Here is an underwater robot with a fully integrated 4K UHD camera that lets you capture all the action in any body of water. The PowerRay robot has a base station with a 164 waterproof tether and a battery that lasts up to 4 hours. The transmitter connects to the base station wirelessly to allow you to operate the vehicle, adjust lighting, and change speed.
The robot has a sonar fish finder and can dive to a depth of 30 meters. You can even use it with FPV goggles to get a more immersive experience.
