I have been scolded by my Scuba Diving Instructor on this topic numerous times. As a Role model, he said, one must be wearing the complete Scuba diving equipment. So to those asking me, as a dive instructor, well, I have to teach you that yes, complete scuba dive equipment should always be with a snorkel.
Diving with a snorkel is a topic that generates mixed feelings among divers, both new and experienced. This comprehensive discussion aims to delve into the pros and cons of using a snorkel while diving, as well as various perspectives from different diving agencies and seasoned divers.
When it comes to using a snorkel, opinions are divided based on diver experience and the type of dive being performed. New divers, particularly those diving open circuit in the ocean, often find themselves using a considerable amount of their air supply just getting to the descent line from the boat. The nervousness and excitement can lead to heavy breathing, which depletes their air tank before the actual dive begins. In such cases, using a snorkel on the surface to save air can be beneficial. It allows divers to conserve their tank air for the actual underwater exploration.
However, as divers gain experience and confidence, the necessity of a snorkel diminishes. For technical dives or dives involving quick descents, snorkels can be cumbersome and interfere with equipment, such as rebreathers.
Technical divers often find that snorkels get in the way, potentially causing mask leaks or being uncomfortable to manage alongside other gear. Therefore, many experienced and technical divers prefer to dive without a snorkel.
Diver Training and Agency Perspectives:
Different diving agencies have varied approaches to teaching the use of snorkels. And PADI, as I mentioned at the top of this blog, encourages complete equipment at all times.
Some agencies end training sessions with divers at the surface with snorkels in their mouths, ready for potential rescues. RAID, a newer agency, even incorporates the skill of removing and replacing the snorkel as part of their open water training. This practice ensures that divers are comfortable handling their snorkels and understand how to use them effectively if needed.
Another interesting approach is to keep a collapsible snorkel in a pocket, which can be deployed if necessary. This method satisfies training requirements without the snorkel becoming a hindrance during the dive.
