The ergonomically designed housing combined with its light weight, reduces operator fatigue and strain permitting better and longer inspections. The compact design allows the WC-9 to fit into confined spaces better than our full-size W-Series Models. Combined with our Universal Articulating Pole Pieces, the WC-9 can fit almost any configuration of work piece. All W-Series Yokes have more height between the operator’s hand and the work piece, which means faster inspection due to a larger view of the target area.
