CR3 Hydrophone

The Cetacean Research™ CR3 hydrophone is an omnidirectional hydrophone.

C57 Hydrophones

Our new C57 hydrophones are in production and they sound fantastic!

The Cetacean Research™ C57 hydrophone series is an extra rugged version of our very popular C55 hydrophone; with a shape that allows it to be towed behind a boat with less flow noise. The C57 utilizes a slightly softer polyurethane encapsulation material than the C55, which results in even better underwater acoustic performance.

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 sources.
• 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.
