Enhance your offshore fishing adventures with the GSD™ 25 Premium Sonar Module, a cutting-edge remote network solution designed to deliver exceptional fishfinding and bottom tracking capabilities. Engineered for seamless integration with Garmin chartplotters, the GSD 25 provides clear, precise sonar images, allowing you to identify and locate fish even at depths of up to 5,000 feet.

Advanced Sonar Technology

The GSD™ 25 Premium Sonar Module utilizes Garmin’s most advanced sonar technologies to ensure you receive the highest quality underwater imaging. Whether you're navigating deep waters or seeking out the best fishing spots, the GSD 25 delivers reliable performance and unparalleled clarity.

True Dual-Channel 1kW CHIRP

Experience the power of Garmin's True Dual-Channel 1kW CHIRP technology. CHIRP, or Compressed High-Intensity Radiated Pulse, offers superior target resolution, clarity, and crispness compared to traditional sonar systems. With adjustable CHIRP frequencies—low/medium, low/high, and medium/high—you can optimize your sonar performance to suit various fishing conditions.

Note: Transducer sold separately.

Superior Scanning Sonar Imaging

The GSD™ 25 elevates your sonar imaging with CHIRP DownVü and SideVü scanning capabilities. This dual scanning sonar provides detailed views of fish and underwater structures passing below and to the sides of your vessel, ensuring you never miss a catch. Integrated into Garmin’s GPSMAP xsv combos and the GSD 25 Premium Sonar Module, it requires only one transducer for both traditional CHIRP HD-ID sonar and scanning sonar functionalities.
