The Merlin Arm & Vest System consists of the Merlin, arm, vest, and three additional stainless-steel 'mid-weights' to counterbalance cameras weighing up to 7.5 lbs (3.4 kg).The Merlin Gimbal employs six-ball bearings with aluminum and stainless-steel construction for precise movements, angular isolation, and higher payloads than its predecessor.Weighing only 2.6lbs, the Merlin Arm and Vest make extended shooting nearly effortless. It is light and thin enough to even be worn under a tuxedo jacket. All adjustments require no tools to fit any shape and size. It allows for hours of shooting without undue fatigue, and preserves all the flexibility and reach of the operator's own arms.The Merlin Arm is ultra-light and extremely capable. It provides great performance and flexibility including instant, knob-adjustable control of lifting power for camera payloads between 2.5 and 7 lbs. (1.1 to 3.2 kg) The Merlin Arm also provides enormous vertical lifting range (28” or 71cm) and full ‘iso-elasticity’ so you’ll need only ounces of force to maintain the highest or lowest lens heights (from way above the head to below the waist). Like its big brothers, the Merlin Arm includes two-axis adjustment of the arm-to-body angle so that people of differing shapes can adjust the lifting angle to their most comfortable posture.Together the Merlin Arm and Vest actually increase your shooting options. The operator can ease the Merlin back against the body and shoot 'handheld', with both hands on the camera, and fly seamlessly back off the shoulder and continue moving. With practice operators can fly the Merlin one-handed right off of the mounting post during a shot (docking the arm to the vest with the other hand) and execute those unique Merlin shot opportunities – ultra-low- or ultra-high-angles – and then slip it back onto the arm to continue the shot.Merlin GimbalVestArmThree Stainless-Steel 'Mid-Weights'
