Obviously I don't have permission for the first link. All the same I was able to look at the second link very quickly, and could see a very high quality of work.
After contacting Mad Max, I will come back to the forum to bring the information mentioned and which will have allowed me to make my choice on the scanner or even the scanners.
There would be this scanner recommended by Mad Max : http://www.aniwaa.fr/blog/prise-en-main-et-test-du-nouveau-shining-3d-einscan-pro/
and would see to buy a Faro or Romer type Arm scanner.
