High-Performance Doppler Volume Sampler (DVS) for Precision Marine Profiling

The Doppler Volume Sampler (DVS) offers high spatial and temporal resolution for short-range profiling. Designed for marine environments, the DVS comes in two models: the 750m and 6000m systems. Weighing less than 7.6 kg in air for the 750m model and 19.1 kg for the 6000m model, this equipment is compact yet robust. Features include a 16KByte flash recorder, battery pack, and various optional sensors and connectors. Ideal for oceanographic studies, it ensures accurate data collection with minimal shipping concerns.
