The Cavision RS15SP-3 shoulder pad with rods connector makes shoulder-mounted shooting possible.
Purchased this Cavision shoulder pad to complete my Cavision hand held camera rig. Since all the parts are made by Cavision they fit and work well together. The only thing this unit needs is a strip of foam padding on the underside of the shoulder pad. I solved that problem by custom making a strip of foam about 1/4 inch thick that improves the comfort level.
Not the most well made piece of equipment, but it does what it's meant to do. For the price, you can't go wrong.
