U-boat Worx C-Researcher 3 Submarine

You can use it for recreation, sure. But the U-boat Worx C-Researcher 3 Submarine isn't built for play — it's built for business. Scientific research, to be exact, and thanks to a huge number of available tools, it can collect samples and organisms, check water conditions, and create underwater maps, all while operating from a wide variety of vessels. It can also analyze the seabed, and thanks to new advancements in construction, it's the first transparent 3-person (one person, two passengers) submarine capable of diving to 1,700 meters, or well over one mile down, giving those aboard a view of the ocean most people only get to see on TV.
