Second and third portions of flexible tubing operatively couple the transparent shield to the handle, the second portion of flexible tubing having a mass per unit length that is less than a mass per unit length of the first portion of flexible tubing. The third portion of flexible tubing includes a mass per unit length that is less than the mass per unit length of the first portion of flexible tubing. The proximal end of the first portion of flexible tubing is attached to an anchor. |
