Impact Subsea ISA Series Underwater Altimeter and Echo Sounder

The Impact Subsea ISA Series is a revolutionary line of underwater altimeters and single-beam echo sounders, with its core advantages being millimeter-level measurement accuracy and an optional integrated Attitude and Heading Reference System (AHRS). This series includes two main models, the ISA200 and ISA500, operating at 200kHz and 500kHz respectively, to meet varying requirements for range and resolution in different applications.

The ISA Series employs an advanced digital acoustic engine and a wideband composite transducer. Combined with real-time roll and pitch compensation from the AHRS, it ensures accurate true altitude above the bottom regardless of the carrier's attitude. The products are available with titanium or acetal housings, and offer forward-looking or right-angle configurations, with depth ratings covering from 1000 meters to 11,000 meters, making them ideal for ROVs, AUVs, and various underwater monitoring tasks. The ISA500 model was awarded The Queen's Award for Enterprise 2021 (Innovation).
