This invention provides azeotrope-like compositions of 1,1,1,2-tetrafluoroethane, 1,1,1,3,3-pentafluoropropane-245fa and 2-methylbutane that are environmentally desirable for use as refrigerants, aerosol propellants, metered dose inhalers, blowing agents for polymer foam, heat transfer media, and gaseous dielectrics. The fishing pole holder includes a first end having a receiving cavity configured to receive the stock of a fishing pole, and a second end having a plurality of teeth for insertion into the ground, so as to securely anchor the second end into the ground. A time-of-flight measurement of this path length provides an accurate measurement of the internal diameter of the pipe.
