Do the requirements for a primary light for cavern diving differ from those of a primary light for cave diving?
I'm interested in getting my Cavern Diver certification and in the gear required it calls for a primary light and a backup. I understand that cave diving has specific requirements for primary lights but does that apply to cavern as well? Can I use my recreational dive lights for cavern? If so, is the a minimum lumen recommended or beam angle? What about the backup, should it be the same as the primary?
