The rapidCAST™ system enables hydrographic surveyors to eliminate survey downtime from sound velocity data collection, and to minimise bathymetry data uncertainty associated with challenging sound velocity conditions in the environment. The automated profiler offers SV casts to depths greater than 500 meters at 5kts without the requirement of an operator on deck. Simply enter the depth of profile required into the software running on the survey PC and the rapidCAST deploys to the desired depth and recovers the probe safely. With a minimal deck footprint, quick mobilization on practically any survey vessel, and a high-quality direct-reading SV probe, the portable rapidCAST provides near real-time SV data for the survey system. When surveys are accomplished with the greatest safety, efficiency, and accuracy using rapidCAST, savings in time and operating costs are the results.

Additional features:

• Patented line payout tension control for consistent drop rate
• Deep (5m/s) or shallow (2.5 m/s) profiling modes
• Deploys to target depth automatically—prevents hitting the bottom
• Recovers to designated hold position behind the ship while data are auto-uploaded wirelessly
• Short turnaround time between casts
• 5% depth accuracy at towing speeds up to 12 knots
• 1200m cast depth at stationary or low tow speeds
