It is easy to think of the drones that fly flying in the sky and taking objects on the ground when you think of drones. But the product I'm going to introduce is a drone flying over the sea, not the sky. It is an underwater drone called Titan made by a company called Geneinno.
The Geneinno Titan
The Geneinno Titan is capable of diving to depths of up to 150 meters and can withstand pressures up to 15 Bar. The body has a built-in 4K camera and the brightness of the headlight is 3000 lumens.
You must use a buoy with a cable to control the wafers. Connect the cable from the buoy to the drones so your tablet or smartphone can connect to WiFi. The controls are simple to operate and can be operated up to 150m deep.
