Manfrotto MVA521W Sympla Counterweight (Black)
When using SYMPLA as a shoulder-mounted rig, using counterweights at the back of the rig, securely attached to the shoulder support pad, can aid balance and stability by putting the center of the overall rig and equipment weight in line with your body's center of gravity. The counterweight screws securely on to the SYMPLA Shoulder Pad via a 3/8” thread. Counterweights can also be stacked to offset very unbalanced loads.
