The oceans of the world are dark and full of terrors. Which is why you can’t go down there without protection. And also because of the lack of breathable oxygen and pressure issues but the dark terror thing is also important. If you want to explore the ocean’s bottom get yourself the Self Propelled Aquanaut’s Suit.
Sure you can get normal scuba gear but that’s a pretty lame option when you could turn yourself into a Big Daddy and walk the ocean floor like you’re patrolling the madness overrun streets of Rapture. You know you want to do that.
This thing comes with a 50 hour life support system. You could be trapped down in the bottom on the ocean for two days without worrying about running out of air. But food, water, and the ever present threat of madness would likely be an issue. Don’t worry though, it also has a wireless communication system that will let you call for help if you need. Explore sunken ships, the ocean’s floor, and the caves of slumbering elder gods in this suit. The Self Propelled Aquanaut’s Suit is $825,000.
