Kongsberg EM 2040 MKII: High-Resolution Multibeam Echosounder

The Industry Standard for Shallow-Water Hydrography and Inspection

Product Overview

The Kongsberg EM 2040 MKII is a true wideband, high-resolution multibeam echosounder (MBES) designed for the most demanding shallow-water mapping and inspection tasks. Built on the success of the original EM 2040, the MKII version introduces an expanded frequency range and enhanced processing power, making it the first system to bring deep-water multibeam features—like 3-sector transmit and frequency modulation (FM)—into the near-bottom environment.

With an operational frequency range of 200 kHz to 700 kHz, the EM 2040 MKII allows operators to choose between maximum depth penetration and surgical imaging resolution on the fly. It is fully compliant with IHO S-44 Special Order and the even more stringent LINZ specifications.

Why Choose the Kongsberg EM 2040 MKII?

• Unprecedented Resolution: With a raw range resolution of just 10.5 mm and beam widths as narrow as 0.4°, it is the premier tool for detecting small subsea objects, wrecks, and pipeline anomalies.
• Predictive Performance: Features complete roll, pitch, and yaw stabilization, ensuring high data quality even in rough sea states that would ground other survey vessels.
• Broadband Versatility: Use 200 kHz for depth (up to 600m), 300 kHz for standard mapping, and 400–700 kHz for ultra-high-resolution structural inspection.
• Efficiency Boost: The Dual Swath option effectively doubles the ping rate, allowing for higher vessel speeds while maintaining full sounding density along the track.
