I am now an open-water certified SCUBA diver, how often should I dive?
The answer: the more the merrier. Diving is like a lot of other sports – The more you practice, the better you become at diving. The better you become at diving, the more your comfort level increases. The more comfortable you become, the better diver you become. Plus, you want to keep up with the skills you learned in class.
One of the most important skills a diver has is being a good dive buddy to your dive partner. Unless you are a solo certified diver, you need a dive buddy. This is a safety issue as you may be required to assist your buddy in times of need (i.e. air sharing, emergency accident, or entanglement, etc).
The more you dive and the more your comfort level increases, the better all-around diver you will be.
