Impact Subsea are proud to present the ground breaking full ocean depth ISA500 Underwater Altimeter. 

Based on the ISA500 architecture, the full ocean depth ISA500 is optionally available with integrated Attitude and Heading Reference System (AHRS). 

The ISA500 utilises a broadband composite transducer together with an advanced digital acoustic engine to provide the highest level of stability and range available from a 500kHz Altimeter. 

With integrated AHRS, the ISA500 has the ability to compensate for pitch and roll - providing a true altitude reading at all times. For applications where Altitude, Heading, Pitch and Roll are required; all can be provided from a single device.
