Abstract
A telescoping leg particularly adapted for use in supporting geomatic equipment is capable of locking in different selected positions of extension. A lock is provided for holding the leg at the selected position of extension. The lock is biased to a lock position, but is capable of being moved and retained in an unlock position by operation of a single thumb on one hand so that locking and unlocking the leg for telescoping movement occupies only one hand.
