HY1602 Dual Frequency Echo Sounder System, with DSP and digital imaging technology, embedded industrial control system and data acquisition software, is an all-in-one PC based dual frequency echo sounder, which can output both echogram and thermal chart paper result simultaneously. Its main features as follows: Standard computer for easy operation interface and data storage, advanced bottom digitizer, internal large storage of data to file with time Reference, digitized depth, position heave and annotations. It is a perfect choice for surveying in the river, lake, ocean and so on. Function Dual Frequency and Double channel Output both echogram and thermal chart paper result simultaneously Based on the computer platform and have a slave display TVG/AVG dynamic adjustment, reinforced anti- jamming ability Low noise receiving ability and space filter, Time filter adjustment High speed USB interface, huge storage capacity Echogram output for real time display, storage, playback and printing Multi-ports communication for GPS, motion sensors and so on Bundled data acquisition software like HYPACK, EIVA.
