NOVELTY - A detecting apparatus comprises a retractable pole (12) that can be extended at least two times its length when it is moved from retracted to extended position; and extendable elastic tube that can be extended at least two times its length when the retractable pole is moved from retracted to extended position.    USE - For detecting substance, e.g. natural gas from a distance.    ADVANTAGE - The invention has the capability to easily, conveniently, and quickly set up, assemble, use, disassemble, and store that saves time, reduces injuries to users and workers, reduces property damage, and performs an extremely valuable safety test. It easily retracts a telescoping pole through the use of an elastic tube and allows for easier use by the user and increased convenience. The use of elastic pole protects the apparatus from elements and reduces the chances of inaccurate readings.    DETAILED DESCRIPTION - A detecting apparatus comprises:    (i) a retractable pole having first and second ends (14, 16), first and second openings (18, 20), and a passage extending in the retractable pole from the first opening to the second opening;    (ii) an extendable elastic tube positioned within the passage of the retractable pole and operable to provide a path from the second opening of the retractable pole to the first opening;    (iii) a detector coupling (22) operable to couple with a detector (28) and to provide a path to the extendable elastic tube through the second opening of the retractable pole; and    (iv) a probe (26) operable to receive the substance and to provide a path to the extendable elastic tube through the second opening of the retractable pole. The retractable pole can be extended at least two times its length when it is moved from the retracted position to the extended position. The extendable elastic tube can be extended at least two times its length when the retractable pole is moved from the retracted position to the extended position.    An INDEPENDENT CLAIM is also include for a method for making an apparatus for detecting a substance comprising providing a retractable pole; positioning an extendable elastic tube within the passage of the retractable pole; providing a detector coupling; and providing a probe.
