Buy the DJI Spark on Amazon for $389
Perhaps your dad is more into flying things, in which case, a drone is the perfect present. The DJI Spark Drone isn't the highest-end drone out there, but it's still super functional and comes at a fraction of the cost of some of DJI's other drones.
The drone itself features a 2-axis stabilized gimbal, along with smart tech like obstacle detection, meaning that it should stay safe and sound as long as it's flown pretty responsibly. It has a battery life of up to 16 minutes of flying time, which doesn't sound like much, but isn't bad considering the price tag and overall size. It can also fly at up to 31 miles per hour, which again, is pretty decent for a device in this price range. It's also great for taking selfies, family photos, and any other photos that you might want to be in, instead of taking the actual photo.
