A 3-axis gimbal is a camera stabilization device that uses three brushless motors and precision sensors to eliminate jerky movements on the tilt (Y-axis), pan (X-axis), and roll (Z-axis), providing smooth, stabilized footage. Key features often include intelligent object tracking, motion time-lapses, and specialized creative shooting modes, while typical specifications involve payload capacity, battery life, weight, and specific angling capabilities for tilt, pan, and roll.
