Key Feature of the Cygnus DIVE Underwater Ultrasonic Thickness Meter
- Multiple-Echo mode for accurate, through-coat measurements as specified by Classification Societies
- Single-Echo and Echo-Echo modes for heavily corroded metals with a thin or no coating
- Deep-Coat function to ignore coatings up to 0.8 inch (20 mm) thick
- A-scan display to assist with measurement verification
- Optional Data Logging feature with Auto-Log – storing up to 5000 measurements including A-scan data without pressing any button
- MSI™ (Measurement Stability Indicator) verifies stable, reliable readings
- Rechargeable lithium-ion battery giving up to 10 hours continuous measurement
- Optional remote display HelmetView™, Topside Repeater and CygLink surface display software.
Display 2.8” quarter VGA color LCD (320 x 240 pixels). Large clear thickness measurement (15 mm high numbers), viewable from all angles. A-scan display with automatic X axis. Battery level, signal strength, transducer type, velocity. Measurement mode and units indication.
Battery Single 3.6V Li-ion 8.2 W battery. 10 hours continuous measurement. Low battery warning ‘alert’ message.
Measuring Modes Multiple-Echo using 3 echoes to ignore coatings up to 0.8 inch (20 mm) thick
Echo-Echo using 2 echoes to ignore coatings up 0.04 inch (1 mm) thick
Single-Echo using 1 echo
Deep Coat In Multiple-Echo mode, allows measurement to be made through thicker coatings of suitable materials of up to 0.8 inch (20 mm) thick
Accuracy ±0.1 mm or 0.1% of thickness measurement, whichever is greatest, when calibrated in accordance with Cygnus Instruments calibration procedure

Topside Repeater (TSR) Remote Display Unit
The Cygnus Topside Repeater is a remote display unit connected to the DIVE meter 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 984 ft, and designed for use in situations with extremely poor visibility and ease of viewing by the diver.
