South SDE 260D Product Review

Precision Meets Power in the South SDE 260D Echo Sounder

When accuracy, efficiency, and reliability are non-negotiable in hydrographic survey operations, the South SDE 260D emerges as a game-changer. This dual frequency digital echo sounder is engineered for professionals who need trustworthy depth data in complex underwater environments. Whether you’re mapping shallow waters or detecting deep sediment layers during dredging construction, the South SDE 260D Echo Sounder delivers seamless performance.

Overcoming Surveying Challenges with Innovative Technology

Hydrographic surveying often comes with multiple pain points: muddy waters, quicksand layers, floating debris, and noisy hull interference. The South SDE 260D directly addresses these issues with its advanced digital processing and echo detection technology. With standard dual-frequency capabilities at 200 kHz and 20 kHz, this echo sounder ensures high-frequency precision and deep low-frequency penetration. It effectively filters out false readings, guaranteeing accurate depth measurements even in challenging environments.
