Overhead Environments

Divers are a curious bunch, and while most are happy to explore the open ocean, others are drawn to the thrill of exploring overhead environments. These intrepid explorers venture into undersea caves, abandoned mines, and shipwrecks, where direct access to the surface is not always possible. If you’re interested in this type of exploration, NAUI offers a variety of training programs to help you safely and confidently navigate overhead environments. Contact your local NAUI Instructor to learn more.
