Garmin, ECHOMAP™ UHD2 5″ cv Chartplotters 54cv with GT20-TM Transducer and Garmin Navionics+ U.S. Coastal & Great Lakes Mapping

The Garmin ECHOMAP™ UHD2 54cv is a compact, high-performance 5-inch chartplotter engineered for anglers and mariners who require precision sonar and professional mapping in a space-saving design. Built with a rugged, keyed interface, it is specifically optimized for reliability in environments where touchscreen operation is impractical.

Key Capabilities

Advanced Sonar Bundle: This package includes the GT20-TM transducer, which delivers two distinct sonar views:
- Traditional CHIRP: Provides crystal-clear target separation and crisp fish arches.
- ClearVü™: Offers a nearly photographic, high-definition view of structure and objects passing beneath the vessel.
Integrated Navigation: Preloaded with Garmin Navionics+™ coastal and Great Lakes mapping. This industry-leading cartography features 1-foot contours and Auto Guidance+™ technology, which calculates suggested paths based on your boat’s overhead clearance and depth requirements.
Wireless Ecosystem: Built-in Wi-Fi® allows for seamless wireless sonar sharing between compatible ECHOMAP UHD2 units. It also enables connection to the ActiveCaptain® app for smart notifications, software updates, and access to the Garmin Quickdraw™ Community.
Vivid Color Palettes: High-contrast color schemes for scanning sonar make it significantly easier to distinguish fish and structure from the sea floor or lake bed.

System & Design

Rugged Hardware: The unit features a bright, sunlight-readable display and a physical keypad designed for tactile feedback in all weather conditions.
Quick-Release Mount: The tilt/swivel mount allows for fast installation and removal, making it easy to secure the unit when leaving the vessel.
Quickdraw Contours: Enables users to map uncharted waters in real-time, creating personalized 1-foot HD contour maps as they navigate.
