$159 for Open-Water Certification Referral Course with Gear and Educational Materials at Pirates Cove Scuba ($324 Value)

Breathing underwater--like eating fireworks, constructing a monument, and getting married--should only be attempted if you're confident you can do it. This Groupon gives you all the skills you need to mingle with the mermaids.

$159 for an Open-Water Certification Referral Course ($324 Total Value)

• Course admission (a $199 value)
• Rental mask, fins, and snorkel (a $50 value)
• Educational materials (a $75 value)

Open-water certification referral classes commence with a three- to four-hour group review and testing period on educational materials each student must pore over prior to class. Trainees then strap on masks, fins, snorkels, and dive gear to practice breathing underwater and communicating by exhaling thought bubbles during two three- to four-hour pool sessions. Burgeoning submergers graduate to full scubateer status on completion of four open-water dives that are not included in this Groupon but may be completed at Pirates Cove Scuba at an additional charge or referred out to other facilities. Partakers should survey Pirates Cove Scuba's class schedule to pinpoint a suitable session.
