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 & stability by putting the centre of the overall rig & equipment weight in line with your body's centre 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.
