Probing is used to quickly setup/find zero points on a vise, fixture or part. Accurately sets zero points, finds edges, center locations of bosses or bores, slots and webs. Eliminates the need for a centerfinder or an edgefinder. You'll never have to spend 30 minutes using a center finder to locate the center of a bore again. The probe will find and set the center of a bore in just seconds. In addition the probe can be used to verify part dimensions.
