Image of 13 from The CQ-2 twin seater personal submarine

The 2-seater personal submarine was recently debuted by C-Quester at Monte Carlo after the success of their earlier single-seater. Fully electric, the CQ-2 keeps cabin pressure at one atmosphere, meaning you can travel up and down with no decompression issues. A charge will last you 2 1/2 hours underwater, and there’s a bunch of safety systems including enough air for 36 hours in the case of an emergency. A four-seater model is expected soon.
