Collection: Garmin Marine Navigation Instruments & Transducers
Discover the full lineup of Garmin marine navigation instruments and transducers, featuring top-tier chartplotters, sonar modules, and sensor gear that elevate your onboard system. Whether you're upgrading your helm or building a networked marine electronics setup from scratch, this collection brings together Garmin’s most powerful instruments across series such as GPSMAP®, ECHOMAP™ / UHD2 / Ultra, Panoptix™, and LiveScope™ systems.
From the flagship GPSMAP chartplotter displays with integrated radar and advanced networking to ECHOMAP UHD2 chartplotter/sonar combos, you’ll find options suited for everything from inland fishing to coastal cruising and offshore expeditions.
- GPSMAP® Series — premium multifunction displays with 7” to 24” screens, built-in support for Panoptix™ live sonar, advanced radar integration, and seamless NMEA 2000 / Garmin Marine Network compatibility. These units serve as the command center of a full marine electronics system.
- ECHOMAP™ / UHD2 / Ultra Series — versatile chartplotter and fishfinder combos with support for CHIRP, ClearVü™, SideVü™, and LiveScope™ sonar imaging. These units often ship with preloaded Navionics+™ or enhanced Garmin maps and can wirelessly share routes and sonar data with other compatible Garmin displays.
- Transducers & Sonar Modules — including the LVS34 LiveScope™ transducer, GT-series scanning sonar modules (GT54, GT56, etc.), and Panoptix™ modules. These components enable real-time forward/down/perspective sonar views, ultra-high-definition structure imaging, and full 360° coverage when paired with capable chartplotters.
- Network & Integration Components — supporting accessories like radar domes, mount adapters, NMEA 2000 drop kits, network cabling, and sensor modules for a fully integrated marine electronics network.
Every product in this collection is engineered for marine durability—weather-sealed, vibration-resistant, and designed for long-term use in saltwater environments. Whether you’re piecing together a coastal day boat system or outfitting an offshore tournament rig, these Garmin instruments form a scalable, high-performance electronics backbone.
Get access to advanced navigation, sonar imaging, radar overlay, autopilot control, and synchronized data across multiple displays—all within one ecosystem. Explore the collection to equip your boat with Garmin precision and connectivity.
