Premium remote network sonar solution.

The GSD 25 Premium Sonar Module is a remote network solution that provides outstanding fishfinding and bottom tracking capabilities.

Clearest scanning sonar images on the water: Adding CHIRP technology to ClearVü and SideVü scanning sonar further enhances the resolution, target separation and clarity of the sonar images of fish and structure that pass below and to the sides of your boat. The images sent to your compatible Garmin chartplotter have target details so clear and precise, you can actually distinguish between small and closely spaced fish at key fishing depths all the way down to 5,000 feet.

True dual-channel 1kW CHIRP:  CHIRP is the most sophisticated sonar technology available for use by the fishing and boating public. CHIRP is an acronym for Compressed High-Intensity Radiated Pulse. What it means to you is much better target resolution, clarity and crispness than any other sonar system. Having Garmin’s true dual 1kW CHIRP as your traditional sonar allows you to adjust CHIRP frequencies to low/medium, low/high, medium/high to further optimize your sonar performance.

This sonar is so unique that Garmin has developed their own proprietary transducers that are specially designed to work with this new sonar to provide the very best performance. Transducer sold separately.
