wedivebc:So when you teach open water divers and you take all those eager beavers in the deep blue sea for the first time they are all able to survive the dive without help and they understand gas and decompression planning?
YES. If I drop dead of a heart attack in the middle of an OW dive one, I am confident that my students, in buddy teams, can end the dive safely. While my being there might provide a margine (for lack of a better term) they are there to get experience but they have already demonstrated the knowledge and skills. While I guide their planning...they do it.
Eventually we all encounter some level of "trust me" dives.
pediatron stated she has done several dives to 100+ ft and was comfortable at that depth. I say provided you are comfortable the blue hole might be a great experience. It may help to have someone more experienced such as a DM to supervise.
I tell my students to go into the water and don't be afraid to push the limit once in a while as long as you take baby steps.
130ft is only 15ft deeper than her deepest dive. That sounds like a baby step to me.
I'm not saying she shouldn't do it. Look at my first post. I listed a series of questions that I would ask myself. Maybe 130 is only 15 ft deeper but did she do the last dive or did she follow some one else who did it?
I don't need an answer. It's just something I think is relevant to her.
