BC would probably have to go first and pass down to the younger!My daughters, on the other hand had their gear before the class. They did their pool sessions and all checkout dives with their own regulator, BC, and computer. Used the shops tanks, though as they were included and the shop had smaller tanks available. They also used the shops wetsuits. The girls were still growing like weeds, so I wanted to wait a bit on their wetsuits.
BP/W could be another option in few yrs time.
