In the past few months, we have covered a bunch of app controlled aquatic drones and underwater robots. The BW Space Pro is also worth a look. It comes with a 4K UHD camera that can also capture 12MP photos. Its image stabilization technology lets you capture crisp shots. It also has self-adjusting lighting system with dual front LED lights. This underwater robot is driven by 4 motors vertically and horizontally.
You can use the companion app to get a preview of all the action or control your BW Space Pro underwater. The drone can tilt upward/downward 45 degrees. It is rated down to 330ft. The battery lasts 4 hours on average.[where to get it]
