SmallRig Magic Arm Magnetic Suction Cup Mounting Support Kit for Action Cameras 4466 is designed to shoot car scenes using an action camera. It is only recommended to be used on flat iron surfaces, such as iron doors, railings, kitchenware, sports equipment, etc. The exclusive dual-material design combines magnets with a vacuum sucker, ensuring safer, longer-lasting, and more stable shooting. Even in the unlikely case of silicone suction cup leakage due to severe vibration, the magnets can pull the whole mounting support to the surface of an iron car (within the load capacity of 0.35kg / 0.8lb in a dynamic shooting scene with a flat road when maximum speed does not exceed 120km/h or 74mph), effectively avoiding the risk of falling off caused by the leakage of a silicone suction cup. The kit includes a magic arm, a magnetic suction cup, and an action camera mount. The 1/4""-20 screw on one end allows attaching an action camera, LED video light, etc. The included action camera mount supports GoPro Cage 3084C / 3083C, Frame for Insta360 X3 4088B, and DJI Action 4 Cage 4119B. Similar products from SmallRig include 3566, 4193, and other camera mount supports.
