STEPUndersea - Book 2 of 3 This second book, STEPUndersea, covers the key safety and skills required to progress from the surface to the underwater. It covers equalization, mask clearing, neutral buoyancy, decent, and slow, controlled ascents. These topics can be practiced at very shallow depths of 1-2 meters, 3-7 feet, to build up solid experience. It is perfect for children, ages 8 and up, who have already built up the comfort, calm behaviors, and initial experience with the first book. It builds the right safety focus, behaviors, and engrained reactions to eventually progress to deeper water and more advanced buoyancy and SCUBA skills at an older age with the follow up book. 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.
