SURVEYING & INSPECTION Your Solution to Shorter, Safer, Smarter Dives
For commercial diving teams under pressure to deliver accurate UT data quickly and safely, the Cygnus Underwater Diver Held Gauge sets a new benchmark. Built specifically for subsea and inland corrosion surveying, it delivers fast, accurate thickness measurements—even through coatings and heavy corrosion, while drastically reducing the operational burdens typically placed on divers.
Faster Measurements → Shorter, Safer Dives Every second underwater carries cost and risk. The Cygnus Underwater’s easy to use, quick to verify, accurate measurement capability—even in harsh conditions, combined with its Multiple Echo mode for automatically error-checked, reliable readings through coatings, means divers spend less time: • Removing coatings • Repeating scans • Stabilising the probe • Fighting currents or turbulence
This results in shorter bottom times and reduced exposure, especially vital in high risk inland environments like dams, sluices, and flowing water zones.
Engineered for Low Visibility — So You Don’t Lose Time Searching for Readouts Poor visibility shouldn’t compromise an inspection. This instrument’s large, highly visible, clear colour display ensures divers can read measurements even in murky, low- light conditions.
Paired with simple three quick function keys and an intuitive menu, divers can work confidently with minimal visual confirmation required.
The result? Faster measurements in fewer attempts, even when visibility is poor.
Unmatched Data Reliability — Stabilised, Verified, Automatically Logged When the pressure, movement, and acoustic chaos of underwater environments can distort readings, Cygnus delivers clarity.
Key innovations include: • Measurement Stability Indicator (MSI) to confirm when results are reliable;
• Auto Set Gain to optimise probe performance instantly under variable conditions;
• Live A Scans and topside repeating for visual confidence in challenging acoustics.
Combined with Multiple Echo validation—the gold standard—these features deliver industry leading measurement consistency, even when the diver cannot remain perfectly still.
Automatic, Time Stamped Logging — No Errors, No Lost Data, No Repeat Dives Documentation failures are one of the biggest causes of costly re dives. Cygnus eliminates this risk.
Its comprehensive linear and grid automatic data logging, paired with a Real Time Clock (RTC) for automatic timestamping of every reading, ensures complete data traceability. No verbal relaying. No transcription errors. No gaps. What’s more, the auto-log function facilitates accurate and efficient data capture. That means fewer missed points and fewer return dives, saving time, cost, and risk.
Designed to Reduce Diver Workload — Simple, Intuitive, One Hand Friendly Commercial divers already juggle buoyancy, communication, entanglement hazards, and tight spaces.
The Cygnus Underwater reduces the load with: • One hand operation • Quick function simplicity •
fFur easy navigate screens
Less cognitive load = fewer mistakes + faster, smoother inspections.
