ABSTRACT:
The telescopic measuring pole consists of an extensible pole which can be adjusted between a length of 32.5 inches and 15.5 feet. The pole has a removable hardened point on one end and accommodates prisms or receivers of various technologies via an adapter on its opposite end. The pole utilizes an over-center cam lever to clamp the telescoping tubes in precise fixed positions relative to one another. The clamping mechanism is designed and manufactured to minimize friction and galling, and can be operated with one hand.
