I am buying a Pro + from someone but I am confused on the hierchy of these drones. Is a pro+ the same as V2 or is the v2 the newest Pro?

Hi there. Thank you for bringing this query to us. The Phantom 4 Pro + package includes a remote controller with a built-in screen and a standard Phantom 4 Pro without the "+" includes a standard remote controller. Being said, the Phantom 4 Pro and Phantom 4 Pro V2.0 is a different version, the Phantom 4 Pro V2.0 is the latest one. You may check the exact version of the unit that you are planning to purchase using the serial number on this link https://service.dji.com/active/search . Hope this helps. Thank you for your valued support.
