My personal opinion is that superior versitility makes a high quality PC/scanner/monitor combination a far better option for technologically-comfortable examiners than any comparator. Firstly, zoom capabilities of most imaging software provide views for the level of detail being examined. Enhancement techniques of forensic imaging applications afford more detail while maintaining documentation of those enhancement steps. And more advanced software allows an examiner to view image intensity information as a surface and tilt that surface. One major benefit of this type of comparison tool is that you can look down the ridges and furrows, but the focal plane is rotated with the image. In a spotty ninhydrin print, for example, you can see all the spots in perfect focus, even though you are looking down the ridges at, let's say, a 5% angle with the surface. This allows for reliably and objectively "connecting the dots" while viewing in focus; something that no comparator can come close to doing.

My agency is purchasing a table model comparator and I am looking for feedback/complaints/praises from anyone who has used one. Specific information about the FX10B Optical Comparator would be greatly appreciated.
