The Garmin GSD 24 is a digital black box network sounder engineered for high-definition sonar performance across a wide range of depths. Delivering up to 2,000 watts of transmit power paired with a high-dynamic range receiver, it connects directly to compatible Garmin Marine Network chartplotters for fast, shared sonar data with minimal screen delay. Dual-frequency operation and selectable power levels make it equally useful for offshore sportfishing and nearshore structure scouting. Existing GSD 22 users can upgrade using the included adapter for improved performance.
