A grounding system for a fiberscope utilizing an electrically conductive braid surrounding at least a portion of a flexible hollow tube containing fiber optic bundles. According to the invention, by simplifying the Peterson-Gorenstein-Zierler algorithm the goal of correcting different numbers of errors using a single hardware architecture is achieved. A valve is coupled to the cuff; the valve configured to permit flow in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction. The positioning block contacts the drag adjustment lever to position the drag adjustment lever at the intermediate position. Optionally, the bag can have compartments, pockets, andor a removable liner.
