Overview
Garmin ECHOMAP Ultra 2 12" Chartplotter with GT56UHD-TM Transducer and Navionics+ Australia Mapping
Introduction
The Garmin ECHOMAP Ultra 2 125sv is a 12-inch marine chartplotter built for anglers and boaters who need detailed underwater imaging, reliable GPS positioning, and seamless navigation across Australian and New Zealand waters. Bundled with the GT56UHD-TM transducer, this system pairs traditional CHIRP sonar with Ultra High-Definition ClearVü and SideVü scanning technologies to deliver near photo-like views of fish, structure, and bottom composition. Whether fishing inland lakes, coastal bays, or deeper offshore environments, the ECHOMAP Ultra 2 provides the sonar clarity and charting accuracy needed to fish smarter and navigate with confidence.

Data Insights
The GT56UHD-TM transducer's Ultra High-Definition ClearVü sonar produces remarkably detailed underwater imagery that helps anglers distinguish individual fish from structure, vegetation beds, and bait concentrations with greater precision. SideVü scanning technology expands coverage laterally from the vessel, improving target identification across wider search areas. The bundled one-year Navionics+ subscription delivers daily chart updates, ensuring depth contours, hazard data, and navigational information remain current for Australian and New Zealand waters. Split-screen display configurations allow simultaneous monitoring of detailed bathymetry charts alongside real-time sonar feeds, reducing the time required to interpret underwater conditions and make fishing decisions.
Usage Instructions
Install the ECHOMAP Ultra 2 using the included quick-disconnect bail mount, then secure the GT56UHD-TM transducer to the hull following Garmin installation guidelines. Power on the unit and configure sonar colour palettes, chart zoom levels, and GPS preferences to match your fishing style. Use Garmin Navionics+ mapping to mark productive waypoints, create saved routes, and preview depth contours before departing. Download the ActiveCaptain app to access software updates and upload Quickdraw data from your device. If running multiple compatible Garmin displays onboard, enable wireless networking to synchronize sonar data and navigation information across all units for enhanced crew awareness.
Design & Material
The ECHOMAP Ultra 2 125sv combines a large 12-inch display with a compact, marine-grade housing designed for durability in salt spray and freshwater environments. The quick-disconnect bail mount system allows fast removal and secure storage when the chartplotter is not in use. Control buttons and the intuitive menu interface are positioned for easy one-handed operation while underway. The display delivers bright, high-contrast imagery in direct sunlight, and split-screen layouts maximize information density without sacrificing readability.

- CHIRP sonar frequency variable across multiple ranges for optimal target separation at all depths
- Vivid high-contrast sonar colour palettes designed for target distinction and reduced interpretation time
Final Verdict
The Garmin ECHOMAP Ultra 2 125sv with GT56UHD-TM transducer is a professional-grade chartplotter and sonar system for serious fishing operations across Australian and New Zealand waters. The Ultra High-Definition ClearVü and SideVü sonar technologies deliver the underwater detail needed to identify holding structures and fish with confidence, while Garmin Navionics+ mapping and multi-band GPS provide reliable navigation and positioning. With NMEA 2000 compatibility, wireless networking, Force trolling motor integration, and a one-year chart update subscription, this system scales from single-display operation to full-vessel marine ecosystems.
