Introducing the Garmin GT34UHD-TM Transducer Transom Mount 12-Pin — the ultimate upgrade for fishermen seeking unmatched imaging. Designed to pair with compatible Garmin chartplotters via the GCV 20 sonar module, this Ultra High-Definition (UHD) transducer delivers crystal-clear ClearVü and SideVü scanning sonar that reveals structure, fish, and relief below and to the sides of your boat.

Ultra High-Definition Imaging

This transducer features 3 arrays, including a downward-facing element, with a broad frequency range of 0.8 MHz (800 kHz) to 1.2 MHz (1,200 kHz). The result is brilliant image clarity at greater depths, letting you identify targets sooner and more accurately. See every contour of the bottom and every fishy hotspot with UHD precision.

Crystal-Clear Depth and Side Scanning

Ultra High-Definition ClearVü provides exact, down-looking detail with a CHIRP range of 760–880 kHz. Ultra High-Definition SideVü opens a wide view to the sides with a 1.2 MHz CHIRP range of 1,060–1,170 kHz. Combined, you gain a comprehensive picture of the underwater environment—beneath your boat and off to each side—for faster, smarter fishing.

Power, Beam, and Depth you can Trust

• Power: 500 watts for strong, clear returns.
• Beamwidth: ClearVü 0.74° x 46°, SideVü 0.44° x 55° for highly focused detail.
• Maximum depth: ClearVü up to 200 ft down; SideVü up to 125 ft to the sides (250 ft total coverage).

Rugged, Easy-to-Install Transom Mount

• Connector: 12-pin configuration for reliable data transfer.
• Cable length: 20 ft for flexible mounting options.
• Transom compatibility: Supports 0°–70° deadrise/transom angles for a wide range of hull designs.
• Downward-facing element: Adds extra power on targets at depth, delivering sharper images where you need them most.

Compatibility and How It Helps

Designed to work with Garmin chartplotters that support UHD scanning via the GCV 20 sonar module, the GT34UHD-TM helps you scout faster, plan better, and locate bites with confidence. The combination of ClearVü and SideVü imaging lets you map the bottom structure, locate schools, and pinpoint fish hangouts—all in stunning detail.
