The Personal Submarine costs $2M. The best part? Two people can go underwater in this vessel and it can go down up to 1,000 feet. It uses 3 horsepower vertical/translational thruster powered by electric batteries and controlled by a central joystick that according to the manufacturer allows for "precise positioning underwater".

the sphere is made up of 3 1/4 inch (8.25 centimeters) thick acrylic and has a diameter of 56 3/4 inches (1.44 meters). Its got four external 150,watts quart halogen lamps to light the way in the deep blue sea. And its got enough power to take video and photographs as well. Not bad! [Hammacher Schlemmer via Uncrate]
