Abstract
A pocket sized telescopic level apparatus includes a plurality of at least three telescoping tubular sections including a largest section and sequentially smaller sections, each section having an exterior diameter and a longitudinal bore with an interior diameter, and wherein the sections are of sequentially larger external diameter so that one section fits into an adjacent section and all sections are contained upon the largest section in a collapsed position. A level bubble member is disposed at an end portion of the largest section and a plurality of shims form interfaces between the end portions of adjacent sections upon extension of the apparatus. The shims are tubularly shaped and positioned between the outer wall of an end portion of one section and the inner wall of an adjacent section.
