I agree with everything you have said here. For quarry diving I always bring a
couple of 80s with air and/or light mix with me as well as the deco bottles,, in case I desire to save my backgas or need to power my booster. The issue at a quarry is that below the thermocline the temp is about 42...
Come to the midwest and I would be happy to take you quarry
diving. You would then notice that a quarry is much more
benign than the ocean. You don't have to worry about:
getting blown out to sea, tide, surge, current, dangerous
animals, falling to thousands of feet deep,salt eating up
Your assumption is flawed. This insructor is not DSAT savy.
He thought it ,,,Jr. high level... But we all dive at our
level of comfort and he allowed me to. Because there are
divers that will be more advanced and more seasonsed
than you or I will EVER be that have died because they
So why did you bring it up? .So I'm forced to not have redunancy on my stage. Thanks.Why do you insist it is non-redundant? Oh yeah, once again
a restriction you want to lay on me.
Wild guess I guess. Sure, say don't do
this , don't do that because it's not as safe as I do it. Here
Do you think this procedure goes against the manual? Do you think
I have only had one instructor covering one agency? Do you think
I havn't been honest to one diver that has contacted me on PM?
You boys are likely as one writer said, "fanatics".
I explained this to my tech instructor,,, his advice, I can save my backgas if I desire
and that is not dangerous. It is not a problem to have a side bottle with a lower MOD than my backgas. If your not comfortable breathing your side bottles you shouldn't take em. But then, he dives a...
Say, your backgas has 32%. You go to the local quarry, max depth 110 ft. But, darn
it is closed. You go somewhere else, 140 ft. depth, but they have no gas for you. Well, can you still go to the bottom safely. Sure, multiple bottles. Is it ideal, nope.
Is it doable and safe, I would submit...
I am sure you are aware that some people have gotten bent even though
they stayed within all the computer parameters. There are some divers
that add cushion to their dive even though "they don't need it". I never
said this is the safest way. It is practical if your somewhere where you can't...
30 ft. would get you to the MOD of the backgas. If the side bottle popped
you could easily get there. Or go on the pony,, or to your buddy. If this
is uncomfortable for you,,, then say no. Dive at your level of comfort.
I'm not stopping you or yanking your chain about it. The original point...
You say we need fully redundant gas supplies,, doesn't that mean enough
gas to get me to the surface safely? Why wouldn't a pony do that? Why
can I now not have a buddy? Why can I now not ascend a little, at the bottom
of this quarry is nothing to hang myself up on. Why do you restrict me...
:Don't people dive singles all the time yet still have redundancy? Like, backup bottles,other divers, the option to ascend a little? Do the bottles have to be
manifolded to be considered redundant? What about sidemount divers? Their bottles
are not manifolded. Kal
You seem to think that breathing a stage at the bottom of a quarry means there is no redundance, this is not so. If I am restricted to only breathing my backgas in a quarry then I find that too restrictive. Sorry the term 'restrictive' pushed a button ( I did not mean it to be mean spirited, I...
Well, I didn't say your def does not cover rec cave.
I didn't say the diver is neccessarily carrying the O2.
I appreciate your restrictive diving, good for you.
But to assume if someone doesn't maintain your
tight practices is not a tech diver is likely not
true. Obviously you feel the...
