Overview

Cruise Sub puts groups of five to eleven guests inside twin acrylic spheres for a fully immersive 360° dive experience, with revolving seating platforms that let every passenger rotate toward the action.

Eight vectored thrusters give Cruise Sub true omni-directional movement — forward, reverse, sideways, up and down — for precise positioning over reefs and wrecks.

Since its 2018 introduction, more than fifteen Cruise Sub configurations have been sold and deployed worldwide, and the Cruise Sub 7–1140 holds the record for the highest-capacity, deepest-diving submersible ever certified.
