The JLN-650 Doppler current meter is a black box-configured system designed for precise tidal current measurement, ship speed detection, depth analysis, fish locating, track plotting, and profile and graph display. It operates using a 125 kHz four-beam transducer and displays up to 100 layers of current direction and velocity using a dedicated twist mode for optimal net deployment timing. Continuous current measurement is available at five depths, including an auto-shift bottom layer feature. It tracks bottom currents up to 400 meters and automatically shifts to water tracking mode as needed. With integrated fish finding, self-test, and multiple alarm functions, the JLN-650 supports a wide range of marine and environmental applications.
