Ken Larsen's web site - Drone videos
In September 2017 my son Kevin visited me. He brought with him a drone that he uses in his videography business in Connecticut. Here are some videos:
Kevin's drone is a DJI Mavic Pro. It sells on Amazon for $ 985. It needs a mobile device to serve as its display. Range= 4 miles Maximum altitude is 400 feet per FAA restrictions.
DJI is a Chinese company.
Kevin recommends this drone that comes with its own display: Wingsland Scarlet Minivet Quadcopter. Cost= $ 350. Range: 1800 feet. (1/3 of a mile)
Kevin also brought with him a GoPro Hero 4 Black (cost= $ 290). He prefers it over the Hero 5 (cost= $ 390) because of the cost, and it's better if needed to take underwater shots.
There's a GoPro Hero 6 Black. Its cost is $ 500.
