The depth probe and the film are not parallel. The image will be distorted.
SNIPER X-RAY consists of a base that attaches to the radiographic film holder.
The base can be fixed / inserted on both side of the film holder.
The depth gauges are manufactured in different lengths and diameters.
The depth gauge is screwed to the base.
The depth gauge is fixed parallel
to the film.
Thanks to SNIPER X-RAY, the X-RAY tube is perpendicular
to the film and the depth gauge.
