What is the expected global accuracy of handheld scanners over larger distances?

I would like to include handheld scanning in our survey workflow for areas of poor access and poor line of sight. I had someone the other day recommend to me the peel 3d, claiming he was obtaining 0.2mm accuracy; though im sure this was the manufacturer rated accuracy to a single point, rather than a global accuracy of all points. I know many of you use the scanner for small parts, but how does it go for global accuracy? if i scanned a truck from one end to the other, will the distances between the corners be correct? does the accuracy improve with more passes? is there a general rule of thumb that can be applied here? Does the proprietary software allow for control to be included to adjust and position the network rather than a rigid transformation? i could easily layout a few control points with our tracker then observe them again with a scanner. I've had the peel3 3d recommended but I'm happy to hear other options. I have 0 experience with handheld beyond some youtube, so im unsure of their limitations.😅
