I've found that there are many things that can loosen and move my mask strap - fins kicking me, air in my hood, scooter prop-wash, and I'm sure there are others I've yet to experience. I've had a few incidents where my mask suddenly just came off and I had the unexpected cold-smack in the face with water up the nose. I can see how losing a mask could easily cause someone to "hit the elevator button" or bolt for the surface.Pez7378 wrote:I'm sure there are different schools of thought. Personally, I would want it both ways. I would want to trust my buddy to manage things and get me to the surface safely by using touch contact. I would also want contact with the line, simply for peace of mind, providing that there was a line to have contact with.
Thanks for sharing your experience Howard, it's given me some things to think (worry?) about.
In massive quantities its not very common and where it is present its generally a known deal so you can skip that dive. Its basically not found in wrecks at all. (plenty of other nasties but not H2S)Nwbrewer wrote:In case I needed another reason to stay out of caves.....CaptnJack wrote: She was fine after a day.

Unfortunately reason number one is a small omount of claustriphobia. I don't see myself going in any caves or wreck anytime soon. Good to know about the Hydrogen sulfide though. Do folks diving these area use FFM's to try and combat the nasties? or just deal with it? Sorry to hijack a perfectly good thread Howard.CaptnJack wrote:In massive quantities its not very common and where it is present its generally a known deal so you can skip that dive.

That would be one of many good reasons to stay out!Nwbrewer wrote: Unfortunately reason number one is a small omount of claustriphobia. I don't see myself going in any caves or wreck anytime soon.

Commerical deco = chamber. They don't really do in-water deco. Boydski was a commercial diver hopefully he can chime in.Grateful Diver wrote:Hmmm ... good point ... how DO FFM folks do things like deco switches? I mean, since they're used for a lot of commercial and scientific dives, it stands to reason there'd be some deco involved, right?
Do their regs come with "wet plugs"?

You are double correct Lynne - We do these drills in hopes if we need them in actual technical diving we will be best prepared, and in a Wreck we must follow the line out, so in a no mask line exit scenario there is a good chance the sightless diver will need to have his or her hand led to the line because there will be no room through the doorways and corridors to be guided by touch.LCF wrote:Oh, I don't question the idea that a single diver should be able to follow a line. I just thought it would be odd to have one sighted diver, but put the maskless diver on the line, since it slows the exit significantly. I would think that would be true in a wreck as well. But, of course, we sometimes do things in drills when we wouldn't necessarily do them that way in real life.
Wreck divers make better cave divers. Cave divers make better wreck divers.mattwave wrote: Why the point has always been raised is a well trained Cave Diver really trained well for Wreck Penetration, or vise versa?
