Similar to tickling a bear without losing an arm, the art of breathing underwater requires years of practice and dedication. Introduce your lungs to aqueous awareness with today's Groupon to Scuba-Fun in Key Largo. Choose between the following options:

• For $69, you get a Discover Scuba Diving adventure with a lagoon dive and a DVD of photos (a $149 value).
• For $169, you get a PADI Scuba Diver course and basic certification course (a $339 value).

During the Discover Scuba lesson, undersea explorers master basic scuba concepts and skills under the close supervision of a certified instructor. After studying a 30-minute tutorial video and watching the blooper reel from Waterworld, pupils enter the shallows for a gear demo. Once they're accustomed to their amphibious accessories, students dive up to 25 feet in Scuba-Fun's ocean lagoon with the chance to peep a variety of tropical fish, including barracuda, snapper, and grouper. Upon completion of their subaqueous excursion, participants will receive a certificate and DVD with photos from the adventure. All diving equipment is included, but students should bring along their own swimsuit, towel, sunscreen, and seahorse saddle.

Those seeking lifelong scuba certification should enroll in the PADI Scuba Diver course. Prior to their lessons, divers receive a PADI Open Water Diver Manual to study and quizzes, which they'll review with their teacher on the day of the dive. Participants then spend time observing their instructor's diving skills before practicing for two of their own 30-foot open-water dives. Upon completion of their submersions, students may obtain the PADI certification, entitling them to scuba dive anywhere in the world with a professional diver or unprofessional dolphin. Though the scuba gear is provided in this course, patrons will need to provide their own swimsuit, towel, sunscreen, mask, fins, and snorkel (available for rental or purchase).
