​Stopping an oceanographic research vessel to occupy a fixed CTD station or suspend a hydrographic survey to perform water column sound velocity profiling can come at a substantial cost in terms of vessel productivity. Our rapidCAST profiling system eliminate the need to stop your vessel for upper ocean profiling. Data quality similar to stationary casts can now be obtained while fully underway. Innovative freefall probe systems designed in partnership with industry leaders SeaBird Electronics (USA) and Valeport Ltd (UK), deployed with our revolutionary compact deployment system now offers researchers and surveyors the profiles they need, with no loss of ship time.​​
