“This is what the dive community has needed for years.”

Farmingdale Aquatic Center

We are happy to share with you the exciting news that the Long Island dive community now has something it has needed for a long time. We now have access to a beautiful pool at the new Farmingdale Aquatic Center. This is a great pool that we can use to keep our skills up, try out new equipment, practice our underwater photography, work with our dive buddy so our diving goes smoothly, the list goes on and on.

These pool sessions are available to all certified divers. These pool sessions are available to certified/insured instructors with their student(s). These pool sessions are available to the dive community during our off season, so we can keep our skills at their best. These sessions are available to divers so they will be ready for the great dive adventure they have planned for this Winter. As you can see this is great for the dive community and we hope we can make it an ongoing program.

The setup is simple - for $100 a diver will get 3 two hour pool sessions at the new Aquatic Center. Everyone in the pool has to be registered with Farmingdale Continuing Education.
