Kongsberg EM2040 Series Shallow Water Multibeam Echo Sounder

High-Resolution Seabed Imaging: A Full-Coverage Seabed Mapping Solution

The Kongsberg EM 2040 series multibeam echo sounder system is a world-leading solution for seabed terrain mapping and detection. This series covers a full range of application scenarios, from vessel-mounted installations to integration on USVs, ROVs, and AUVs. Renowned for its high resolution, high accuracy, and exceptional reliability, it fully meets and exceeds the highest international standards such as IHO Special Order and LINZ specifications.

This series comprises four core products, forming a complete technological lineup:

EM 2040C MKII: Circular dual-transducer design, 200° wide swath, cost-effective.

EM 2040P MKII: Compact structure, portable installation.

EM 2040 MKII — The series' high-performance flagship. Split transmit/receive design. 0.4°×0.7° ultra-narrow beams. 170° (single) / 220° (dual) swath. 6000m depth-rated option. The benchmark for professional ocean engineering and deep-water applications.

EM 2042 — Latest-generation lightweight, energy-efficient evolution of EM2040. Features QuadSwath™ and PredictivePitch™ for unparalleled data density and accuracy—ideal for small USVs in challenging sea conditions and high-speed surveys.
