Designed with completely dry sealed cabin, Neptune MM2 is a two-seater sport micro submersible. Neptune MM2 can reach a dive depth of 750ft, with full life support. It includes a highly secured and monitored environment, with powerful oxygen refill system and CO2 scrubbing. Neptune MM2 can achieve speed of 12 knots under the water. Balance is controlled by a state of the art comprehensive onboard, multi point exterior pressure analysis and adjustment application, which constantly re-adjusts to aquatic motion conditions using the thrusters and the large dual section steering/braking tailfin. Tsimenzin’s sub is unfortunately still a concept.
