The SQ03 is a high sensitivity hydrophone (-164 dB) that operates well beyond the audible range, up to 65 kHz. An ultra-high sensitivity (-148 dB) variant is available as the SQ31. Both hydrophones provide a reliable solution for a wide variety of uses including general maritime applications, academic research and low frequency seismic monitoring (when paired with our infrasonic preamp). These hydrophones are available with an optional protective cage.
