The automatically maintained neutral buoyancy means that all maneuvering can be done using the thruster motors. These two motors can be directed up and down to cause descent and ascent. Their speeds are variable and they can be independently reversed, allowing the pilot to turn, hover, move forward and backward, or spin on the spot. The balanced pressure hull allows large, flat windows to be used because they don't have to withstand much pressure difference. Each occupant has unobstructed views in all directions, including straight down, which is where much of the marine scenery and activity is located.
Flat windows minimize the natural distortion that occurs when water and air meet.
These are used for forward looking windows to permit accurate visual navigation. The dome shaped side windows exploit the distortion effect and provide a wide angle lens effect allowing occupants to see a larger vista. The SportSub design keeps light from above out of the cockpit so reflection of interior objects is kept to a minimum. The ambient pressure principle also allows easy exiting of the sub without using a lockout chamber. This allows passengers to exit the sub and walk around on the sea floor.
