Breathing underwater, like eating fireworks, constructing a monument, and getting married, should only be attempted if you're confident you can do it. Muster up the confidence with today's Groupon: for $169, you get an open-water certification class plus all PADI-certified textbook materials (a $349 value) at Scuba Utah, located on East Fort Union Boulevard.

The diving gurus at this PADI five-star instructor-development center train fledgling underwater explorers and practiced deep-sea divers alike with an array of diving courses. The open-water diver course unlocks a whole new closet of watery wonders by equipping students with the skills, documentation, and gills for safe subsurface swimming. Pupils show up ready to learn the ways of the scuba via classroom study and an on-site pool. The training can be completed during a two-week session that meets twice a week or over the course of a single weekend. Following the completion of controlled lessons, merpersons will venture to Homestead Resort in Midway for two days of marine acclimation in the Crater.

Although this Groupon includes all PADI-certification materials ($128), open-water-dive costs are not included ($22 each time for total of $44) nor is personal gear such as a mask, fins, and snorkel. Scuba Utah provides all other diving gear (BCD, regulator, weights, and tanks), freeing equipment-less divers from their recurring nightmares of trying to siphon off oxygen from empty sea turtles.
