The Cetacean Research™ nano Remote Underwater Digital Acoustic Recorder (nRUDAR-mk2™) is a hand-held, ultra compact, short-term, autonomous underwater recording device that is designed for a wide range of applications.
Uses of the nRUDAR-mk2™ vary from manual underwater recording while diving to autonomously recording wild cetacean vocalizations for several days continuously. This makes it an excellent tool for recording high resolution audio for underwater video production, as well as scientific research
The Cetacean Research™ RUDAR™ (Remote Underwater Digital Acoustic Recorder) is a compact, long-term autonomous recording device that is light enough to be deployed by hand from small boats.
The RUDAR™ system utilizes the data acquisition and processing components of the ST1400ENV mobile data recorder & sound level monitor. Interchangeable Cetacean Research™ C57- or C305- series hydrophones are used for signal detection. This system has very low power consumption that allows extended remote recording sessions and continuous high-speed data acquisition.
The Cetacean Research™ µRUDAR-mk2™ (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 of the µRUDAR-mk2™ range from remote detection of methane bubbles to recording wild cetacean vocalizations for periods of more than two days.
The µRUDAR-mk2™ uses the same hydrophone element and preamplifier as our Sensor Technology SQ26-08 hydrophone along with a 24-bit, 96kHz digital recorder.
