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.
