Adventure Diving, West Des Moines

Lloyd Bridges had just discovered a host of sunken treasure on the ocean floor in Sea Hunt, and Randy Molnari had stars in his eyes. It didn't help that just weeks before, his elementary school class had visited Houston's marine-biology museum. If you were to tell this young, imaginative boy that he'd go on to earn certifications in shark feeding and technical diving, or that he'd explore some of the world's most exotic underwater locations, he'd believe you. Today, he and his team of carefully vetted instructors help novice and intermediate divers discover the underwater realm with lessons and trips for beginning or technical divers.

Classes include certifications in open-water diving and nitrox usage, and online lessons prepare computers for their own trips to the bottom of a lake. His staff works with police and fire rescue, and each member undergoes a two-year apprenticeship before they begin teaching. Once familiar with the techniques of scuba, clients can accompany staff on trips across the world, daring feats such as exploring shipwrecks in Lake Huron, cave diving in the Caribbean, or rescuing rubber duckies in the bathtub.
