Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your Lowrance Elite-5 Ti Fishfinder Chartplotter. Please read these instructions thoroughly before using the device to ensure optimal performance and longevity. The Elite-5 Ti is a versatile marine electronic device combining a fishfinder with CHIRP Sonar and Downscan Imaging, and a chartplotter with built-in GPS.
Setup
1. Mounting the Unit
The Elite-5 Ti unit is designed for surface mounting. Select a location on your vessel that provides clear visibility, easy access to controls, and protection from excessive moisture or direct impact. Ensure sufficient space for cable routing and unit rotation if applicable.
2. Power Connection
Connect the power cable to a 12-volt DC power source. It is critical to provide a stable 12V supply for correct operation. Insufficient voltage, such as 11.4 volts or lower, can lead to display malfunctions or prevent the unit from powering on correctly. Use appropriate gauge wiring and ensure all connections are secure and corrosion-free.
3. Transducer Installation
Install the Downscan Transducer according to the instructions provided with the transducer kit. Proper transducer placement is crucial for accurate sonar readings. Avoid locations with turbulent water flow or obstructions that could interfere with the sonar signal.
Operating Instructions
1. Power On/Off
Press and hold the power button (labeled with a circle and vertical line) located on the right side of the unit to turn the device on or off. A brief press will typically bring up a power menu for quick adjustments.
2. Touchscreen Interface
The Elite-5 Ti features a responsive touchscreen for intuitive navigation. Tap icons to select functions, swipe to scroll through menus or charts, and pinch-to-zoom on maps. Physical buttons on the right provide quick access to common functions like zoom (+/-) and waypoint marking (flag icon).

This image displays the Lowrance Elite-5 Ti unit, featuring its color screen split into two views: a traditional sonar view on the left and a Downscan Imaging view on the right. The screen shows detailed underwater structures and fish arches. The unit has physical buttons on the right side for power, zoom, and waypoint marking. The Lowrance logo is visible on the left bezel, and 'ELITE-5 Ti' is printed below the screen.
3. Sonar Modes (CHIRP and Downscan)
- CHIRP Sonar: Provides excellent target separation and clarity, ideal for identifying fish and structure in various water depths.
- Downscan Imaging: Offers a picture-like view of structure and bottom detail directly beneath your boat, enhancing understanding of underwater environments.
Switch between sonar views or use split-screen options via the touchscreen menu to optimize your fishing strategy.
4. Chartplotter and GPS
The built-in GPS antenna provides accurate positioning for navigation. The chartplotter displays detailed maps, allowing you to navigate, plan routes, and mark points of interest. You can enhance mapping capabilities by inserting compatible mapping cards.
5. Waypoint Management
Mark waypoints by pressing the flag button or tapping the screen. Waypoints can be saved, edited, and navigated to. While the unit defaults to numbered waypoints, options for naming waypoints may be available through software settings or future updates.
6. Advanced Features
- TrackBack: Review recorded sonar history to pinpoint specific structures or fish targets you may have passed over.
- Advanced Signal Processing (ASP): Automatically adjusts sonar settings to reduce noise and enhance target clarity, minimizing the need for manual adjustments.
- Wi-Fi Connectivity: Enables wireless software updates and allows for remote display and control of the unit via compatible mobile devices.
- Bluetooth Connectivity: Supports integration with compatible accessories, such as Power-Poles.
Maintenance
1. Cleaning
Clean the unit's screen and casing with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the display or housing. Ensure the unit is powered off before cleaning.
2. Software Updates
Periodically check for software updates to ensure your unit has the latest features and performance enhancements. Updates can typically be downloaded and installed via the unit's Wi-Fi connection.
Troubleshooting
- Unit Does Not Power On or Powers Off Unexpectedly: Verify the power connection and ensure a stable 12V power supply. Low voltage (e.g., below 12V) is a common cause of power issues. Check fuses and wiring for damage.
- Screen Displays Flashing Lines or Goes Blank: This can indicate an interference issue or insufficient power. Confirm the power supply is adequate and check transducer connections for proper seating. If the screen turns on and then immediately off, but buttons still respond (e.g., chirping sound), it may indicate a screen component issue.
- GPS Not Working or Inaccurate: Ensure the unit has a clear view of the sky for satellite reception. Check for any obstructions that might block the GPS signal. If the GPS stops working entirely, contact customer support.
- Sonar Readings Are Unclear or Absent: Inspect the transducer for damage or marine growth. Ensure the transducer is properly installed and submerged in water. Check transducer cable connections.
