The Cygnus DIVE is a robust, wrist-mountable ultrasonic underwater thickness gauge – providing an invaluable free hand while performing Ultrasonic Thickness Measurement (UTM) underwater. The large, bright display with Live A-scan is easily viewable by both the diver and his camera – even in the poorest visibility. With only two buttons to press, the gauge is very easy to navigate through an intuitive, user-friendly menu.
Ideal for use in hull UTM inspection, civil engineering, marine structures, offshore platforms, underwater structures, e.g. bridges, tanks, canal locks, subsea pipelines and equipment, UWILD or IWS class surveys
Cygnus Instruments builds all of its equipment in the UK using only genuine and original parts and components – including Lemo® Connectors and Peli® Cases.
Key Features of the Cygnus DIVE Underwater UTG
Three Versatile Measuring Modes
Measurement Stability Indicator (MSI™)
Exclusive to Cygnus, MSI™ ensures stable and therefore reliable measurements are displayed in Echo‑Echo and Single-Echo modes.
CygLink Computer Software
CygLink is a Windows® based application used to transfer and manage data logger records, A-scans, measurement comments and material velocity tables. The program can generate PDF reports and export to Excel. It also displays A‑scans, allowing for after-the-event analysis of logged measurements.
The latest version of CygLink software is available to download from ‘Software Downloads’.

To compliment our ultrasonic thickness gauges we offer a range of ultrasonic probes. The performance of any ultrasonic thickness gauge relies heavily on the probe and its suitability to the material being measured. Therefore, selecting the right probe is vital. All Cygnus’ probes are made from stainless steel and have a hard wear face or a wear membrane to protect the probe.

Twin Crystal Probes
Topside Repeater (TSR) Remote Display Unit
The Cygnus Topside Repeater is a remote display unit connected to the DIVE gauge with an umbilical cable. It displays the thickness measurements at the surface in real-time during the survey.
Topside Repeater with Video Overlay
The Topside Repeater can also overlay the real-time thickness measurements on to a composite video signal, displaying it on the survey monitor screen. It will also then be recorded (if there is a video of the survey), showing exact locations and the thickness measurement for future reference.
This is a remote display with a fixing bracket for Kirby Morgan® Helmets that have an accessory mounting point. This is depth rated to 300 m (984 ft), and designed for use in situations with extremely poor visibility and ease of viewing by the diver.
