Cygnus Underwater – Thickness Gauge for Divers
Cygnus Underwater is a handheld ultrasonic gauge designed for underwater use, specifically developed for diving inspections at depths of up to 300 meters. It uses multiple-echo technology to measure wall thickness through coatings—without damaging the material.
With a clear display, glove-friendly buttons, and a rugged design, it is ideal for offshore, marine, and underwater inspection applications where fast and reliable measurements are required.

3 measurement modes for different corrosion levels, material types, and measurement through coatings

Depth Sensor – displays the diver's current depth in real time

Live A-scan – provides visual confirmation of each measurement

Very easy to use—only 3 function buttons and up to 4 screen views

Comprehensive data logging – supports both linear and grid-based logging

Deep Coat function – ignores thick surface coatings during measurement

Built-in real-time clock (RTC) – time and date stamps for each measurement point

Automatic Gain Control – automatically optimizes probe performance

Multiple-Echo Mode – for reliable measurement through coatings, in accordance with classification society requirements

MSI (Measurement Stability Indicator) – confirms that the measurement is stable and therefore reliable
