Living in Miami and not taking advantage of the ocean is like living in Vegas and refusing to gamble, residing in Phoenix and forgoing Mexican food, or being lactose intolerant in Wisconsin: It just ain't right. That's why Underwater Unlimited has been prepping local divers for aquatic adventures since Charlie Matthews opened it in 1964, and it's still going strong with more than 24,000 certifications. Charlie Jr. now runs the shop with his beyond-friendly team, whose service technicians and dive instructors go above and beyond. Sign up for their training and you'll get to know the staff — they're not simply going to hand over a certificate. Just ask the University of Miami Scuba Club, which uses UU for its members' certification. Tuition for Open Water Certification starts at $150, with personal, private, or concierge classes from $300 to $500 and affordable specialty courses for continuing education as low as $55 per class. Drop by the dive shop for discount equipment packages and service specials, and once you're certified and geared up, test your newly acquired skills on one of the shop's many dive trips, which go anywhere from West Palm Beach to Key West to Crystal River for dives alongside hundreds of manatees. Don't you want to see those sea cows up close? Get that certification already.
