Setup
The 2MHz Aquadopp Profiler, designed for current measurements in shallow water (offering a 10m profiling range), is set up using the Nortek deployment software, enabling users to customize measurement schemes and assess power requirements.
Deployment
Compact size and an optional right-angle head allow for very near-bed deployments, maximizing water column coverage in shallow areas. Teams of all sizes can deploy an Aquadopp Profiler successfully.
Data
Nortek postprocessing software and/or display software is available for review, visualization, and processing of data, after deployment or in real time.
