The ability to propel oneself through water is not strictly necessary for participating in surface-level aquatic observation using a breathing tube and mask. Individuals can experience the underwater world near the surface even without proficiency in swimming. This activity generally involves floating at the surface and observing marine life below.
The appeal of this activity lies in its accessibility to a wider range of individuals, including those with physical limitations or a fear of deep water. It allows for appreciation of underwater ecosystems without requiring advanced swimming skills. Historically, simplified equipment and designated shallow-water areas have facilitated participation for non-swimmers.
