Kongsberg EM 2042: Next-Generation Multibeam Echosounder

Ultra-High Resolution & Lightweight Design for Shallow-to-Mid Water Mapping

Product Overview

The Kongsberg EM 2042 represents a significant leap in multibeam echosounder (MBES) technology. Specifically designed to be 60% lighter than its predecessor (the EM 2040), it is engineered for rapid deployment on a vast range of platforms—from large survey vessels to small Uncrewed Surface Vehicles (USVs) and inflatable crafts.

Operating across a wide frequency band from 150 kHz to 700 kHz, the EM 2042 provides the flexibility to balance depth penetration with surgical imaging precision. With integrated 4D motion compensation and the revolutionary PredictivePitch™ technology, this system delivers "clean" survey data even in challenging sea states, effectively extending your operational weather windows.

Why Choose the Kongsberg EM 2042?

• Unrivaled Portability: Weighing significantly less than previous generations, it reduces the complexity of over-the-side mounting and is ideal for weight-sensitive autonomous platforms.
• PredictivePitch™ Technology: A first-in-class feature that predicts vessel motion to steer transmit beams accurately, ensuring even data distribution in rough waters.
• QuadSwath™ Capability: Delivers up to 4 swaths per ping cycle, providing the extreme sounding density required for high-speed surveys and detailed object detection.
• Simplified Integration: Uses a single subsea cable to connect the sonar head to the processing unit, minimizing failure points and streamlining mobilization.
• No Export License Required: Designed for global ease of trade, the standard 50m depth-rated unit is generally free from legacy export restrictions.
