DJI - the world's bestselling drone manufacturer - has announced its first foldable aircraft to be targeted at consumers.

The Chinese company says the quadcopter can be compressed to roughly the size of a water bottle for transportation.

The Mavic Pro's launch comes a week after the action-cam specialist GoPro revealed a foldable drone of its own.

The two models are a similar price, but DJI's machine has the advantage of featuring obstacle-avoidance sensors.

The Mavic Pro can also fly further away from its operator and stay airborne for longer periods of time, according to its specifications.

Both companies failed to turn a profit in their most recent results.

DJI lost £11.4m over the course of 2015 , but GoPro was worse off with $233.7m (£179m) of losses for the nine months running until the end of June.
