The PolarPro Tablet Extension allows you to use larger tablets with cases installed with select DJI remotes. The Tablet Extension easily slides onto the top section of the DJI remote allowing you to quickly install and remove the mount. We developed this product to eliminate the need to remove the iPad case every time we flew. Additionally, we wanted to use larger tablets than what the stock DJI remote allowed. With the PolarPro Tablet Extension you can use tablets as large as the iPad Pro 12.9in (with a case on).
