With its bright, very large, AMOLED display the Cygnus DIVE is simple to operate, providing accurate and reliable thickness measurements.  Depth rated to 300 metres.

Available with data logging, topside, HelmetView™ and twin crystal probe options.

MSI™ Measurement Stability Indicator - this is a feature exclusive to the Cygnus. When using the DIVE Gage in Single Echo mode, MSI™ confirms when a reading is stable by turning the thickness measurement numbers from red to yellow.

Manufactured in the UK, Cygnus DIVE is designed for the professional diver.

The Cygnus DIVE is a wrist-mountable, simple to operate, robust underwater ultrasonic thickness gauge which provides an invaluable free hand while performing remaining metal thickness measurements. The Cygnus pioneered Multiple Echo technique is the heart of the electronics and ensures protective coatings up to 20 mm (0.787") thick are completely ignored, there is no need to remove protective coatings. Additionally, all measurements are automatically checked and verified by the Multiple Echo technique electronics.

The large, bright color AMOLED display is easily viewable by both the diver and his camera even in the poorest visibility and the operation of the gauge couldn’t be simpler, only two buttons for easy navigation of the intuitive, clear menus.

The completely new feature of the DIVE is the added flexibility of single echo mode where twin crystal probes can be used. This feature is useful for some specific situations including on; uncoated surfaces that have extreme front face and back wall corrosion and anchor chain links.

Simple Operation

Like all Cygnus products, the Cygnus DIVE has been designed for easy operation. There are no gates to set up, no gain to adjust - just turn on and go. There are two buttons for quick and easy menu navigation using one hand; from here you can access all the functions of the gage guided by intuitive, clear menus.

Rechargeable Batteries

Power is supplied by a replaceable, rechargeable Lithium Ion battery pack that gives up to 10 hours continuous operation.


Measurement Technology

The Cygnus DIVE uses the trusted Multiple Echo Technique first developed by Cygnus over 25 years ago. With minimal surface preparation, the Cygnus DIVE will measure metal thickness through paint and other coatings, even light marine growth. The Multiple Echo Technique ensures only genuine, verified thickness measurements are displayed.

Ultrasonic Probe

The ultrasonic probe is connected to the Cygnus DIVE by a coiled double jacket cable and rugged locking connector. The coiled cable will extend up to 3 feet in length for reaching around structures. A replaceable membrane ensures long probe life
