Impact Subsea are proud to present the ground breaking ISA500 family of altimeters. Highly robust, with optional 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.
