Do I need to visit the store before the program starts?

Yes! in fact the Professional Association of Diving instructors require it.
Come to the store 7 – 14 days before class begins to do the orientation. You will be sizing the instructional gear such as wetsuits and BCs that will be used in the pool. You will be filling out the medical release and liability in person (cannot be done remotely or last minute). Personal gear needs to be selected if needed. There is a lot to be done before a PADI scuba class begins and it cannot be done remotely due to standards set fourth by the scuba training agency. You should receive a welcome e-mail with instructions that explain in detail the steps required to be ready for your upcoming program.
