Conclusion

• The comparative analysis confirmed that applying a wedge delay calibration introduces variances in the PA and DA readings across both devices.
• Even with wedge delay actively applied to both systems, there remains a marginal discrepancy from the actual physical location of the defect.
• Overall, the detection capabilities and accuracy in pinpointing defects proved to be highly comparable between the DEEPSOUND P5 and the Third-Party equipment.
