Dive Time, Clarksville

For nearly three decades, Foster "Lee" Billings has spent at least part of his week underwater. The PADI-certified Master Trainer and owner of Dive Time shares his scuba experiences with local divers through classes and open-water dives. Whether students want to learn how to dive at night, explore a shipwreck, or take underwater photos, Dive Time's instructors make sure that each one gets training that's both safe and informative. The center is also a destination for more experienced divers, who can restock on equipment from the well-tended dive shop.
