Your Sea Trek helmet dive explores Cozumel's pristine underwater world. An astronaut-style helmet keeps your head and shoulders dry the entire dive, and it provides a continuous air supply. Your experienced guide/instructor will provide a briefing on the equipment, safety, and communication before heading to the Sea Trek platform. Explore beautiful coral formations and sea critters of all shapes and sizes. A half-hour later, relax at the beach and swap your helmet for the complimentary snorkeling equipment.
