A communication device is disclosed having a first housing member and a second housing member, each with an inner surface. The housing members are rotatably coupled together so that the inner surface of the first housing member is biased towards the inner surface of the second housing member. Each housing member includes an electronic circuit portion that is also coupled together. In addition, the mass of the first housing member is substantially equivalent to the mass of the second housing member so that when the communication device is attached to an object, it remains balanced about the object.
