The latest innovation from the pioneers of the digital multiple echo ultrasonic thickness gauge, the Cygnus
DIVE is designed for the professional diver and is accurate, reliable and easy to use. Worn on the diver's forearm, it gives an invaluable free hand while performing thickness surveys.
Made from a tough glass-filled resin, the Cygnus DIVE can withstand all the knocks and bumps of the diving environment. A large bright colour TFT screen displays the thickness measurements in big numbers that really stand out - choose the display colour that suits you.

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 gauge 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 1 metre in length for reaching around structures. A replaceable membrane ensures long probe life.

A-Scan Display
To assist with the verification of thickness measurements, and to help locate suitable ultrasound reflectors on badly corroded metal, the Cygnus DIVE can display an AScan graph of the ultrasound received.
When a multiple echo thickness measurement is detected the ultrasound peaks used are clearly marked to aid measurement confirmation.

Surface View
The A-Scan graph can be viewed at the surface on a computer using Cygnus
DIVELink software and the A-Scan graph is also recorded when data logging thickness measurement points.

Top Side Repeater (TSR) - Optional
The Top Side Repeater is a small display unit that can be used to display the thickness measurements sent from the DIVE gauge to the surface.

TSR Video Overlay Facility
The Top Side Repeater can also superimpose the thickness measurements on to a composite PAL or NTSC video signal to display it on a monitor screen and/or the video recording of the survey. This provides a thickness measurement that can be linked to a position or place in the video recording.
Kit includes data and video cables.

Optional HelmetView™
Often divers face taking thickness measurement surveys in black or limited visibility water so Cygnus developed HelmetView™.
A small remote display is mounted just in front of the lens on the diver’s helmet using the accessory screw, a short cable then plugs in to the Cygnus DIVE's top side data connector.
Thickness measurement values are then clearly visible to the diver - even if they can't see any further.
Thickness measurements are clearly displayed on an OLED display and its brightness can be adjusted from the menu on the Cygnus DIVE gauge.

Data Logging Option
The Cygnus DIVE can store up to 5000 thickness measurement points in internal flash memory.
Thickness measurements are recorded using an Auto-
Log feature that saves each stable measurement -
this means no ‘log’ button for the diver to press.

A-Scan Graph
Along with the thickness measurement, a copy of the A-Scan graph is also saved.
Data logged measurements are easily transferred from the Cygnus DIVE to a computer using the DIVELink software supplied. From there a paper report can be produced or the thickness
measurements can be exported to a spreadsheet.
Measurements can be split into groups by simply starting a new group via the DIVE’s easy to use menu.

DIVELink Software Option
Cygnus DIVELink software provides a top side view of thickness measurements, A-Scan graphs and instrument status on a computer.

Data Logging
DIVELink can be used to record thickness measurements as part of a thickness survey. The operator can choose to log the thickness measurements taken by the diver, or using the A-Scan graph estimate the thickness and record this value instead - useful when gauging on heavy corrosion.
Instrument Status and Control

DIVELink allows an operator to see the battery status of the Cygnus DIVE.
The material velocity, unit and Deep Coat settings can also be changed
from the surface.

Deep Coat
The Deep Coat function allows the Cygnus DIVE to measure metal thickness through coatings up to 20mm thick.
