The 2-axis mounts with pan and tilts angle protractors, slots, tilt axes, so the angles can be read out. The addition of the pan dial raises the mount 1/16 inch. Each of the pan and tilt protractor dial mounts is virtually identical to its dial-less cousin. As can be seen in these photographs, the 3-inch diameter tilt protractor dial is 1 inch wider than the 2-inch wide camera platform and 1 inch wider than the 2-inch wide rectangular and l-bracket mounting plates. Also, the pan protractor dial raises the mount 1/16 inch more above the base plate.
