Drones, and DJI specifically, have come a long way in the last few years. Flight distances, telemetry, obstacle avoidance, silky smooth gimbals, high quality cameras, and size reduction are just a few of the areas that have improved massively.
DJI has just addressed two more issues in an effort to perfect the quadcopter with their latest DJI Mavic Pro Platinum. The Mavic Pro Platinum has an 11% gain in flight time (30 minutes) and a 60% reduction in noise (4dB less). The Mavic Pro Platinum is already for pre-sale at $1,099, a $100 increase over the Mavic Pro.
