Cygnus DIVE Underwater Tester
Ultrasonic Thickness Tester
Key features of the Cygnus DIVE underwater ultrasonic thickness tester include:
- Multiple-Echo for accurate through-coat measurements, as specified by Classification Societies
- Echo-Echo and Single-Echo modes for heavily corroded metals with a thin or no coating
- Deep-Coat function to ignore coatings up to 20 mm thick
- A-scan display to assist with measurement verification
- Optional Data Logging feature with AutoLog – storing up to 5,000 measurements including A-scan data without pressing any button
- MSI™ to help verify stable and reliable readings
- Rechargeable lithium-ion battery giving up to 10 hours continuous measurement
- Optional CygLink software, Topside Repeater and HelmetView™.
Three Versatile Measuring Modes
- Multiple-Echo: Uses three error checked back wall echoes to provide the most reliable and accurate remaining thickness measurements, with no need to remove coatings (up to 20 mm thick).
- Single-Echo: Ideal for measuring uncoated metals with heavy front and/or back-wall corrosion. Also effective on a range of cast metals, plastics and composites.
- Echo-Echo: Works best for measuring heavily corroded metals through thin coatings of up to 1 mm thick, ideal for measuring painted metals with heavy back wall corrosion.
MSI™ (Measurement Stability Indicator)
Exclusive to Cygnus, MSI™ ensures stable and therefore reliable measurements are displayed in Echo‑Echo and Single-Echo modes.
CygLink 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.

We used the 5MHz dual crystal as it gave the best results on the pitted steel we found on the many corroded ships hulls where we tried the UT gauge. The DIVE was reliable, very easy to use, has simple menu system and displays. The logging function was essential as we only had 13 minutes on the wreck each day; I could make lots of measurements and figure out the answer back home in post processing, we also didn’t have to write anything down or think too much as thinking isn’t so easy in 40m water with the effects of narcosis!

We have used the equipment with very good results on a job so far.

Regarding the MK-2 this has been working very good and we did over 1.000 readings with the same battery on two different days; we are completing a serial of surveys on pontoon ferries with a total of 4,000 readings and so far we are very happy with the device performance.

The Cygnus DIVE was simple to use and, like all Cygnus kit, it was good and rugged.
The large display was excellent – and clearly visible even in darker water. Readings were easy to take and snapped up on the screen quickly -which makes our job as divers so much easier.
The twin crystal probes were particularly useful on areas of very heavy corrosion.
