The Garmin GT30-TH is a specialized 12-pin thru-hull transducer designed for anglers who prioritize high-definition scanning sonar in coastal and offshore environments. It focuses exclusively on CHIRP ClearVü and CHIRP SideVü, providing exceptionally clear, photographic-quality images of structure, submerged objects, and fish without a traditional sonar element.

Encased in a rugged stainless steel housing, this transducer is built to withstand the rigors of salt water and is ideal for fiberglass or metal hulls. It is frequently used as a dedicated scanning supplement for vessels already equipped with a high-performance traditional transducer.
