nRUDAR Autonomous Underwater Signal Recorder
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 vary from manual underwater recording while diving to autonomously recording wild cetacean vocalizations for several days continuously.
