Garmin GT30-TH Thru Hull Scanning Transducer

The Garmin GT30-TH Thru Hull Scanning Transducer is purpose-built for anglers and boaters who demand premium sonar clarity in shallow to moderate water conditions. This 12-pin thru-hull transducer delivers the advanced scanning capabilities serious fishermen rely on to locate structure, baitfish, and bottom composition with confidence. Whether you're working coastal flats, rivers, or inland lakes, the GT30-TH bridges the gap between entry-level transducers and high-end systems, offering professional-grade imaging at a practical price point.

Built with a stainless steel stem for superior corrosion resistance and durability, the GT30-TH employs Garmin's proprietary CHIRP ClearVü and CHIRP SideVü scanning sonar technologies to paint exceptionally detailed views of the water column and surrounding terrain. ClearVü provides traditional forward-looking sonar with enhanced definition, while SideVü sweeps outward to reveal structure and targets alongside your vessel. The dual-frequency capability and advanced signal processing eliminate the guesswork from depth, temperature, and fish identification, allowing you to make informed decisions about where and how to fish.

Installation is straightforward for boats with compatible Garmin chartplotters and multifunction displays; the 12-pin connector integrates seamlessly with the Garmin ecosystem, and the thru-hull design ensures reliable performance season after season. This transducer is ideal for recreational anglers upgrading their electronics, tournament competitors who need consistent, repeatable sonar data, and boaters operating in freshwater or saltwater environments where pinpoint accuracy matters. Weight of 6.16 lbs requires proper mounting hardware to ensure secure installation and optimal transducer face alignment for best imaging results.
