Non-Destructive Testing (NDT) is a critical component in ensuring the integrity and safety of industrial assets across the oil and gas, aerospace, and power generation sectors. As infrastructure ages and inspection requirements become more stringent, the industry has shifted from conventional Ultrasonic Testing (UT) toward advanced Phased Array Ultrasonic Testing (PAUT). This paper provides a technical analysis of the Gekko Phased-Array Flaw Detector, developed by Eddyfi Technologies. It explores the device’s hardware architecture, advanced software features—including Total Focusing Method (TFM) and Full Matrix Capture (FMC)—and its application in modern inspection workflows, particularly for corrosion mapping and hydrogen-induced cracking assessment. The deployment of the Gekko offers distinct operational
