AQUAmark 848

The AQUAmark 848 is a programmable acoustic pinger designed to deter marine mammals from fishing gear and man-made hazards. Its programmable nature allows research scientists to evaluate different acoustic signal types to determine the optimum deterrent solution for a given marine mammal interaction. The instrument is available to qualified research institutions for discounted purchase on a data sharing basis. It is also available for commercial rental in a pre-configured form for marine mammal mitigation applications.
