The Imagenex 881A Narrow Beam Digital Imaging Sonar is a compact, high‑performance imaging system engineered to deliver near‑photographic subsea visuals. Using efficient serial communications, it achieves more than 35 shots per second on the 1‑metre range with a 2 mm range resolution, giving operators exceptional clarity for close‑range inspection and survey work.
Its flexible configuration options allow the sonar to operate with customised settings or revert to default modes to match the required range scale. With low power consumption and a straightforward installation process, the 881A integrates seamlessly across a wide range of platforms, from large work‑class ROVs to small inspection vehicles, as well as AUV and UUV systems. This makes it a strong choice for offshore oil and gas inspection, diving support and general surveying, and it is equally effective in more specialised tasks such as sunken timber recovery, search and recovery operations, underwater archaeology and scientific research
