Garmin GT34UHD-TH Transducer Thru-Hull 12-Pin

The Garmin GT34UHD-TH Transducer is a thru-hull sonar solution for Garmin chartplotters using the GCV 20 module, delivering Ultra High-Definition ClearVü and SideVü imaging. Its three-array design, including a downward-facing element, enhances target clarity at depth and broadens your scanning reach.

• Three-array design: Provides beneath-hull and side scanning for rapid area coverage with exceptional clarity.
• Downward-facing element: Concentrates power on targets to reveal deeper bottom detail and improved visibility of underwater structures.
• Frequency: Ultra High-Definition ClearVü: 0.8 MHz (800 kHz), CHIRP 760–880 kHz; Ultra High-Definition SideVü: 1.2 MHz (1,200 kHz), CHIRP 1,060–1,170 kHz.
• Power: 500 W for bright, detailed echoes across both ClearVü and SideVü modes.
• Beamwidth: Ultra High-Definition ClearVü: 0.74° x 46°; Ultra High-Definition SideVü: 0.44° x 55°.
• Maximum depth: ClearVü up to 200 ft; SideVü up to 125 ft per side (250 ft total).
• Features: Depth and Temperature data are included for enhanced situational awareness.
• Number of pins: 12
• Cable length: 20 ft
• Supported deadrise/Transom angles: Supports hulls with up to 25° deadrise; optimal performance on hulls up to 5° deadrise.
• Compatibility: Seamless integration with Garmin chartplotters via the GCV 20 sonar module.

This transducer delivers highly detailed underwater imagery to enable precise bottom analysis, clear structure identification, and reliable fish targeting. The dual high-frequency imaging beneath and to the sides helps you quickly scout water, while the downward-facing element enhances target visibility in deeper water. With a robust 500 W output and carefully tuned beamwidth, you’ll see sharp echoes in both modes even in challenging conditions. The 20 ft cable and 12-pin connector simplify installation on a wide range of boats, and its Garmin ecosystem compatibility ensures a smooth sonar experience alongside your chartplotter and mapping data.
