UM384K Bottom Recorder is an autonomous recorder based on UM384K board. The
electret microphone present in the UN384K
microphone is replaced by a preamplified
microphone sensor, SQ29 specifically designed to
bring the right sensitivity for marine

This device implements all the characteristics of
Um384K ultrasonic microphone.
The circuit board is integrated in a plexiglass can,
with two caps and the hydrophone sensor placed
in one of them. The container is tested for up to
500 mt deep use, and it is intended to be used
only in autonomous mode.
