The Garmin GT30-TM is a 12-pin transom-mount transducer specifically engineered for high-definition scanning sonar in shallow to mid-depth waters. Unlike many multi-purpose transducers, this model focuses exclusively on CHIRP ClearVü and CHIRP SideVü, providing remarkably clear, photographic-quality images of underwater structure, submerged objects, and fish.

Because it does not include a traditional sonar element, it is an ideal choice for vessels that already have a high-performance traditional transducer installed and require a dedicated scanning supplement. It is also a popular pairing for the GCV™ 10 sonar black box module.

Key Features

• Specialized Scanning: Dedicated solely to ClearVü and SideVü to provide high-resolution imagery without interference from other sonar types.

• CHIRP Technology: Sweeps through a range of frequencies (455/800 kHz) to deliver superior target separation and crisp detail.

• Wide SideVü Range: Capable of scanning up to 500 feet to each side of the boat, making it highly effective for scouting large areas for bait and structure.

• Versatile Mounting: Includes both transom and trolling motor mounts for flexible installation across different boat types.

• Temperature Sensing: Built-in high-response temperature sensor provides accurate, real-time water temperature data.
