A support particularly adapted for supporting a geomatic pole has telescoping legs, each having telescoping leg sections which can be locked by a locking device in a selected position of extension, fixing the length of the leg. The locking device is easily actuated and released and is biased toward a locked position. In an unlocked position, the locking device is positively positioned to inhibit contact with the released leg section so that movement is smooth and unnecessary wear is limited. The locking device has an engagement portion which is constructed to promote locking, but also to facilitate release and limit unnecessary wear of the engagement portion.
