STEPDiver - Book 3 of 3 This third and final book, STEPDiver, covers the more advanced skills of buoyancy control, breath control, air management, swim technique (Frog kick), emergency techniques, and dive planning. These topics can be practiced at shallow depths of 3-5 meters, 10-17 feet, to build up solid experience. It is perfect for older children, from age 10 and up, who have already completed the first 2 books. It provides an extremely solid knowledge and skills base to eventually progress to the Junior Open Water Diver courses at an older age. Experience Before Depth: Where adventure begins, and learning never ends. Perfect for kids, but guaranteed fun for the whole family! EXPERIENCE BEFORE DEPTH - the training The books have been reviewed by NAUI, and align with corresponding training courses and certifications available on NAUI’s website. With practice, experience, and fun in shallow depths, kids and teens can seamlessly transition their newfound skills into natural behaviors and reactions underwater. As they grow and mature, they can progress year-over-year to deeper dives and lay a foundation of experience to take onto their SCUBA certification at an older age.
