The Garmin GT56UHD-TH is an all-in-one thru-hull transducer designed for anglers who require maximum detail and versatile scanning ranges in a single installation. It features Ultra High-Definition (UHD) scanning sonar, providing significantly higher resolution than standard transducers, and is built with a rugged stainless steel stem suitable for various hull types.

This model is particularly effective for identifying fish tucked into structure or distinguishing between individual fish in a school. It supports three distinct frequencies for ClearVü and SideVü scanning, allowing you to prioritize either extreme depth/range or photographic-level detail depending on your environment.

Key Features

• Extended Range Scanning: The 455 kHz SideVü setting now offers a 20% greater range than previous UHD models, allowing for wider searches.

• Three Scanning Frequencies: Features 455 kHz, 800 kHz, and 1,200 kHz settings to balance depth performance and image clarity.

• High Wide CHIRP: Delivers traditional sonar with crisp target arches and superior separation in the 150-240 kHz range.

• Thru-Hull Design: The stainless steel construction ensures durability and is designed to provide clean water flow for consistent readings at speed.

• Vivid Color Palettes: Supports high-contrast sonar color schemes to make it easier to distinguish targets from the bottom.
