The new Cygnus Underwater gauge is tailored for professional divers performing offshore maintenance, ship surveys and marine civils inspections. 

“Beyond its exceptional new look and ergonomic design, the most apparent advancement for the new Cygnus Underwater is the jump to a multi-mode gauge,” said a Cygnus Instruments spokesperson.

“The new Cygnus Underwater now offers a versatile solution for varying levels of corrosion and various materials, as well as through-coat measurements, giving you peace of mind in any inspection scenario.”

Powerful tool

Its ergonomic design, intuitive controls and advanced multi-mode functionality make it a powerful tool for corrosion measurement in challenging subsea environments.

Key features include a full-colour LCD screen visible in murky waters, live depth display via an integrated depth sensor and support for Multiple-Echo, Echo-Echo and Single-Echo modes.

This versatility enables accurate ultrasonic measurements through coatings or heavily corroded metals, essential for Class Society-approved testing and inspections.

The Cygnus Underwater is designed for diverse applications, from Mobile Offshore Units (MOUs) and ship hulls to underwater pipelines and civil structures like piers and dams. It helps vessels avoid unnecessary dry-docking by enabling in-water surveys (UWILD/IWS), significantly cutting downtime and operational costs.

For marine civils and subsea infrastructure, where safety and longevity are paramount, Cygnus said that the new gauge delivers unmatched reliability and usability.

With fast setup and auto-optimised gain settings, divers can stay focused on safety and precision, even in the most demanding underwater conditions.
