The metal or ABS Omniprism is a C shaped accessory with Cylindrical target within. It fits on Tripods and Tribrachs or can be screw threaded into tunnel or ground anchors for traversing and profiling. Railway surveying is not especially accurate with a pole and prism balanced on the running edge so the Sentripod railshoe is exactly contoured to sit on the Rail and presenting the target perpendicular to the running edge, no matter if it is flat or super elevated round bends.
