Breathing underwater, like eating fireworks, constructing a monument, and getting married, should only be attempted if you're confident you can do it. Today's Groupon gives you all the skills you need to mingle with the mermaids: for $189, you get a scuba-certification package at Mac’s Sports, valid in Clearwater, and Tampa (a $379.90 value). The package includes:

• Course tuition (a $159.95 value)
• Student training kit that includes a certification card, logbook, and registration fees (a $99.95 value)
• Two open-water dives (a $60 value each)
  
  

Divers will need to provide their own mask, fins, snorkel, weights, and weight belt or rent them from Mac's at a cost of $20 per night.

The veteran aquatic trainers at Mac’s teach new divers to safely stay underwater using scuba gear. Students will matriculate in Mac’s open-water-diving program, learning the basics of submerged exploration in both academic sessions on land and flippers-on sessions in the heated indoor pool. Resources and materials included in the training kit bolster brains with the ins and outs of maneuvering and communicating underwater, whereas the certification card lends credibility to any attempts to retrieve coins from the bottom of a fountain. Before the completion of the program, students will venture out to Weeki Wachee Springs State Park for two open-water dives, reaching depths up to 40 feet while enjoying warm temperatures, 200 feet of visibility, and the ever-present chance of swimming into a snoozing eagle on vacation from flying. Call ahead to reserve a spot in class.
