The friendly submerged seafarers at Ocean Enterprises have served earthbound San Diego vertebrates for more than 31 years. The center's introductory scuba diving lesson welcomes aspirant underwater aspirators to learn the fundamentals of diving within the warm, safe confines of the facility's pool. After meeting with one of the passionate, certified instructors, you'll learn about the basics of the dive before getting acquainted with the provided equipment, including the buoyancy control device, regulator, mask, fins, and snorkel. Then, after a few minutes of aqueous immersion, you'll develop a newfound affinity for your artificial gills, filled with vigor to discover shipwrecks, reefs, buffalo nickels, and water buffalo with dewy, suspicious eyes.
