The magnetic 6” Straight Ruler is ideal for use around metal while taking evidence photos. Measurements are in both inches and millimeters and the crosshair circles at each end assist in photogrammetry corrections. Its flat color and non-glare plastic reduces reflections. A blank area in the middle of each scale can be used to write initials, case number, or other pertinent information. Easy to tuck in a pocket or bag!

Good item, I missed the boat when I thought there were more in the package.
