Much of the ocean remains a mystery, just like the unmapped caves of Borneo and the appeal of family road trips. Explore the unknown with today's Groupon: for $15, you get a Discover Scuba Diving lesson at Divers' Supply Indy's Indy or Indy West locations (a $30 value).

Divers' Supply Indy supplies devoted divers of all skill levels with continuing education and quality equipment. Discover Scuba Diving lessons encourage steadfast swimmers to try out scuba diving and underwater respiration before plunging into the rigors of a certification course. Figure out the fundamentals of scuba equipment in shallow water, allowing for maximum safety and comfort while fiddling with gauges, masks, and car-stereo knobs. Class participants shake hands and talk about the weather while experiencing the new sensation of breathing underwater. Divers' Supply provides all necessary scuba equipment, including basics such as a mask and fins, as well as a buoyancy-compensating jacket with scuba tank, scuba regulator, and instruments to monitor depth, check air supply, and locate sea-life jam sessions. The staff teaches courses, which accommodate between 10 and 20 students, in both indoor and outdoor pools.
