After the introduction of Karma, Adam Lisberg, director of communications at DJI, responded by saying: “Originally, Dajiang welcomes all competitors. We have unparalleled experience in drone flight and handheld stabilization technology. They have unparalleled experience. Trying to catch up."

Here we will compare the two products.

Portability: Karma can be packed into a backpack

Compared with its predecessor, DJI Phantom 4 is much smaller, but it takes up more space than Karma. If the GoPro drone is folded, the size of the Phantom 4 is twice that of Karma.

In the standard configuration, Karma is equipped with a backpack. If you purchase a drone, you need to spend an extra $200 to buy a backpack. We can pack a drone, a controller, a stable embedded Karma Grip (a handle that can be connected to the drone's head), a camera, and a charger.

The Phantom 4 is relatively cumbersome and it is not particularly easy to put in a backpack.

Versatility: More than just a drone

The Karma drone is equipped with the battery-operated Karma Grip, which is a stabilizer that can be used to control the camera and is easy to use by hand; we can also connect the Karma Grip to the accessories, as long as the accessories are compatible with the GoPro product. It can be connected to the head of the drone without manual operation.

DJI also launched Osmo, which integrates a 4K camera and is priced at US$560.

Simplicity: You can fly in seconds

Using GoPro Karma is easy. Open the propeller arm and landing gear, you can use remote control drone flight, the remote control looks a bit like a video game controller, which has a built-in display.

Phantom 4 needs to connect the smart phone and tablet to the remote control before it can fly.

Cheap: Only half the price of Phantom 4

Even with the addition of GoPro's latest Hero 5 4K action camera, the total price of the Karma kit is only US$1,099, while the DJI Phantom 4 needs about US$2,000.

Frankly speaking, the GoPro drone lacks two major functions: First, the anti-collision function, the second is the "follow me" mode, which can track the user's actions.

GoPro founder Woodman stated that he does not think these advanced features are necessary. I do not agree with this. For example, when I rushed down the hill with a snowboard, I could not control the drone without these functions. Because of this, I will not recommend GoPro drones for the time being. I am convinced that GoPro will add these advanced features in the next generation of products, or add more powerful drones to the product line.

Mavic: Dajiang's counterattack

Dajiang is also preparing to issue the next generation of UAVs. Its name is Mavic, and soon Dajiang will hold a press conference in New York.

According to the "accidentally" leaked information of the DJI website, Mavic is a collapsible drone that can directly challenge the GoPro drones. Like its competitors, Mavic is equally pocket-sized and equally inexpensive if it increases crashworthiness. And the "follow me" feature is even more powerful. Phantom 4 has these two functions.
