The Cetacean Research™ µRUDAR™ (micro Remote Underwater Digital Acoustic Recorder) is a very compact, short-term, autonomous recording device that is designed for fast and easy deployment in a wide range of applications.

Uses range from remote detection of methane bubbles to recording wild cetacean vocalizations for periods of more than two days.

The µRUDAR™ uses the same hydrophone element and preamplifier as our Sensor Technology SQ26-08 hydrophone along with a 24-bit, 96kHz digital recorder.

This easy-to-use recording system can be deployed to depths of up to 100m and will provide more than 18 hours of continuous 24-bit, 96kHz sample-rate data acquisition, and up to 61 hours at 16-bit/44kHz sample-rate.
