We don't know about you, but we take our personal safety rather seriously. We wear a helmet when we Segway to work in the morning, swaddle our children in cheesecloth and bubble wrap — holes for eyes, nose, and mouth, of course — and are terrified by revolving doors. So when it comes to exploring the mysterious, gaping maw of the Atlantic Ocean, we refuse to let some slack-jawed scuba instructor hold our life in his Corona-swilling hands. We shell out for the best, and the best in this case is Grove Scuba. Co-owner Bill Lamp'l is the only person in Miami who can actually train you to become a dive instructor. He's also an underwater photography fiend. Grove Scuba is a bit pricier than some other dive shops around town, but it makes up for the expense with cheap underwater camera rentals and a mind-blowing 57 dive locations in Miami and Key Largo. They include dozens of wrecks, reefs, and a statue of Jesus. Open-water scuba certification costs $475, but dive novices can try a two-dive intro course for $195. If you decide to get certified, those dives count toward it.
