure the control head. Ensure the unit is positioned to avoid direct sunlight glare and spray.

2.2 Transducer Installation

The transducer is responsible for sending and receiving sonar signals. It must be installed in a location that provides an unobstructed view of the water beneath the boat. Common installation methods include transom mount, in-hull, or trolling motor mount. Ensure the transducer cable is routed away from electrical interference and secured to prevent damage.

2.3 Power Connection

Connect the power cable to a 12V DC power source. It is recommended to connect directly to the boat's battery or a dedicated fuse panel. Ensure the connection is secure and protected from moisture. An in-line fuse should be installed on the positive wire to protect the unit from power surges.

3. Operating Instructions

The Humminbird 717 is designed for intuitive operation. Familiarize yourself with the control buttons and display features to maximize its utility.

3.1 Powering On/Off

Press the Power button (labeled with a circle and vertical line) located on the right side of the unit to turn the device on. Press and hold the Power button for a few seconds to turn it off.

3.2 Understanding the Display

The 5-inch grayscale display provides real-time sonar readings.

• Depth Reading: Typically displayed prominently, indicating the current water depth.
• Water Temperature: Shows the current water temperature.
• Boat Speed: Displays the boat's speed (if speed sensor is connected).
• Sonar Graph: The main area showing fish arches, bottom contours, and structure. Darker shades indicate stronger returns.
• Depth Scale: Vertical scale on the right side of the sonar graph indicating depth in feet.

3.3 Control Buttons

• VIEW: Cycles through different display views (e.g., full screen sonar, split screen).
• MENU: Accesses the main menu for adjusting settings such as sensitivity, depth range, chart speed, and feature settings. Press multiple times to navigate through menu layers.
• EXIT: Exits the current menu or returns to the previous screen.
• Arrow Keys (Up/Down/Left/Right): Used for navigating menus, adjusting settings, and zooming in/out on the sonar screen.

3.4 Sonar Operation (DualBeam PLUS)

The DualBeam PLUS sonar utilizes two beams:

• 20-degree Narrow Beam: Provides detailed bottom structure and fish arches directly beneath the boat.
• 60-degree Wide Beam: Offers a broader coverage area, ideal for locating fish over a larger region.

You can select to view either beam individually or combine them for a comprehensive view. Adjusting sensitivity and depth range through the MENU will optimize sonar performance for different water conditions and depths.

4. Maintenance

4.1 Cleaning the Unit

Regularly clean the display screen and unit housing with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the screen and plastic components. For stubborn stains, a mild soap solution can be used, followed by rinsing with fresh water.

4.2 Transducer Care

Inspect the transducer periodically for marine growth or damage. Clean the transducer face with a soft brush and mild soap to ensure optimal sonar performance. Avoid scraping the transducer face with sharp objects.

4.3 Storage

When not in use for extended periods, store the Humminbird 717 in a dry, cool environment, away from direct sunlight and extreme temperatures. Disconnect the power cable to prevent battery drain.
