Happy 2024.👍😀
I'd agree, especially if you're using the Olympus RDC which is little more than a modified direct reading thickness gauge. This gets even harder in the areas of multiple thicknesses such as door surrounds etc.
Whist you can use a standard A Scan ultrasonic test set for this, it will give you much more information but you still have to map out the individual thicknesses and that takes quite a bit of time.
The easiest option is to use phased array ultrasound that will give you a 2D image of what you're inspecting and only takes a couple of minutes to cover a relatively large area, the only downside to this is cost as the instrument and probe cost around 40K.
