Ortega Mk. 1C Personal Submarine

At first glance, the Ortega Mk. 1C Personal Submarine looks as much like a boat as it does a submarine. And with good reason. Its pair of high-powered electric motors are designed to work both over and under the water. The on-board breathing apparatuses let you dive over 300 feet under the surface, HUD navigation keeps you pointed in the right direction, and a range of 80 nautical miles lets you explore more than just the waters next to port.
