Garmin GT34UHD-TM Ultra HD Transom Mount Transducer

The Garmin GT34UHD-TM Ultra HD Transom Mount Transducer is purpose-built for anglers and boaters who demand crystal-clear sonar imaging on the water. Mounted cleanly to your boat's transom, this transducer feeds ultra high-definition ClearVü and SideVü scanning sonar data directly to your compatible Garmin chartplotter, letting you see structure, baitfish, and bottom composition with unprecedented clarity. Whether you're targeting bass in shallow lakes or walleye in deep reservoirs, this transducer transforms raw sonar data into actionable underwater visibility.

At 2 pounds and measuring 7 x 4 x 10 inches, the GT34UHD-TM is engineered for easy installation and minimal drag while delivering maximum sonar performance. The transom mount design allows for simple, secure attachment to most boat sterndrives and outboards without requiring hull penetration. Ultra High-Definition imaging technology captures detailed 2D views of underwater terrain and fish, while SideVü scanning extends your view corridor left and right of the boat's path—essential for identifying drop-offs and cover that traditional sonar alone would miss. The transducer operates seamlessly with Garmin's ecosystem of compatible chartplotters, ensuring reliable integration and consistent real-time data delivery.

This transducer is ideal for serious anglers upgrading their fish-finding capability or boat owners installing a new sonar system from scratch. Installation requires a compatible Garmin chartplotter unit; verify your current or planned display model supports GT34UHD-TM connectivity before purchase. The compact transom mount is suitable for powerboats, bay boats, and center consoles where a clean, low-profile transducer setup is preferred. Once mounted and paired with your Garmin system, you'll gain the ability to fish structure faster and with greater confidence, translating higher water clarity into more fish in the boat.
