The stakes are high for GoPro heading into the final quarter of 2016 - it needs its newest lines of micro cameras and its drone to be a hit come Christmas time.

GoPro were pioneers in the market for durable, wide-lens, high definition cameras, but sales have lagged since 2014.

The launch of its Karma Drone - the brand's first major release outside of its core camera range - hasn't gone smoothly and has already been delayed by six months.

While drones and GoPros have been a natural mix and created a new sub-genre of aerial photography, the company will need to compete with established players in the increasingly crowded drone field.

The device's stabiliser can be used both on the drone and on its own to operate like a mini steady-cam arm grip.

But it will come at a pretty hefty price - the drone unit without a camera will start at $799 when it goes on sale next month. Bundles with a GoPro start at $999.

Investors had a positive reaction to the launch

The company has also unveiled a Hero5 Black edition with a touchscreen LCD display, and the smaller Hero5 Session. Both cameras are waterproof without requiring an additional case and feature voice control.

The company went public in 2014 but has struggled to get investors excited about the future of the firm.

In its second quarter revenues fell by 47% to $220.7m.

The durability of the cameras means that users have been slow to upgrade their gear.

GoPro has also acquired two film editing apps, to help users to clip their footage - using their engines it has developed its own editing programme, Quik.
