Dives to less than 20 ft are categorized as what?

Dives to less than 20 feet are typically categorized as shallow dives. This classification is important in diving because shallow dives are generally associated with various conditions and safety protocols that differ from deeper dives. Shallow diving often involves less decompression risk, reduced nitrogen absorption, and simpler planning compared to deeper dives.

The other terms, such as deep dives or technical dives, refer to dives that involve greater depths or specialized skills and equipment, respectively. The phrase "6m/20ft dives" could imply a technical measurement but is not a commonly used term in diving classifications. Therefore, the appropriate categorization for dives under 20 feet is shallow dives, highlighting their unique characteristics and the simplified procedures that come with them.
