The present invention relates to new compositions of matter, particularly metals and alloys, and methods of making such compositions. The core layer can be made from relatively lower cost, quality and weight materials, such as re-grind or recycled plastic materials, and the shell layer can be made from higher quality materials that are selected for durability, appearance and resistance to corrosion, mildew and impacts. The method may further comprise the step of determining whether the group has sufficient credit for acquiring the location of the portable communication devices in the group. The apparatus can further include a head capable of transmitting therapeutic energy to a treatment area, which can be precisely aligned by the user to a desired portion of the treatment area through the use of the display device.
