Hate swimming/diving but still want to experience what the underwater world has to offer? Please keep in mind that this personal submarine won’t fit in your carry on luggage.
This is the two-person submersible that can descend to a depth of 1,000′. Providing access to underwater features such as coral reefs, shipwrecks, and the sea floor, a completely transparent, climate-controlled 3 1/4"-thick acrylic pressure sphere keeps explorers safe while dipping even into the mesopelagic zone, offering a chance to see exotic, bioluminescent species such as lanternfish. With a maximum speed of three knots, it is powered by a 120- and 24-volt battery bank that provide up to six hours of continuous undersea adventure.
