SQ26-H1B Hydrophone

The SQ26-H1B is a general purpose hydrophone ideal for whale watching and full audio-band signal detection. It can also be used as a contact microphone or low cost geophone. The SQ26-H1B hydrophone is the base for our SQ26-H1 system.

The SQ26-H1B is a great kayaking hydrophone and a wonderful recreational boating accessory.

An excellent option is to pair the SQ26-H1B hydrophone with a bluetooth speaker – chose from headphones or a waterproof speaker (mounted with a suction cup capable of sticking to the outside of your kayak or top of your boat deck).

CR1 Hydrophone

Cetacean Research™ CR1 hydrophones are excellent multi-purpose hydrophones. The most recent release of the CR1 is the CR1A.

Various uses are detection & recording of very loud signals, listening & recording of quieter sounds like cetaceans, whale watching operations, and terrestrial applications.

• This non-preamplified hydrophone is ideal for the detection and recording of very loud signals; such as those from pile driving, air guns, or underwater demolition operations.
• In addition, the CR1 series can be used with an external preamplifier (such as the ART USB Dual Pre) for recording and listening to the quieter sounds of cetaceans and other underwater sourc
• The CR1 series models also serve very well as a robust hydrophone for whale watching operations when used directly with a battery powered portable amplifier.
• Terrestrial applications for the CR1 series hydrophones include vibration detection and use as a geophone.

The hydrophone comes with an extra tough, flexible coaxial cable. The cables can be terminated with either BNC or mono phone plug connectors. All CR1 series hydrophones are individually spot calibrated at the factory.
