The Garmin GSD 24 Digital Black Box Network Sounder brings high-definition sonar capability to vessels running compatible Garmin Marine Network chartplotters. With selectable transmit power up to 2,000 watts, a high-dynamic range receiver, and dual-frequency operation at 50 kHz and 200 kHz, it handles everything from nearshore structure scanning to deep offshore water columns reaching 5,000 feet. High-speed network sharing means every connected display receives sonar data with minimal lag. Existing GSD 22 owners can step up to the GSD 24 using the included adapter without a complete system overhaul.
