Magnum Plus Mirrors feature a stem that moves the mirror head outward 2 farther than our Magnum Mirror. In addition to the standard flat glass, which allows a larger image but a narrower field of view, a convex version is also available. The advantages of convex, reduced image mirrors are two-fold. First, one has a wider field of view with this style mirror, although the image you see does appear smaller, or farther away. Secondly, vibration has less of a distorting effect with a convex mirror. All Magnum Plus Mirrors are beautifully chrome-plated.
