© 2008 GENERAL ACOUSTICS GmbH Your Creative and Innovative Technology Company since 1996 High Resolution at Good Penetration SUBPRO 1210 Sub Bottom Profiler The SUBPRO 1210 breaks the limitations of existing SBPs SBP e.g. linear-, chirp-, parametric systems: - high resolution means a low bottom penetration - good bottom penetration means low resolution - limitations at operation in shallow water - low detection probability of embedded objects and sediments - different SBP tasks require different SBP systems

© 2008 GENERAL ACOUSTICS GmbH Your Creative and Innovative Technology Company since 1996 SUBPRO 1210 is… a high quality, universal system for wide range of sub bottom surveying tasks fulfils the requirements for most sub bottom surveying tasks in only one system developed for shallow to medium water depth suitable for all sizes of survey-vessels or ships as a portable or in-hull mounted system a complete measuring system and easy to integrate in complex survey systems sufficient from survey to the scientific market and from helmsman to experienced survey engineer
