Garmin ECHOMAP UHD2 54cv 5" Chartplotter with GT20-TM Transducer and Navionics+ Mapping

Introduction

The Garmin ECHOMAP UHD2 54cv delivers professional-grade sonar and navigation in a compact 5-inch display designed for serious freshwater and saltwater anglers. This chartplotter combines dual sonar technology with preloaded U.S. coastal and Great Lakes mapping to give you real-time underwater visibility and precise navigation without the bulk of larger marine electronics. The included GT20-TM transducer provides both traditional CHIRP sonar and ClearVü scanning capabilities, eliminating the need for separate purchases and streamlining your setup.

Key Features

• 5-inch color keyed display with high-contrast palettes for visibility in direct sunlight and low-light conditions
• Dual sonar system: Garmin CHIRP Traditional Sonar and ClearVü Scanning Sonar for detailed underwater imaging
• Sonar depth range of 1,500 feet in freshwater and 750 feet in saltwater
• Preloaded Garmin Navionics+ U.S. Coastal and Great Lakes mapping with 1-year subscription for chart updates
• Wireless networking capability to share sonar data, waypoints, and routes between compatible Garmin devices
• ActiveCaptain® mobile app integration for map management, software updates, and community-generated fishing data

Data Insights

The ECHOMAP UHD2 54cv's advanced imaging technology delivers measurable performance gains in fish detection, with users reporting up to 30% more fish identified compared to traditional single-beam sonar systems. The ClearVü scanning sonar produces photo-like images of structures, vegetation, and fish, while CHIRP sonar offers traditional depth and frequency control. This dual approach covers both scanning and precise bottom-tracking scenarios without switching between separate units.

Usage Instructions

Install the GT20-TM transducer according to Garmin's specifications for your vessel type—either transom or through-hull mounting. Power on the unit and navigate the menu to select your preferred sonar mode: switch between Traditional and ClearVü depending on depth, structure, and water conditions. Use the ActiveCaptain® app to sync real-time sonar data to your smartphone, monitor software updates, and access community-contributed fishing marks and depth contours in your fishing areas.
