About this course
4-Day Master Course
AIDA Level 4, also known as Assistant Instructor level, is the most advanced non-professional freediving certification.
This course familiarizes students with techniques, knowledge, and safety procedures for deep freediving that go beyond recreational freediving. New techniques include FRC diving, mouth-fill equalization, and packing. Skills are developed within these categories: Static Apnea, Dynamic Apnea, Constant Weight, Free Immersion, and Variable Weight. In addition to in-water skills, this course introduces full-body warm-ups and stretching, specific stretching of breathing muscles, and training concepts and diet that benefit the freediver and help shape their development as a diver. You'll also be introduced to packing and reverse packing, mainly within vital capacity, as part of the dry lessons.
An important set of skills concerns managing open-water equipment: using appropriate knots and braiding techniques, setting the depth on the dive line, constructing a safe bottom weight from a weight belt and diving leads, and safely handling additional equipment such as the bottom plate, torches, and lanyards.
One of the purposes of this course is to prepare successful candidates for the role of Assistant Instructor. That role includes leading appropriate warm-up sessions for confined- and open-water freediving and supervising students of all course levels during their confined- or open-water sessions.
