Description

The Cygnus DIVE is a durable, wrist-mounted ultrasonic thickness gauge designed for underwater use, allowing divers to perform Ultrasonic Thickness Measurement (UTM) hands-free. Its large, high-visibility display with Live A-scan ensures clear readings for both the diver and their camera, even in low-visibility conditions. With just two buttons and an intuitive user interface, navigation is simple and efficient.

Ideal for hull inspections, civil engineering, marine structures, offshore platforms, subsea pipelines, underwater structures, and UWILD/IWS class surveys, the Cygnus DIVE is a powerful tool for professionals working in demanding underwater environments.
