Using A Long Hose Isn't Just For Tech Divers

[jeffinhburg]

Geez, I didn't mean to create fights over long hoses for newbies or the various hose sizes. I really just wanted some insight as to the considerations betweem then and how they would be used correctly, so that I could at least know enough to ask for the training that might be most useful for me. Sometimes it's tough to communicate what it is you are looking for until you know enough to describe it. I wouldn't actually try to DO it without instruction - just need to ascertain what instruction I want, and hopefully learn a little.

Some more probably stupid questions -

Based on the routing descriptions of the 5 ft hoses, I'm guessing that a snorkel is not supposed to go with that setup, either? I'm also guessing that, if that is the case, the drawbacks may outweigh advantages for me because I usually have long surface swims to get to the dive sites?

Is there any class (and this is not to start an agency fight - just what is very conveniently available here) with SSI or PADI where safe use of long hoses is likely to be taught or where the instructors are likely to be able and willing to teach it? Should I ask about it during a wreck diving class, for instance, where I would imagine a long hose would be most useful if needed?

Thanks.

I teach OOA on the required open water dives, at 20' with 20' of water below us, that's in addition to the pool sessions. I am not affiliated with any dive shop, NAUI allows it for instructors. Look, I just don't over teach... everything in due time...

Swim on your back and you don't need a snorkle. Aside from the evil, vilve cult organization - I think only NAUI with their new tech stuff teaches long long hoses?

It's pretty easy to learn to deploy and stow a long hose - just practice on dry land first. There are pics/links in the *eck* DIR forum here on SB.

Don't worry about it....these are the fun threads

Can't use it with a snorkle because of the hose lying on your neck. (it might pull off your mask when you deploy the hose for an OOA)

DIR-F teachs it. Finding a mentor may help (if they lean to the tech side)

Rock bottom = amount of gas required by two divers to go from the bottom to the surface in an emergency gas sharing situation (making all nec stops).

We give ourselves 1 minute for an emergency on the bottom (this can be tweaked, if you want 2, use 2)

1 minute for each 30' on the way up

we'll include min deco (1min at 30, 1 min at 20, 1 min at 10) - if you don't want to do this - don't!

Assume 1 cu' SAC

we then need to convert out sac to average atmospheres for the dive

Here's an example - it's NOT perfect, but if gives you an idea of how this works

We are doing a 100' dive:

total ascent time (with stops) is 6 mins (x2 divers) = 12 minutes of gas - SAC x average ATAs = 2, 12 minutes x 2 cu'/min = 24cu of air - and you can take it from there converting the cu to psi depending on yoru tank size. (it comes out to about 1000psi for an al 80)

HAPPY NOW, I'm giving away secret! No cool-aid for me ever again!

If you want more info or more units - take the class

OMG, 1000 psi for an al 80. what the hell do you think 1/3rds is? this is beyond the pale that you did all the math and come out with the same answer as I can in 1/100 of a second. and you want others to join? again OMG

Personally, I'd keep less than 1000 psi in reserve in an Al 80 for a 60 foot dive, and more than 1000 psi for a 100 foot dive.

Doesn't seem to do anyone any good to just say "OK, I'll just take a third of my total gas and keep it as a safety!" Pretty random and worthless, actually.

Its not 1/3...its rock bottom (in this case it happens to have the same value...your third to GUE's rock bottom)

If you were using a AL 80 with rules of thirds with the GUE system (and in this case a 100 ft dive)

The thirds would be 666 psi....go figure...another lucky number

Are you serious????? It's just luck that it came close to 1/3 on this example - (al80s get filled to 320psi by the way) if you want to do 3000psi the numbers will be different.

You really can't see how this totally different that thirds?

Yea...but I bet your not diving thirds on that AL80

you are so wrong. I didn't make this sh@t up, it comes from the wkpp as standards for overhead diving by the NSS-CDS. and those are the exact reasons that the long hose is the primary and the back up is for the donating diver because if it doesn't work only the donating diver will know and be able to fix it.


This is the perfect example of not knowing history and blindly following a cult that jacked everything from the NSS-CDS

Actually I'm from the agency that your agency branched off from according to the history I was taught by agency. I think you have your long hosed routed wrong and it must be cutting off the oxygen supply to your brain. The long hose is connected to the right post for the reason you mentioned. Again, I give you that. Again, this thread is about a rec rig...NO DOUBLES. Can you read...I'm starting to think not because if you could you would know that the agency that you so proudly claim to follow, doesn't advocate solo diving.
Good luck on that next 27 years.
