2023 Garmin Marine GSD™ 25 Premium Sonar Module Base

2023 Garmin Marine GSD™ 25 Premium Sonar Module

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 true dual 1 kW CHIRP as your traditional sonar allows you to adjust CHIRP frequencies to low/medium, low/high, medium/high to further optimize your sonar performance. Transducer sold separately.

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. Built-in to our new GPSMAP xsv combos and GSD 25 Premium Sonar Module, it uses 1 transducer for traditional CHIRP HD-ID sonar and CHIRP ClearVü and SideVü scanning sonar. Transducer sold separately.

This new sonar is so unique we have developed our own proprietary transducers that are specially designed to work with our new sonar to provide the very best performance. See our Transducer Selection Guide to find a transducer that's right for you.
