The Flycam Flowline 400N Stabilizing Camera Support from Proaim redistributes the weight of your camera setup from your arms to your back, enabling you to hold the camera steady for longer periods of time without fatigue. Designed to support rigs weighing from 17.6 to 22 lb, this system's durable suspension line hooks onto the camera rig and transfers the weight to the harness while also reducing shake and vibration.
The Flowline 400N consists of a harness-style vest that fits a wide variety of body sizes, an adjustable waist belt from 34 to 56", and a height-adjustable support arm that extends from the back of the harness over the operator's head. The end of the support arm features an extendable suspension line with a camera hook that connects to the top of your camera or gimbal rig. A soft carrying case is included to store and transport the entire rig.
