The SQ91-00 hydrophone is made with a piezoelectric ceramic sphere and is
comparable to the RESON TC4037. The large 1” piezo element offers a high receive
sensitivity of -192.5 dB with a broadband receive capability at a 63 kHz resonance.
The SQ91-00 can be wired in series, to increase receive sensitivity further, and can
be paired with a preamplifier with a standard 40 dB gain, for an effective sensitivity of
-152.5 dB. Mounting points, connectors, and other parameters can all be
customized. Please contact us to discuss your specific requirements.
