Vectograph is a useful thing for cops. In general, it helps to better understand what kind of find lies under the coil, helps to hear and see a deep target that is difficult to pick out, and also helps to determine its size. Using a vectograph? Regarding the vectograph on XP Deus — from version 4.0 it is available for public use and removed from the engineering menu.
Old video and from VaDyan. It was a long time ago, but in general, the work of the vectograph has not changed.
And a cop with a vectograph.
I hope the video makes it clear and helps you find more with XP Deus!
