Ultrasonic Digital Thickness Gauge for Underwater Use, DIVE by Cygnus
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

Benefits of Cygnus Multiple Echo
With multiple echo, readings are taken by measuring the time delay between any three consecutive backwall echoes. The time of T1 (coating thickness) is ignored. The times of T2 and T3 are equal to the time that it takes to travel through the metal. Only by looking at three echoes can the measurements be automatically verified (where T2 = T3). |

Options and Accessories
Data Logging
Adds data logging capability to the gauge. Supplied with CygLink v4 software for data transfer. Measurements can be recorded in either a linear or grid format. Up to 5,000 measurements and A-Scans can be stored. The "Auto-Log” feature saves each stable measurement meaning the diver doesn't have to press a button every time a readings needs to be logged. Supplied with CygLink version 4 software.
CygLink v4 Software
CygLink v4 is a Windows® application and has two functions:
- It is used to transfer information from a data logging gauge to a computer. This can then be used to create reports, analyzed, stored and exported.
- As part of the CygLink Surface Display and Control Kit it can be used to provide a top side view of the survey. An umbilical cable is required to connect the gauge to the computer. This also allows the gauge set-up to be controlled from the surface, including logging readings during the survey.
Information displayed by CygLink includes; measurements, A-Scans, battery level, velocity of sound, measurement units, Deep Coat status and operating mode
 |
Once the survey results are in CygLink there is a range of different ways to view the data. This includes; linear, grid, color 2D and 3D representations. The data can be exported to a spreadsheet program e.g. Excel. The Ghost Overlay offers the option to pause an A-Scan that can be used as a reference trace. Measurements can be made on an A-Scan using two cursors |
| Topside Repeater Remote Display Kit The Cygnus Top Side 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 Top Side 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. Umbilical cables can be supplied made to custom lengths up to 500 meters (1,640 ft).

HelmetView™ Display
Remote display with fixing bracket for Kirby Morgan® helmets with an accessory mounting point.
Developed by Cygnus for divers in black or limited visibility water. The small remote OLED display is mounted just in front of the lens on the diver’s helmet. With adjustable brightness, the thickness measurement is clearly visible to the diver. When auto-log is being used, the HelmetView™ display will indicate when the reading is logged.
