Claim:
A leg for use in supporting geomatic equipment comprising a first leg section and a second leg section, the first leg section being telescopingly received into an interior of the second leg section for selective extension from and retraction into the second leg section to lengthen and shorten the leg, and a locking device including an actuator and an engagement portion positioned to act on the interior of the second leg section to lock the first and second leg sections relative to each other to fix the length of the leg, the locking device being operable in a lock position in which the engagement portion of the locking device bears against the second leg section on the interior thereof with a force selected to lock the first and second leg sections, and an unlock position in which the engagement portion is spaced from the second leg section such that the leg sections are free to move in telescoping relation to change the length of the leg, the engagement portion comprising a resilient member made of elastomeric material, the resilient member having edges spaced axially of the leg, the thickness of the resilient member tapering from a central region thereof toward the axial edges.
