I will be diving in a few weeks with totally new divers, who are friends. Normally, I either dive solo or dive with my kids. After reading some of the posts, it seems the buddy is legally responsible for the well being of the other diver. I am open 1 certified, and don't plan on becoming a DM , or instructor. If problems arise, I have no problem lending assistance. I am more than capable of CPR, and dragging them back in if need be. So I ask, is it better to just make them dive with a group on the boat and not worry about it, or have them join me? . I will be in Cayman, and don't know if their laws are different. I plan on the southeast, south wall CYB, where the top of the reef is only about 45-50 feet, which should be safe. Cheers
