With the Katana from Polar Pro, you will change your DJI Mavic drone into a regular video camera, handheld. The quality of the DJI Mavics camera and the resolution of 4K are quite high so its a shame to use them only for aerial recordings. The camera is perfect for recordings on earth. Thats why Polar Pro has designed the Katana: a tray to hold your DJI Mavic folded, to bring it easily. This allows you to make recordings of the hand, on the ground. Naturally, when you make recordings, you want to see what you are recording. For this, your smartphone can function as a screen if you use the Katana, just as if the drone is mounted in the air. That is why the Katana has a mount for smartphones up to the size of the iPhone 7 Plus with case. With the Katana, you can use all functions of the DJI Mavics camera. For example, the gimbal of the DJI Mavic takes care of a stable image. With the katana, you can use your DJI Mavic drone in areas where flying is not allowed. Ideal for pilots who want to shoot movies!
