RoxAnn GD is a remote sensing hydro-acoustic sensor providing seabed classification data to produce seabed bottom type maps.

RoxAnn GD uses a patented technique to extract data on bottom roughness and hardness from the first and second echosounder returns from the seabed. It interfaces with a Global Position System (GPS) and PC enabling real-time seabed classification and mapping of geological and biological features using RoxMap Software.

This system has been in use for over a decade in a wide variety of applications and has a number of benefits to the user including being easy to use.
