You can think of the DJI Mavic Pro as pocket sized phantom 4 quadcopter with the only compromise being a slightly lower flight time.  The Mavic still has the same forward looking stereo cameras for obstacle avoidance, and subject tracking, but because of its foldability, it can fit easily into your backpack, or even your pocket if you have a very big pocket!.  This means that you can actually carry it around with you on your adventures without any extra hassle.  Other impressive features include the ability to fly faster than the phantom 4 at 40mph (just 5mph slower than the inspire one), and with the new ocusync video transmission system you can get over 4 miles of video range.  You also have the option to fly this drone with the remote control, or just via wifi through your smartphone.
