The Polar Pro Lens Cover/Gimbal Lock for the DJI Phantom 3 protects the gimbal and camera during travel. The lens cover pushes onto the gimbal, locking it in place to prevent damaging movement during travel. The lens cover also fits over filters when installed protecting filters, and the camera lens from bumps and scratches. The Phantom 3 lens cover is constructed out of a durable soft touch, glass filled nylon. Make sure your Phantom 3 is undamaged and ready to fly with the Polar Pro Lens Cover and Gimbal Lock.
