Wild Chronicles: Annals of Risk - Underwater Cave Diving

In this week's Wild Chronicles segment, Boyd shares the story of his own experiences diving in underwater caves. He says that in open water scuba diving, you're able to let your air tank go down to nearly empty, although you're not supposed to. The repercussions of running out of air, or even losing you way in an underwater cave system, are much more severe than risking decompression sickness from surfacing too quickly in open water.
