Common questions
What is the difference between BrassTRAX and IBIS TRAX-3D HD?+
BrassTRAX-3D HD is dedicated to imaging cartridge cases, while the broader TRAX-3D HD platform also captures bullet surfaces, so a lab may run both modules to cover the full range of fired evidence.
Does a high BrassTRAX correlation score establish a legal identification?+
No. The score ranks stored images by topographic similarity for investigative leads; a certified examiner must still perform independent microscopic comparison before reporting an identification.
