C13 Hydrophone

The Cetacean Research C13 hydrophone has been replaced with the Cetacean Research CR1 hydrophone.

Cetacean Research™ C13 hydrophone with cable

The following is retained for reference. See the CR1 page for a current Cetacean Research hydrophone designed for very loud signal detection.

The Cetacean Research C13 hydrophone is similar to the C10 hydrophone model with the addition of a ruggedized cable and a research-grade connector. The C13 hydrophone model is ideal for very loud signal detection such as pile driving and air guns. Hydrophones are not individually calibrated.
