This is probably one of the most unusual dive sites on the planet. You can explore an abandoned World War II missile silo that's completely flooded. Host Greg Martin explores the site with UnderSea Adventure's owner, David Bruns.

Louis Prezelin joined the Cousteau Expeditions in 1968, first as a diver on camera in the early shows of the series, "The Undersea World of Jacques Cousteau" and then as assistant cameraman on the legendary "Calypso."  Capture some of the breathtaking underwater adventures by tuning in through the eyes of Prezelin.

NAUI Technical Diver Harvey Morash from Nova Scotia Louisbourg Scuba discusses his experience with the History Channel's The Curse of Oak Island and his search for the bottom of the mysterious BoreHole 10X. Stirred-up sediment, metals, and leftover green dye makes for a murky hunt and may have slimmed his success for the find.  The search for Borehole 10x is a quest to find riches within Oak Island, a small island off the shore of Nova Scotia, Canada.

Did he get to the shaft that leads to an underground cavernous treasure trove—only 27 inches wide? Tune in, and get ready for a treasure hunt! THE CURSE OF OAK ISLAND airs on History Channel on Tuesday nights at 9/8c.

Many dive industry manufacturers are now getting into the realm of technical scuba diving and expanding lines of tech gear, while dive shops are even now offering varied tech scuba certifications. 

Greg Martin discusses technical diving and streamline gear with Tim O'Leary, president of American Diving Marine Salvage and chairman of both NAUI's technical training and rebreather advisory boards. Listen in on information regarding the changes of tech diving then versus tech diving now!

It's a long road to success for dive shop owners.

"If you want to make a million dollars, you need to start with two." Tune in as we interview Al Jeffrey, with Florida's #ScubaQuest dive centers, about the profitability of the local dive shop and the relationship with students.

Tune in as we get an in-depth interview with Eugene "Rod" Roddenberry, son of #StarTrek creator, Gene Roddenberry, to discuss Roddenberry Adventures and his initial love for diving. "For a long time, the worlds of Star Trek and scuba diving seemed to go hand-in-hand...exploring strange, new worlds, seeking out alien life...well that is scuba diving; floating weightless in space..." Roddenberry Adventures has been affiliated with #NAUI since its beginning and also has a partnership with NAUI's NAUIGreenDiver Initiative.

Divers have been making a living in many different ways over the years.  Greg chats with #NAUI certified divers Dave Stone and Clint Roberts (the Dreadknot's), from the History Channel's reality TV show Ax Men, as they talk about their career as part of the Underwater Log Recovery Specialist Team. The job is considered the most dangerous job in the world because it combines underwater diving (commercial) with logging. "Everything down there...I swear...is out to kill you. Tree limbs, ropes, anchors, gators, snakes, snapping turtles…" "Think of Dr. Seuss' worst nightmare; that's where we hangout, everyday." For more, tune in every Sunday at 9 p.m. on the History Channel.

Imagine an underwater experience free of bubbles and equipment and in one breath of air. Freediving has become its own culture and lifestyle, aside from scuba diving.
