RTH, or Return To Home, is a technology that allows your drone to return automatically with its own vision system or GPS record. It usually appears as a "RTH" button that you just press and the drone will return home. More significantly, it allows the drone to automatically switch to RTH mode and return to the takeoff point in case of emergency, such as low battery, remote control signal interruption, image transmission signal loss, etc. Most drones have this feature. After all, no one wants to spend time looking for a drone unless it's for a special purpose. Here is the best RTH drone for you, so you don't worry about it getting lost anymore.
