GSD™ 26 CHIRP Professional Sonar Module

Experience incredible clarity and detail from shallow to deep water. GSD™ 26 features CHIRP technology — continuous sweep of frequencies ranging from low to high which puts more energy on the target to provide images so crisp you can actually distinguish between small and closely spaced fish at key fishing depths.

GSD™ 25 Premium Sonar Module

Designed for the avid to serious fisherman, the GSD™ 25 premium sonar module provides both true 1 kW CHIRP sonar along with Garmin CHIRP SideVü and ClearVü scanning sonar.

Powerful, dual-frequency remote sonar with selectable transmit power up to 2 kW to provide pinpoint accuracy at depths of up to 5,000 feet (1,500 m). You get enhanced separation of images and deeper bottom detection for a clear view of fish, terrain and structure on your compatible Garmin chartplotter.
