The Ergorig can prevent spinal compression while allowing an operator to operate handheld like they would traditionally, without affecting the camera's movement or balance. 100% of the weight is transferred from your shoulder and back to your hips, bypassing your spine entirely. There is a way to handhold a camera ergonomically, and this is it.
