Now with its new brightly colored AMOLED display; the Cygnus Dive Mk2 provides clear viewing from all angles for the diver and his camera, even in poor visibility. This robust, wrist-mountable, underwater, ultrasonic, metal thickness gauge has been designed for the professional diver and can be worn on the forearm, providing an invaluable free hand while performing metal thickness measurement surveys underwater. As with all Cygnus products, the Dive Mk2 has been designed for easy operation, and with only two buttons to operate, provides quick and easy menu navigation using just one hand.

Rated to a depth of 300 meters, the Dive Mk2 underwater thickness gauge delivers accurate meter readings, is reliable and simple to use. Topside Repeater can also overlay the real-time thickness measurement on to a composite video signal, displaying it on the monitor screen / video recording of the survey.

The Multiple Echo technique is at the heart of the electronics and ensures coatings up to 20mm thick are ignored and that measurements are automatically verified. The Dive Mk2 can measure through corrosion and through coatings up to 20mm thick (when in ‘Deep-Coat’ mode) using the Single Crystal Probe Option. The introduction of Twin Crystal Probe Option for use with the gauge in single-echo mode offers flexibility for specific situations where there are no protective coatings. These applications include uncoated surfaces with extreme front and back wall corrosion, anchor chain links and highly attentive materials such as cast iron.

The new CygLink v4 software offers a wide range of options for recording and displaying measurements. On-Board Data Logging Capability adds data logging capability to the gauge, supplied with CygLink software for data transfer and measurements can be recorded in either a linear or grid format.
