881L Imaging Narrow Beam
Using Ethernet communications, this all-in-one, high performance digital imaging sonar can exceed 100 shots per second on the 1 m range at a 2 mm range resolution, producing near-photographic image quality.
The 881L can operate with customized configurations or revert to default settings to match appropriate operating range scales.
In addition to the benefits of low power, a simple set-up and installation procedure make this powerful sonar an ideal tool for remotely operated platforms ranging from large work ROV’s to small inspection vehicles, as well as AUV and UUV applications.
