The LanParte HHG-01 Handheld Gimbal allows you to capture stabilized, free-floating shots with your GoPro. It features a motorized three-axis gimbal and a 6-axis IMU (Inertial Measurement Unit) designed to keep your phone level and isolated from shakes and jitters. Rather than keep your device locked in place along three axes, the Handheld Gimbal allows it to follow the tilt and pan motion of your wrist, while keeping the horizon level. This gives a more organic feel to your footage and intuitive operation. Two mounting clamps are included, allowing attach smartphones from 2.2″ to 2.5″ wide (iPhone 4, 4s, 5, 5s, or similar sized phone) and 3″ to 3.6″ wide (iPhone 6+ or similar sized phone).
