Garmin GT23M-TH Stainless Steel, TH Mount Transducer, Mid-Band CHIRP/CHIRP DownVü - 260/455kHz, 500W, 8-Pin

Designed for coastal and offshore anglers, the Garmin GT23M-TH Stainless Steel TH Mount Transducer delivers both traditional CHIRP sonar and CHIRP DownVü scanning sonar in a rugged thru-hull package. With a stainless steel stem and durable build, this transducer stays reliable in demanding saltwater conditions while delivering crisp readings beneath your boat.

The 8-pin transducer is built for versatile performance, featuring:

• Mid-Band CHIRP traditional sonar (80-160 kHz) with up to 600 W of power for strong, clear target returns and dependable bottom readings.
• CHIRP DownVü (260/455 kHz) scanning sonar with up to 500 W, providing high-resolution underwater imagery and precise structure definition.
• Stainless steel thru-hull mount for secure installation and long-lasting durability in harsh marine environments.
• 8-pin connector for straightforward integration with Garmin-compatible sonar systems.

This transducer is perfect for anglers who want the best of both worlds: traditional CHIRP yield for broad seabed understanding and DownVü scanning for detailed, fish-friendly views below the hull. Expect clear fish arches, superior target separation, and well-defined underwater structure that helps you locate fish faster and fish smarter.
